What causes code P2138?

Diagnostic trouble code (DTC) P2138 stands for “Throttle/Pedal Position Sensor/Switch D/E Voltage Correlation.” It is triggered when the vehicle’s engine control module (ECM) or powertrain control module (PCM) detects that the signals from the two throttle position sensors (or two accelerator pedal position sensors) do …

What is Engine code p1125?

Zitat von Youtube: P1125 is a diagnostic trouble code for throttle position sensor intermittent. Under this circumstance stop driving and repair your vehicle immediately.

What causes a P2122 code?

Meaning. The P2122 trouble code log means that a low voltage is detected at the TPS and is set when the Powertrain Control Module (PCM) detects an abnormally low input voltage from the sensor or circuit in the throttle control system that is marked as “D”.

Can I drive with code P2122?

If the cause is a faulty accelerator pedal position sensor, then it is most likely open, shorted, or has a poor electrical circuit connection. The accelerator pedal sensor transmits the position of the accelerator pedal to the engine control unit, so you can drive immediately.

How do I fix code P2138?

What repairs can fix the P2138 code?

  2. Repairing or replacing wiring that is associated with the throttle body motor.
  3. Replacing the throttle position sensor.
  4. Repairing or replacing wiring that is associated with the throttle position sensor.

Can I drive my car with a P2138 code?

If your car displays the engine code P2138, then your car’s computer is receiving conflicting information about the position of your accelerator pedal. This can lead to trouble driving and prompt your Check Engine Light to turn on as a warning.

The accelerator pedal position sensor is located inside the accelerator pedal. In some cases, it is possible to replace just the sensor – but on other car models, you have to replace the whole accelerator pedal.

What is p1128 code?

Code p1128 refers to “Closed loop fueling not achieved“, meaning that for some reason the engine is not reaching a state where it is able to run using the information from the engine sensors.
