I own a 2005 Mustang GT, I have several Modifications to the engine mostly cosmetic, Steel Braided hose, Plenum cover Ect. The three major engine mods I have is a K&N Cold Air Intake, Granatelli Motor Sports 62 mm Billet Throttle Body and Steeda Underdrive Pulleys.
The Problem Started last week when I hit a large puddle in a rain storm and the engine got real wet, a few hours later I got a Check Engine Light, I used my SCT II to view the DTC Code. It Showed a DTC P0340 Camshaft Position Sensor "A" Circuit" I reset the codes and the CEL came back the next day. So I dropped my car off at a Ford Dealer. They called me later and said that the problem is the generator, but they could not replace it under warranty because of the aftermarket underdrive pulleys, and he said that they may have damaged the generator.
I found a TSB in a Mustang forum - TSB 06-02-09 DTC P0340/P0344/P0345/P0349 - 4.6L 3V AND 5.4L 3V
Some 2005-2006 Mustang GT vehicles, equipped with 4.6L 3V engine, may exhibit a diagnostic trouble code (DTC) P0340 and/or P0344. This may be due to a malfunctioning diode or open phase connection in the generator.
I also Contacted Steeda Performance Parts in Pompano Beach, FL they stated that the underdrive pulleys only replace the Harmonic Balancer and Water pump pulleys, they do not touch the generator. They also stated to me that these pulleys were designed by ford engineers and are installed on some performance mustangs sold on some ford dealer’s lots including Saleen, SVT and Roush mustangs. So Ford can not deny warranty coverage of the alternator because of the Steeda pulleys.
They told me to go to SEMA.ORG website and Read the Magnuson-Moss Warranty Act, and that the dealer must prove that the aftermarket parts caused or contributed to the failure. I pointed this out to the dealer and they got very defensive and told me to take the car to my mechanic, put the stock pulleys on then if the car gets a code, they will fix it under warranty. Well this was going to cost me more time from work and cost to have the pulleys swapped out twice. I did not see anywhere in the law where the Burdon of proof falls on my shoulders to help him prove his case. He now is saying that Ford Corporate denied warranty on the generator and he will not replace it. I again pointed out that there are cars in his lot that have the same aftermarket products installed and they warranty them, his comment, theirs were installed by a certified Ford mechanics. (his comment here makes no sense). And How about the “Pattern of failure” the TSB, it does not say “if you have aftermarket parts installed you get this error”.
Even If I reinstall the stock Pulleys I am tagged in their computer as a problem, no ford dealer will help me, I asked Several in the area and they all say the same thing, WARRANTY VOID PERIOD. "we do not fix modded cars"
It's almost like the dealers want a peice of the aftermarket pie, I mean look at my Ford dealers lot, there are 06 mustangs with shaker hood scoops, the service adv. told me that the UDP cause the alternator to run outside it's designed specs. did I here the him right, does'nt modifying the stock intake filter box with a Ramair scoop cause it to run outside it's intended specs ???
These guys are trying to corner the market by bashing the competition and scaring the consumer.
I call BS on this crap. Kenne Bell says that Dealerships can't deny your warrenty with one of their systems installed....... If you can get away with the blower, underdrives shouldn't be a problem, espeically on a par that they don't even affect.
Take it to some higher ups, call the right people and get a lawsuit on them!
Does the supercharger void my new vehicle warranty?
No. It is against Federal Law for a Dealer to refuse a warranty claim because an aftermarket product has been installed on your vehicle. If a warranty is denied, contact the Environmental Protection Agency (EPA) at (202) 260-2080 or www.epa.gov or the Federal Trade Commission (FTC) at (202) 326-3128 or www.ftc.gov. Additional information is available at the SEMA (Specialty Equipment Manufacturers Association) website www.sema.org. Kenne Bell is a member of SEMA.
I agree, This is BS, the dealer you brought it to and had you car flagged is an outright A$$hole, He did this on purpose for 1 of 2 reasons, eather he's too stupid to understand how underdrive pulleys work (less wear and tear) or he's jealous of you car because he doesn't have one or he doesn't like you because you do. No way do I see the relation between you UDP's and the alt failure. Like jcovercash said take this higher up, they need to explain how the UDP"s caused the failure, Id like to here it.

