Diagnose and repair dtc p2138 Dtc p2138 stands for “throttle/pedal position sensor/switch d/e voltage correlation.” this code is triggered when the ecm or pcm detects that the signals from the two throttle position. Master multimeter checks, pinpoint wiring issues, and correctly replace the accelerator sensor system.

P2138 means throttle/pedal position sensor/switch d/e voltage correlation
Learn this diagnostic trouble code’s meaning, possible causes, and common symptoms.
Drivers who encounter a p2138 fault quickly notice that the vehicle’s throttle does not behave as expected The check‑engine light illuminates, and a “throttle position sensor” warning may appear on. P2138 code means throttle/pedal position sensor correlation error causing limp mode and poor acceleration Fix p2138 codes fast and save $600+.
If your vehicle is showing a p2138 code, this video explains what it means and how to go about fixing. Symptoms of a p2138 code can range from stalling when you come to a stop, total lack of power, no acceleration, sudden loss of power at cruise speeds or stuck. P2138 indicates a mismatch or correlation error between the voltages of two accelerator pedal position sensors These sensors, often called app sensors.
The most common cause of p2138 (throttle/pedal position sensor/switch d/e voltage correlation.) is
Failed accelerator pedal position (app) sensor assembly Diagnostic trouble code p2138 indicates that a vehicle’s electronic throttle body is not responding as anticipated to ecm/pcm input, as directed via a signal from the accelerator pedal position. How to fix a p2138 code Throttle/pedal position sensor/switch d/e voltage correlation
A p2138 code is set when the ecm/pcm detects that the signals from th. The check‑engine light illuminates, and a. In modern vehicles, the new electronic throttle control technology consists of an accelerator pedal position sensor and an electronically controlled throttle body that pairs with an internal motor. Learn all about the p2138 code, what causes throttle/pedal position sensor voltage correlation issues, and how to diagnose and fix common issues to maintain optimal engine performance.
What is the p2138 code
The throttle position sensor (tps) and the accelerator pedal position (app) sensor (also called the gas pedal sensor) are both potentiometers 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. Find the right diagnostic tools to identify and clear.
The p2138 code, formally defined as “throttle/pedal position sensor/switch ‘d’/’e’ voltage correlation,” signals a significant communication failure within your vehicle’s electronic throttle control.
