What does the code p2127 on a check engine light mean?
The P2127 code means that the throttle or pedal position sensor switch E has a low input. The pedal position sensor is a sensor found on the gas pedal. The sensor tells the ECU when the gas pedal is depressed and how far it is depressed. When the ECU detects a low input from the pedal, it will trigger the Check Engine Light and the code P2127.
Why is my oil pressure sensor not working?
You could have the wrong oil in the vehicle, or you could not have enough oil in the vehicle. If you have a leak, this is a possibility. When caught soon, it is possible to repair. Waiting too long could lead to your engine seizing up and that would necessitate more repairs or possibly the replacement of the engine.
What does the p0523 code on the oil pressure sensor mean?
What the P0523 code means. This code means that the Powertrain Control Module, or PCM, finds that the engine oil pressure sender/sensor is too high. The cause could be mechanical or electrical.
What is the p2138 code on GM vehicles?
GM has issued a technical service bulletin # 07-06-04-019D to address a P2138 Reduced Power issue. 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:
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.
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.
How much does it cost to repair a p2138 Chevy?

What is the p2138 code on a throttle body?
Photo of a throttle body, throttle body position (TPS) sensor is the black part to the lower right: The computer monitors the correlation of both voltages. When both voltages agree, the system is functioning properly. When they deviate for two seconds, the code P2138 is set indicating a malfunction somewhere in the system.
What is the p2138 code on a Pontiac Grand Prix?
Hi all, I have a 2007 Pontiac Grand Prix with sunroof which is throwing code P2138. This has been going on for nearly a year now. When driving in rain or very wet road conditions the Reduced Engine Power message will come on along with the check engine.

What does p2122 mean on the throttle position sensor?
A P2122 code means that the the car’s computer has detected that the TPS (throttle position sensor) is reporting too low a voltage.
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 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.