Yea and if THEY THEMSELVES can't prove that it caused the failure they are obligated to fix it. You should not have to take it somewhere else and pay to have it diagnosed, etc... They have to tkae time to do it, and if they can't prove 100% that it caused it then they are obligated to fix and as covered by your warranty.
Mayby call the BBB, they might be able to give you the phone number of who to contact at Ford

SOME 2005-2006 F-SUPER DUTY AND EXPEDITION/ NAVIGATOR AND 2004-2005 F-150, EQUIPPED WITH 5.4L 3V ENGINE, AND 2005-2006 MUSTANG GT VEHICLES, EQUIPPED WITH 4.6L 3V ENGINE, MAY EXHIBIT A DIAGNOSTIC TROUBLE CODE (DTC) P0340 AND/ OR P0344; OR 2006 EXPLORER 4DR/ MOUNTAINEER EQUIPPED WITH A 4.6L 3V ENGINE MAY EXHIBIT A DTC P0345 AND/ OR P0349. THIS MAY BE DUE TO A MALFUNCTIONING DIODE OR OPEN PHASE CONNECTION IN THE GENERATOR. PERFORM A GENERATOR FREQUENCY TEST TO DIAGNOSE CAUSE OF CONCERN. DO NOT REPLACE THE GENERATOR UNLESS A FREQUENCY TEST INDICATES A FAULT. THIS TSB PROVIDES STEP-BY-STEP DIRECTION FOR PERFORMING A GENERATOR FREQUENCY TEST USING THE WDS OSCILLOSCOPE FUNCTION. See TSB for complete details EFFECTIVE DATE: 01/20/2006
This article supersedes TSB 05-23-17 to update the vehicle line coverage. ISSUE:
Some 2005-2006 F-Super Duty and Expedition/Navigator and 2004-2005 F-150 vehicles, equipped with 5.4L 3V engine, and 2005-2006 Mustang GT vehicles, equipped with 4.6L 3V engine, may exhibit a diagnostic trouble code (DTC) P0340 and/or P0344; or 2006 Explorer 4dr/Mountaineer equipped with a 4.6L 3V engine may exhibit a (DTC) P0345 and/or P0349. This may be due to a malfunctioning diode or open phase connection in the generator. ACTION:
Perform a generator frequency test to diagnose cause of concern. Do not replace the generator unless a frequency test indicates a fault. This TSB provides step-by-step directions for performing a generator frequency test using the WDS oscilloscope function. SERVICE PROCEDURE
NOTE:USING THE OSCILLOSCOPE TO MEASURE PEAK-TO-PEAK VOLTAGE IS NOT A GOOD INDICATOR OF A FAULTY GENERATOR.
NOTE:ENSURE THERE IS NO BATTERY CHARGER CONNECTED TO THE VEHICLE.
Ensure the connections to the battery terminals, engine grounds, and generator B+ are clean and secure.
Attach WDS battery cable clamps to battery/battery cables.
Turn on WDS.
Select the Toolbox Icon, (upper left of WDS screen).
Select Oscilloscope and then click OK.
Select Channel 1, Auto, Generator Ripple.
Select Calculations, Channel 1, Frequency.
Select Calculations again.
Push the RUN/STOP button. A waveform should display on the screen.
Start the vehicle and leave at idle (engine speed less than 800 RPM).
Turn on vehicle loads (high beams, blower set on high, heated seats, defroster, etc).
Examine the frequency reading on WDS. NOTE:WDS CAN CALCULATE THE FREQUENCY AUTOMATICALLY. THE CALCULATED FREQUENCY IS LOCATED ON THE LOWER LEFT AREA OF THE OSCILLOSCOPE SCREEN. SOMETIMES THE FREQUENCY CANNOT BE CALCULATED BECAUSE THE WDS CANNOT RECOGNIZE AND MEASURE PEAK VALUES. IF THE WDS CANNOT CALCULATE THE FREQUENCY, IT WILL DISPLAY "INVALID" WHERE THE FREQUENCY READING SHOULD BE. THIS IS NORMAL IF THE RIPPLE VOLTAGE IS TOO LOW.
For a proper visible wave pattern, adjust the voltage scale and time scale until a good wave pattern is visible. Typically, a setting of 1mS/div and 100mV/div is a good starting point and can be adjusted as necessary.
Run vehicle until signal is steady. Then select the "RUN/STOP" button to freeze the waveform.
Determine if the generator is faulty based on frequency measurement: NOTE:FREQUENCY IS DEPENDENT ON ENGINE RPM. PERFORM ALL TESTS AT IDLE OR FREQUENCY READINGS WILL BE INACCURATE.
Compare the WDS saved waveform to the sample waveforms in Figure 1. If measured ripple frequency is lower than 500 Hz, then generator is faulty and should be replaced. If generator is not faulty proceed to Step 16.
If frequency calculation cannot be made by WDS, it can be calculated manually. See MANUALLY CALCULATE FREQUENCY. If calculated ripple frequency is lower than 500 Hz, then generator is faulty and should be replaced. If generator is not faulty proceed to Step 16. MANUALLY CALCULATE FREQUENCY
Count the number of complete voltage dips over a given range of divisions on the scope trace
Divide the number of voltage dips by the number of divisions to get the average voltage dips/division
Divide the value in Step 2 by the time scale (e.g. 1mS/div = .001 sec/division) to get frequency
NOTE:THIS METHOD OF CALCULATING FREQUENCY IS SLIGHTLY DIFFERENT THAN THE METHOD USED BY WDS, SO THE FREQUENCY MEASUREMENT VS. CALCULATED MAY BE SLIGHTLY DIFFERENT.
If the frequency test does not indicate a fault with the generator, proceed with normal Powertrain Controls/Emissions Diagnosis (PC/ED) diagnostics for the DTC. For F-Super Duty vehicles only, if the DTCs are still present after diagnostics, reprogram the powertrain control module (PCM) to the latest calibration using WDS release B38.11 and higher or B39.2 and higher. Calibration files may also be obtained at www.motorcraft.com. This new calibration is not included in the B39 CD. (DO NOT REPROGRAM EXPEDITION/NAVIGATOR, F-150, MUSTANG, OR EXPLORER/MOUNTAINEER).

