I had posted several months back about RPMs fluctuating about 200 rpm then back down when running steady speed. P2138 Meaning The Accelerator Pedal Position (APP) sensor is an input to the Powertrain Control Module and used to determine the amount of torque requested by the operator. Now that we are already aware of how a throttle position sensor facilitates the engine to adjust the correct amount of fuel in the vehicle so that it feeds the right data to the computer time and again, a slight malfunctioning in the sensor creates a host of problems. The throttle position should be 9-12% at idle - if the number is off then at least you’ll know the sensor / ecu aren’t doing the right thing. Our GM parts and accessories are expedited directly from authorized GM dealers strategically located all across the U. The TPS is a sensor within the electronic throttle body that measures the position of the throttle.

Thanks for using 2carPros. cari alat ganti kereta. To ensure reliability, purchase GM part # 15833646 Pedal Asm,Accelerator (W/ Position Sensor). I have a 06' duramax 6. If you do not have an account but would like to check CHEVROLET > 2006 > EQUINOX > 3. The APS is basically a throttle position sensor (TPS) with a pedal attached. 8L L4 > Interior > Accelerator Pedal Position Sensor. Measure the amperage from the 5-volt reference circuit of APP sensor 1 to the low reference circuit of APP sensor 1, with a DMM. When the accelerator pedal is moved from the idle position to the fully opened position, the resistance between the accelerator pedal position sensor (main) output terminal and ground terminal will increase according to the depression. 2 Volts [1] Typically, accelerator pedal travel only yields 4. However I can't seem to track down a wiring diagram for the pins at the pedal sensor.
