P2138 - Pedal to the Truth

P2138 – Accelerator Pedal Position Sensor Correlation Fault explained through music . This rock/pop diagnostic song breaks down fault code P2138, showing how the ECU compares Accelerator Pedal Position Sensor 1 and Sensor 2, what values you should expect, and how to test the circuit correctly before replacing parts. In this video you’ll learn: What fault code P2138 actually means How dual APP sensors work (APP1 & APP2) Typical voltage values at rest and wide open throttle Why one signal rises while the other falls How the ECU detects a correlation mismatch How to test using live data, a multimeter, and an oscilloscope Common causes: worn pedal sensors, wiring faults, poor grounds This song is designed for: Apprentice mechanics Automotive technicians Automotive students Anyone learning real-world vehicle diagnostics 🎵 Music + diagnostics to make learning fault codes easier to remember. 🔧 Key Diagnostic Info 5V reference and sensor ground APP sensor redundancy and safety logic Common codes: P2138, P0120, P0220 Key on engine off testing Correlation monitoring by the ECU 📌 Disclaimer This video is for educational purposes only.
