2004 chrysler sebring 3.0 stalls and will not idle. Engine lite came on and scanner said TPS low voltage on one side. I replaced TPS and it temporarily idled ok. Engine light is now off. Runs fine except...


This is where proper diagnosis comes in...as the TPS sensor voltage low because of a failed TPS sensor? Or was the TPS voltage low due to low battery voltage at the control module? Did you bother to check for the proper voltage at the TPS sensor connector before throwing parts at the problem? If the battery voltage goes low, it is NORMAL for the engine to not idle correctly. Low voltage at the control module can cause the computer to lose all of its "learned" data. It will have to "re-learn" how to idle the engine. This can sometimes take a few days. This is exactly WHY I keep telling people to not be disconnecting batteries in an attempt to "clear" computer fault codes.
If your battery has been going dead, you need to properly test and diagnose your battery and charging system. If this system is not working correctly, there is NO WAY your computer network can function correctly. - this MUST be diagnosed and repaired FIRST!

Hi.

From your description it looks like you have a defective TPS (The TPS is the position sensor on top of the throttle body that you are disconnecting).

Signal from the TPS is very important for different vehicle's functions. Among other thing the TPS output is used by the electronic ignition system to determine the fuel mixture being injected and by the automatic transmission to determine when to change gear. In your case the transmission was probably not shifting into higher gears, for that reason the engine was not revving above 2K rpm.

The TPS can be tested reading voltage at its terminals while someone operates the throttle pedal. Voltage must increase/decrease smoothly and stay in range, otherwise the TPS must be replaced.

As said at start your problem is likely a defective TPS. The fault is quite common and it is fixed replacing the TPS.

Regards.

TPS Sensors issues, are common on all vehicles.
Yes, you could misdiagnose anything, on todays high tech vehicles,if you don't know the components,how they work and how they function in a system. If the sensor wasn't tested at all,you need a new mechanic. Even the pros throw parts at it.
If the TPS needs replacing, you can do it yourself. Go to the auto parts store and buy it. Look it up on NAPA site or others. About $75.00. Too easy, to pay someone to do.
A scanner code doesn't mean replace something. That was were you were going with your question. Always test,then replace. Test,not scan
Do this. Go to a shop,stand next to your vehicle, and have somone test it in front of you,not scan the system,actually test the TPS. Back probe it and put a Meter or Oscilloscope on it.

I would change your throttle position sensor (TPS) or at least check all related wiring, fuses and relays concerning this device. It is located on the outside of the throttle body at the end of the throttle plate shaft. Its function is to send a an electrical signal to the ECU that correspnds to the position of the throttle plate. Your TPS is not sending a signal to the ECU so the ECU does not know to inject more fuel in response to the throttle being opened. The call for more fuel in the absence of immediate input from the TPS is being made to the ECU by the Manifold air pressure sensor but this can a take a second or two to respond to pressure changes, hence the hesitation in acceleration. One really quick way to check is to simply disconnect the TPS electrical connector. If it were running normally you will notice an immediate change in engine idle, as your is faulty you will notice no difference

I have a 2002 Ford Escape that starts ok, but when you attempt to give it gas, it bogs down and the engine cuts out. If you start it and do nothing, it will idle at a very very low RPM.

Engine surges not responsive to WOT


SOUNDS LIKE THE T.P.S. IS NOT FUNCTIONING. ALTHOUGH IT MAY TEST OK, IF IT IS NOT RESPONDING, THEN IT MUST BE REPLACED. UNLESS YOU HAVE A FUSE FOR THE TPS, THEN IT MUST BE THE ONLY REASON FOR NO THROTTLE RESPONSE. HOPE THIS HELPS. PLEASE KEEP ME POSTED. THANKS FOR USING FIX-YA. AND FOR AN HONEST RATING IN ADVANCE. GOOD LUCK.