Sorry to hear about your dilemma. Did you realize that the pulleys would reduce the alternator speed? Putting the original pulley set back isn't that big of a job. You should be able to do it even quicker this time. Then the dealer should replace the alternator. Hopefully you haven't damaged your relationship with the service manager. You need to calm down, buy two- dozen Krispy-Kremes on the way back to the dealer, give them the donuts and ask them to look at your problem again. I'm sure you'll get 24-posts on this board that know all the policies and laws, and that all car dealers employ only morons. Especially salesmen. Unfortunately that doesn't help your situation. Escalating a shouting match with the service writer will only get you banned from their service department. I see it often. You changing the pulley makes you partly to blame, and a service writer that may have been having a bad day was also to blame. Try to repair this. Life is too short to stress over a failed part.

"boss377" is correct - cooler heads will prevail. If it is such a disagreement between the aftermarket company and Ford - suggest to the aftermarket company that they pay for the repairs. That will not happen either.
Yes, Ford wants the aftermarket business too and if they install or have installed an aftermarket part, I would imagine there is sort of an agreement between Ford and the aftermarket company.
I agree with the cooler head approach but I am have a firm belief that most businesses will try to screw the customer because of the "ALL MIGHTY DOLLAR".
I had a Lexus 400 and the moon roof failed to close. I was told by the dealer, after he had walked me from the customer lounge, that it was not covered under warranty and the cost to fix would be $1200.00. I told him to forget it, put it in the closed position,and I would wrtie a complaint to Lexus. Minutes later he came back to the lounge and told me it was my lucky day since he discovered there was a TSB on the problem and it would be fixed free of charge. So they tried to screw me from the start and why is that? "THE ALMIGHTY DOLLAR!!!!!"
That sucks -- I had a Benz and the dealer tried telling me that I would need $1,500 worth of repairs on my car ( power steering pump) etc... I advised him that this car had been in the shop a month earlier and needed to have the hoses tightend or something accroding to a TSB, and after advising me I could drive the car there - even with it making a loud a$$ noise. Now the power steering pump leading directly from the hoses mysteriously dies? The TSB stated to change the hoses and they only tightened them. Finally after arguing and telling them that I was trading my car in for something else other than a Benz in the next month ... then magincally they said they would replace free of cost. OF COURSE I had to argue a bit and state that since a part failed on their design that then caused to depandant part to also fail - they MUST be responsible then to fix what they caused!
Goood Luck with it all.... Sometimes they are just too corporate to give a damn!

I Know I Sound Like A Wus, But This Is Why I Never Mod Engine Until Warranty Is Up. I Fought With Dodge Once Because My Cat Rotted Out And They Didn't Want To Cover It Because I Put Cat Back Duals On. Dealers Can Be Tough, Especially If You Try To Take It To A Dealer You Didn't Buy It From.

Don't even mess with the service guys, they're only the middle man. May have given the regional person his/her own two cents.
The guys at my dealership really went to bat for me on my Focus (bought it used from ANOTHER dealership!!) and it had a bottom sucking CAI I didn't know about -sucked in water and blew the engine.
Ford replaced it under warranty, even though they didn't need to -but, then again, I'm a lifelong customer . . .

True....true, try the cool headed approach first, second & if you're really good try it a 3rd time.
My story involves a computer.....but can be applied in many situations. I was sold a #$%@*! up computer and had issues with customer service at an unnamed store (Best Buy). After 2 or 3 rounds I went balistic (not like police needed balistic) but, to make long story short, I started getting loud around many potential customers about how they don't back their products, etc, etc, etc.
Amazing, within minutes a GM appeared and offered me a new computer with a memory upgrade for free!!
