The throttle position sensor is located on the side of the throttle body attached to the throttle shaft and held in place with two small screws, if it is bad you just replace it there is no adjustment. To reset the check engine lamp you need a OBDII scan tool which plugs into the diagnostic connector under dash on drivers side.

Resetting it will not help, as the ECM (Electronic control module will readjust thus same issue. If the engine is running sluggish at a very low idle, but fine when the RMP is increased, it is probally the pcv valve, actually the hose part that goes into the back of your Carb., check this by spraying starting fluid, ether, towards the back of fuel intake while running at idle, if it revs, Bingo! Be very carefull not to start a fire, and keep an extinguisher handy!!!

Gm code p2120


Code p2120 is accelerator pedal position sensor APP sensor 1 circuit apparently this is known as the reduced engine power syndrome and is quite common on the avalanche. There is no mechanical linkage from gas pedal to throttle body and it is quite common for the throttle position sensor located on throttle body to mess up and throw this code and also for one of the wires to the throttle position sensor to get hot become brittle and sometimes break. I would start there

Trac off light comes on & then car shifts hard. When we shut it off & then re-start it, it works fine. Any ideas?


Youll need to scan for transmission codes. the trac off light is a default of the trans going into a default safety mode. Bad speed sensors and simple little bolt on items like that can cause this problem.-------- But as you mentioned in your question that " When we shut it off & then re-start it, it works fine." this indicates that computer gets reset when you turn car on off. so there is error code stored, but its getting reset.Get the car scanned at autozone service center or at local car garage and retrieve the error codes, that will point towards the cause of the problem.------- Mostly its ABS wheel sensors causing the problem.----------- Also other possibility for this trac light coming on and car hard shifting is problem with iat sensor or problem with tps sensor.------- The Intake Air Temperature (IAT) sensor determines the air temperature inside the intake manifold. Resistance changes in response to the ambient air temperature. The sensor has a negative temperature coefficient. As the temperature of the sensor rises the resistance across the sensor decreases. This provides a signal to the PCM indicating the temperature of the incoming air charge. This sensor helps the PCM to determine spark timing and air/fuel ratio. Information from this sensor is added to the pressure sensor information to calculate the air mass being sent to the cylinders. The IAT is a two wire sensor, a 5-volt reference signal is sent to the sensor and the signal return is based upon the change in the measured resistance due to temperature.The IAT sensor is located in the air cleaner outlet tube.--------- The throttle position sensor, also called the TP sensor, helps to regulate the throttle position on a car's engine. A faulty TP sensor can cause an illuminated check engine light in your Cavalier, as well as cause the engine to run inefficiently. Replacing the TP sensor is simple, quick and inexpensive.
Locate the throttle position sensor. The sensor is attached to the rear of the throttle body. Disconnect the electrical connection from the sensor.
Pull the throttle position sensor off; you may have to wiggle it back and forth to remove it.-------
---------------------- So first get car scanned at car diagnosis center, and get error code.The error code will exactly point, which part is causing the problem.But if in case no error code is retrieved, then this possible parts mentioned needs to be tested and faulty one will have to be replaced.----------- This will help, thanks.Helpmech.

My 2003 chevy truck goes into limp mode and pulls code PO220.Where is the tps sensor located?


Symptoms - Engine Light ON (or Service Engine Soon Warning Light)
- No throttle response Possible Causes - Harness or connector (The TP sensor circuit is open or shorted.)
- Electric Throttle Control Actuator (or Throttle Body Motor)
- Accelerator Pedal Position Sensor (APP) P0220 Description Electric Throttle Control Actuator consists of throttle control motor, throttle position (TP)sensor, etc. The throttle position sensor responds to the throttle valve movement.
The throttle position sensor has the two sensors. These sensors are a kind of potentiometers which transform the throttle valve position into output voltage, and emit the voltage signal to the ECM. In addition, these sensors detect the opening and closing speed of the throttle valve and feed the voltage signals to the ECM. The ECM judges the current opening angle of the throttle valve from these signals and the ECM controls the throttle control motor to make the throttle valve opening angle properly in response to driving condition.
When is the code detected? An unexpected voltage from the TP sensor is sent to ECM.

Check engine light came on diagnostic said it was throttle position sensor i need to find out where it is located so i can replace it


The throttle position sensor is located between the air filter box and the intake manifold. If you aren't familiar with engines, the air filter box is usually located behind the driver's side headlight. There is a rubber tunnel that runs from the air box to the intake manifold. Between the rubber tunnel and the intake manifold you will find the throttle bolted to the intake manifold. The sensor is located on the throttle.

2005 - engine sputters when engine speed decreas


you can try reseting the cpu first by disconnecting both positive and ground wire from battery for about a hour or so and if that does not work. I could be the throttle position which is located on lower right side of throttle body on top of engine removes with 2 screws and one wire harness very easy to replace.And if it is the sensor then u will have to disconnect battery in order to reset the sensor with the computer.

Code p0121 TPS


THERE IS A TP SENSOR BUILT INTO THE THROTTLE ACTUATOR. THESE TRUCKS HAVE BEEN KNOWN FOR A FEW PROBLEMS IN THIS AREA. THROTTLE ACTUATOR IS NOT SERVICEABLE. THE THROTTLE BODY WILL NEED TO BE REPLACED IF IT IS PROVEN FAULTY. THE APP SENSORS ARE LOCATED IN THE GAS PEDAL MODULE. THESE SEND SIGNAL TO COMPUTER TO TELL IT WHERE YOUR FOOT IS, THEN COMPUTER SENDS COMMAND TO THROTTLE ACTUATOR TO OPEN OR CLOSE THROTTLE BASED ON THIS INPUT. THE SENSOR IN THE THROTTLE ACTUATOR DELIVERS A MESSAGE BACK TO THE COMPUTER TO TELL IT WHAT THE ACTUAL THROTTLE POSITION IS. IF THESE SIGNALS DONT MATCH(WHERE THROTTLE IS COMMANDED AND WHERE IT ACTUALLY IS)THE CHECK ENGINE LIGHT WILL ILLUMINATE AND THE VEHICLE COULD GO INTO A REDUCED POWER MODE. HOPE THIS HELPS YOU!
