Default 1997 Mustang GT-Check Engine Error Code P1443

I recently had this error code come up, and I took the car to AutoZone and they did a check on the error code but were not able to to find what the error code was so I then googled it and found that the error code stands for Idle Air Control Valve (IAC), so then I purchased a new IAC and installed it and that fixed the problem, so if any one that has an error code P1443 then it's the IAC valve.

I hope this helps you.

Was your car idling poorly when you got the code?

Yes, and when switching gears from 1 to 2 the car felt like it was choking. Man I tell you what I am glad I replaced IAC valve now my car shifts good and drives smooth.

Very good. Finally someone that actually believes an error code and doesn't think it's some other wacked out cause.

Default Okay so...

I don't have a Mustang. I have a 97 Cougar with a 3.8.
I started getting this code after I ran out of gas the first time after changing my fuel pump. The light only comes on when the fuel is low. And then I reset it when I add gas. But it has to be reset or it just stays on.
So what I am wondering is what would trigger the code P1443 only when there is low fuel and how should I go about fixing it.
Thanks,
Connie
P.S.
I would appreciate anyone's help. You can email me at conniejackie@hotmail.com

well I hate to bust-your-bubble but a P1443 is an EVAP code NOT and IAC code....
glad to hear it's running well but, I doubt you've fixxed the problem, as that code, 443 on a 1996 to 1998 Mustang is a sign of a bad Cainster Purge Solenoid (E6ZZ-9C915-A) and a bad Thermistor/Flow Sensor (F57Z-14A606-BA).....

codes start wth either a PO or P1, depending on model and year... now IAC trouble codes are #'s 505, 506 & 507, so if it were an IAC issues the codes would have read P1505, P1506 OR P1507....

Question I have a 96 mustang with code P1443

I just got a 1996 mustang and drove it down the e-way at 70miles an hour and the check engine light popped on and wont go out. So i took it to autozone and they gave me the code P1443. Then the guy said it could be anything to do with emissions and that it must not be bad enough yet cuz the car runs fine. Now...it may run good and all but that light being on all the time is driving me nuts..lol Then i started searching on the net and found this site. Now...I see a couple threads on here that saids different things about code P1443..lol Such as...."
Cainster Purge Solenoid (E6ZZ-9C915-A) and a bad Thermistor/Flow Sensor (F57Z-14A606-BA)"...and "
Idle Air Control Valve (IAC)"
My question is...does anyone know what the real answer is to this P1443??? Please get back to me A.s.a.p. thanks!! James

I've never heard of 1443 being anything except evap. I have the code right now and just installed a new purge flow sensor, since that is what I've read is the most likely culprit. If that fails to fix it, I'll replace the solenoid.

I had the same code on my 97 GT. Changed the purge flow sensor and solenoid. Problem solved.

p1443 means that pcm noticed that the gas tank did not drop pressure nor reach vacuum.p means powertrain,1 means manufacturer specific,4 means emissions,the next four means canister or tank purge related,and 3 is that it didnt reach vacuum.

I am getting a P1443 but I also have P0172 System Too Rich Bank 1 and P0175 System Too Rich Bank 2. I have quite a few new parts on this car, all stock replacement. No Hi Pro yet. Just tryin to get it runnin right before I go adding too it. I have put the Freeze Frame info from a OBDII Reader on here also if this helps. Freeze Frame Information Parameter Description Value DTC for which Freeze Frame was Stored P0175 Fuel System 1 Status Closed Loop Fuel System 2 Status Not Supported Calculated LOAD Value 58.43 % Engine Coolant Temp 181.40 F Short Term Fuel Trim - Bank 1 4.69 % Long Term Fuel Trim - Bank 1 -25.00 % Short Term Fuel Trim - Bank 2 5.47 % Long Term Fuel Trim - Bank 2 -25.00 % Engine RPM 1,674.00 rpm Vehicle Speed Sensor 24.85 mph Any ideas I have read and see that it is most likey a solenoid stuck. Just would like some input before I tear into it. Thanks

Default ### SOLVED ### kinda

I fixed the P1443 code by going to the junk yard and getting a evaporator emission control solenoid off a 94 V-6 and that code is history. The solenoid is suppose to let the charcoal canister empty the fumes into the intake to be used. So the inline sensor was showing low/no flow so changed the solenoid and it's fixed. BUTTTTTT now I'm still getting a P0172, P0175 System Fuel Rich Bank 1 and 2. Any ideas??

I fixed it for $30 at a junk yard it was just annoying to see the check engine light on, long as thats the only code ya have then it's up to you. I did get a whopping 2mpg per tank of gas after changing it LOL
