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
What does the trouble code p2138 stand for?
The automotive trouble code P2138 throttle/pedal position sensor/switch D/E voltage correlation refers to a problem related to the throttle’s ability to open and close properly. In the 1990’s automotive manufacturers began industry-wide installation of “Drive by wire” throttle control technology.
What does the p1238 code on a throttle sensor mean?
Code P1238 indicates that the signals from the two throttle position sensors (or two accelerator pedal position sensors) do not correlate. What Does the P2138 Code Mean?
What to do if your p2138 is intermittent?
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. If it is not, the condition may need to worsen before a diagnosis can be made. Continue to operate the vehicle until the PCM enters readiness mode or the code is reset.
The automotive trouble code P2138 throttle/pedal position sensor/switch D/E voltage correlation refers to a problem related to the throttle’s ability to open and close properly. In the 1990’s automotive manufacturers began industry-wide installation of “Drive by wire” throttle control technology.
What is the diagnostic code for throttle / pedal position sensor?
P2138 is a diagnostic trouble code (DTC) for “Throttle/Pedal Position Sensor/Switch D/E Voltage Correlation”. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation.
Code P1238 indicates that the signals from the two throttle position sensors (or two accelerator pedal position sensors) do not correlate. What Does the P2138 Code Mean?
When to use the p2138 malfunction indicator lamp?
If the two signal inputs vary by more than the acceptable programmed limit, for more than a certain period of time, a code P2138 will be stored and a malfunction indicator lamp (MIL) should be illuminated. In most cases, the PCM will also enter limp in mode. In this mode, engine acceleration will be severely limited if not disabled.
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.
What does the trouble code p2128 stand for?
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. Do NOT assume you have a bad accelerator pedal sensor.
What does the DTC code p2138 stand for?
What Does the P2138 Code Mean? Diagnostic trouble code (DTC) P2138 stands for “Throttle/Pedal Position Sensor/Switch D/E Voltage Correlation.”
