Throttle/Pedal Position Sensor/Switch E/F Voltage Correlation

on 2025 GMC Canyon AT4X 2.7L I4 Turbo · 4WD

What this code means

The E and F pedal or throttle position sensor signals do not agree with each other. The PCM sees a mismatch between the two redundant channels.

Symptoms

  • Check engine light on
  • Reduced power / limp mode
  • Erratic acceleration

Common causes

  • Faulty accelerator pedal position sensor assembly
  • Wiring fault in E or F circuit
  • Poor connector contact
  • PCM signal processing fault

Diagnostic steps

  1. Scan and compare E and F sensor values
  2. Inspect shared wiring and connectors
  3. Wiggle-test harness for intermittent faults
  4. Replace pedal sensor assembly if signals mismatch
