What causes the p2122 fault code to register?
While there are multiple potential causes for the P2122 fault code registering, one of four components is likely defective – the throttle position sensor, the throttle actuator control motor, the throttle position actuator, or the pedal position sensor.
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.
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 is the p2138 throttle position sensor and switch?
P2138 Throttle/Pedal Pos Sensor/Switch D/E Voltage Correlation Trouble Code Fault Location Probable Cause P2138 Throttle position (TP) sensor/switch D/E Wiring, TP sensor/switch
When do I get a p2138 problem code?
The P2138 trouble code is triggered when there are problems with the throttle/pedal position sensor/switch. However, it’s not the only code related to the throttle body and its circuitry. The P2135, P2136, P2137, P2139, and P2140 DTCs also indicate issues in the same areas.
What does the p2122 OBD-II trouble code mean?
The P2122 OBD-II trouble, or fault, code means that the vehicle’s on-board computer has detected low voltage in the throttle position sensor (TPS), which is usually below 0.17 volts. What the P2122 code means The registration of the P2122 trouble code simply means that low voltage has been detected in the TPS.
Where is the p2138 reduced power Bulletin located?
The P2138 trouble code may be stored in the computer along with a check engine light. The P2138 Reduced Power bulletin applies to the following vehicles: 2005-2011 GM Passenger Cars and Light Duty Trucks (Including Saturn) The P2128 trouble code refers to Accelerator Pedal Position (APP) Sensor 1-2 Correlation.
What does trouble code p2128 mean on a GMC Sierra?
The P2128 trouble code refers to Accelerator Pedal Position (APP) Sensor 1-2 Correlation. Do NOT assume you have a bad accelerator pedal sensor. GM says the condition is caused by water leaking into the body harness connector that carries the APP signal to the PCM. The water changes the voltage readings from the APP.
