2012 Ford Escape P2138 - App Sensor Voltage Correlation Code Throttle Pedal Position Sensoswitch D E

Author Dalbo 29 May 2026

Diagnose the p2138 code (sensor voltage correlation error) that causes limp mode Dtc p2138 means “throttle/pedal position sensor/switch d/e voltage correlation.” this diagnostic trouble code gets. The p2138 ford diagnostic trouble code (dtc) indicates a correlation issue between the throttle/pedal position sensor and switch 'd'.

P2138 Code: Throttle/Pedal Position SensoSwitch D/E Voltage

2012 Ford Escape P2138 - App Sensor Voltage Correlation Code Throttle Pedal Position Sensoswitch D E

The pcm detects improper voltage correlation between throttle/pedal position sensors d and e What does p2138 code mean These redundant sensor signals should.

P2138 means throttle/pedal position sensor/switch d/e voltage correlation

If the diagnosis confirms that the internal voltage signals of the app sensor are not correlating properly, the entire sensor. P2138 code means throttle/pedal position sensor correlation error causing limp mode and poor acceleration. To fix a p2138 code, you must resolve a voltage correlation discrepancy between the two internal sensors of the accelerator pedal. Code p2138 is commonly caused by a failed tp or app sensor, circuit issues, and problems with the pcm
