Stalls intermittently, wrench icon lights up under tach.


Problem with the electronic throttle control .
It should be noted that the ETC system includes a wrench light on the instrument cluster that illuminates when a fault is detected. Faults are also accompanied by DTCS and the "Check Engine Soon" light. Your best bet is to take your vehicle to a reputable ASE certified repair shop .
Overview The Generation II (Gen II) Torque Based Electronic Throttle Control (ETC) is a hardware and software strategy that delivers a transmission output shaft torque (via throttle angle) based on driver demand (pedal position). It utilizes an electronic throttle body, the PCM and a accelerator pedal assembly to control throttle opening and engine torque. The ETC system basically replaces the standard cable operated accelerator pedal, idle air control (IAC) motor, 3-wire throttle position sensor (TPS) and mechanical throttle body .

2007 ford expedition wont rev past 2500 rpms in park or goin down the road


Start by checking your TPS switch (throttle position sensor) located on the throttle body . They turn while your foot pushes the accelerator pedal . TPS voltage goes from 0 to 5 volts and is easily checked with a volt meter .

Where is the tps located?


TPS means Throttle Plate Position sensor. It is installed on electronic fuel injection engines produced after 1996. TPS is attached to the side of the throttle body which converts the mechanical movement of the accelerator pedal to electronic signals. After receiving the signals from TPS. the Electronic Control Module (ECM) assumes, how much accelerator pedal is depressed by the driver and so it adjust the on time of the fuel injectors to deliver the metered quantity of the fuel to each cylinder and to adjust the ignition timing as well.

Can you adjust the TPS on a 2001 Corolla? If yes how do you adjust it?


The best way to adjust the TP position sensor is by a scan tool. With the accelerator pedal fully released the value should be between 9.8% - 18%.

I have a problem with my toyota corolla ae110. when i step on the accelerator it delays to pickup the speed.its is an auomatic transmission


Hi.

If the problem is transmission because the gears do not engage at the right time, then check the TPS. The TPS is the throttle position sensor. TPS is located on the throttle body, and detects the way you push the accelerator pedal. Along with speed sensor, the signal from TPS is used by the TCM (transmission control module) to decide when to shift gears. If the TPS is defective, the transmission will shift at the wrong time.
The TPS can be tested reading Volts (or Ohms) at TPS contacts while someone else is slowly pressing the pedal. If there gaps or irregularities in the reading, then the TPS is faulty.

If transmission is OK ensure that the problem is not the engine. An incorrect mixture or injection problems may result in slower performance.

Regards.

I have a Jetta TDI 1993 Model and I have a problem, while driving the I get no response from the accelerator pedal, the car seems to idle but there is no accelerating power. If turn the engine off and on...


Go back to that VW dealer and complain. I'm sure you payed plenty, and I know in my shop, if a customer's car is not repaired to their satisfaction, I want to know, and make it right. Sometimes parts can be bad right out of the box, and sometimes problems are misdiagnosed. Go back, but don't agree to pay for anything untill you get a satisfactory explanation. Good luck.

On a 04 camry with 2.4 ltr engine, can I replace just the throttle position sensor or do i have to replace the entire throttle body? The engine code said faulty throttle body.


I think the terms "Throttle Positon Sensor", TPS and "Throttle Body" can be misleading at least in regards to the 04 Camry.

My 04 Camry gave a diagnostic reading of P2121 for my problem "Throttle PEDAL position switch D circuit". However, we changed out the complete Throttle Body/TPS (Toyota Part #22030-0H020) that did NOT fix problem.

The 04 Camry TPS Electronic Module "Throttle Positon Sensor" is factory assembled and riveted to the side of the throttle body. The only way to service/inspect it would be to cut off or drill out the rivets. Not sure you could open the darn thing if you got it off, but that seems to be the only way Toyota sells them!!

Hopefully a new Throttle PEDAL Position Sensor (Toyota Part # 78010-33010 PEDAL ASSY, ACC)
will fix it. This is located under the dash near the accelerator pedal.

So, now I would recommend FIRST to replace the "Throttle PEDAL Positon Sensor" (it is much, much cheaper) and then the Throttle Body/TPS assembly!! Unless of course, you get a diagnostic code as you did for "faulty throttle body!!
