07 SATURN ION2.CODEACCELERATOR THROTTLE POSITION SENSOR.CAR HAS STRONG GAS SMELL.RUNs ROUGH & HARD TO START.BAD GAS MILEAGE.SAW GAS LEAK UNDER BACK OF CAR TODAY.CAN THIS DUE TO THE ACCELERATOR TPS?


No, these are separate problems, but both may affect mileage. You will have to find and repair the leak. For the code, we need the actual trouble code to help you. The accelerator pedal position sensor and tps are actually separate sensors, so your words confuse me. The pedal position sensor us on the pedal and is used to tell, the throttle controller how wide to open the throttle. When this sensor is not working, the car will usually not run, because the computer is afraid of overrevving the engine. The tps measures the actual throttle opening and is used by the pcm to adjust the fuel/air mixture to meet demands. When this sensor is not working, the engine will run but accelerate poorly or stall. In either case, do not assume the sensor is the cause of the trouble code. The issue could be a fuse, relay, or wiring as well. That is why we need the actual code to provide test procedures you can use to diagnose the actual failure mode and affect the appropriate repair.

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 .

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 .

I have a 1999 pontiac grand prix GTP. i changed the TPS but now my transmission is shifting late. im getting a code for the TPS but its new. someone told me that there might be a TPS by the gas pedal, but...


TPS by the gas pedal.. Your vehicle doesn't electronic throttle control ,an it's not a TPS at the gas pedal . IT's a APP - accelerator pedal position sensor. im thinking it might be the speed sensor???? A speed sensor is not going to set a TPS code , don't care if sensors is new , Electrical circuits involved , PCM - engine computer . If all you can do is guess your best bet , take it to a qualified repair shop.

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.

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.

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.
