What are the possible causes of p2138 code?
P2138 Possible Causes 1 Accelerator Pedal Position Sensor harness is open or shorted 2 Accelerator Pedal Position Sensor circuit poor electrical connection 3 Faulty Accelerator Pedal Position Sensor 4 Faulty Electric Throttle Control Actuator
What does p2138 mean on a powertrain control module?
I have dealt with a stored code P2138 on many occasions and I have found that it means the powertrain control module (PCM) has detected a discrepancy in the voltage signal between a particular throttle position sensor (TPS) and a particular pedal position sensor (PPS). D/E refers to a particular circuit, sensor, or area of a particular circuit.
What is the p2138 code on a Honda Pilot?
2008 Honda Pilot Car had the P2138 code, took the sensor off the throttle body and cleaned it. Car worked ok for a couple months. Now threw the code again. Reading around it could also be the Accelerator position sensor?
What does the p2138 Chevy app sensor mean?
P2138 Chevrolet Meaning. The Accelerator Pedal Position (APP) sensor is made up of 2 sensors that are housed inside one assembly. The Engine Control Module (ECM) supplies a separate 5-volt reference circuit and a low reference circuit for each of the sensors.
What does the p2138 code in engine control mean?
What the P2138 code means The P2138 trouble code indicates that the Engine Control Module has detected a malfunction within the D and/or E circuits of the throttle position sensor. What are the causes of the P2138 code? A defective throttle body motor
What to do if your p2138 is not working?
Use the scanner to retrieve all stored trouble codes and write them down for future reference. You may also want to keep any related freeze frame data. Your notes may prove helpful if the P2138 is intermittent. Clear the codes and test drive the vehicle. If the code is reset, continue with the diagnosis.
