Default does anyone know how to clean the throttle position sensor

i read somewhere on the forum that you can clean the tps sensor because it can become contaminated and cause false reading and my car has all the symptoms of the sensor being faulty. so i was wondering if i could clean it and then go on from there any tips are nice.

you did all that and it still didnt work? im going insane here the problem stopped for a year and now it came back. the only other thing i can think of is the tsb for the fuel pump sucking bubbles in but it doesnt make sense for crappy idle. did you clean the intake air temp sensor too.

Do you mean clean the throttle body? Buy some CRC throttlebody cleaner and this video shows you how to clean it.
Mustang Tech Information by Brenspeed
Its the first video.
You may also want to clean your MAF sensor with CRC Mass Air flow sensor. When you remove the MAF sensor do not touch anypart of it that was in the housing. Just spray on the cleaner and let it dry completly before reassambly.
You might want to check yor TPS voltage to make sure its within spec. 1.19-1.31
BBK Twin 62mm (2005+ GT) Mustang Throttle Body - Trouble Shooting Guide at AmericanMuscle.com
The first part is how to check the voltage.

The tps is a sealed sensor. It rotates with the throttle plate and sends voltage readings to the engine computer. There is no way to "clean" it. You can adjust the position at idle by reading the voltage with a meter.

You can clean the wires on the airflow sensor that is in the Mass Air. They can get contaminated with oil from aftermarket oiled filters. Be very gentle when you do this. I use a can of electric clean and spray them. It drys with no residue. The hot wire goes to 200 degress + ambient and the rate at which it cools determins how much airflow is entering the motor. GA

This is a myth. I have over 250K miles total on oiled filters on multiple vehicles with no MAF issues.

idle problems can be from a vacumm leak or dirty air flow sensor. As said before becareful cleaning it. also ford has a updated tps sensor which I replaced because my GT keep going into limp mode,bad corralation between sensor a&b (throttle circut) hope this helps. I have the sct tuner which sometimes the idle changes so reload the tune again and raise ilde speed

Just because YOU have never had a problem does not mean it is a myth. What about those people who cleaned their oiled filter and put way too much oil on the cloth. I have seen this a number of times. The hot wire usually will self clean due to the heat, but the ambient wire gets pretty gunked up. A simple blast of cleaner takes care of it.

i think i figured out the problem and its not sensor. i said forget it and took it to ford cause i have an extended warranty so what the hell. they said the alternator, alternator harness and battery were shot. they also said that my hids put strain on the charging system but they still warrantied it however the second i left the dealership the car still stalled when i got on it. the idle was fine as long as i kept the lights off. so i took the hids out and put the stock bulbs in. it made no difference whenever i turn the lights on the car is all messed up. but then it started doing it all the time again. i think theres a short somewhere thats drawing on the whole system and car isnt getting enough juice when i get on it. i took it back to ford last night and told them what i thought well see what happens.

Hey anybody, I am throwing the P2104 & P2111 code with my Ford GT500 t/b. Before I trying taking it apart, I had a stupid question. When I maually open the throttle body, should it stay open of close on it's own? I always thought it should kind of snap shut when you let go but i have to manually close mine.

Yes it should close on it's own.

Really? If I reach through the front and push it open and then push it closed, you can feel the gears turning but if I stop it stays in the position I last put it in. Do you or anybody have any idea what to do. Like mentioned, it is the actual Ford GT/500 t/b and I only have like 3000 miles in it. Thanks again.
