Document table of contents
- Circuit Description — Hall effect accelerator pedal position sensor operation and 5-volt supply
- Component Location
- Reason — SPN 91 / FMI 4, PID P091, voltage below normal or shorted to low source
- Effect — Engine operates in Limp Home mode
- Conditions for Running the Diagnostics
- Conditions for Setting the Fault Code — Signal voltage less than 0.826 VDC for more than 1 second
- Action Taken When the Fault Code Is Active — Red STOP ENGINE lamp and MIL illumination
- Conditions for Clearing the Fault Code
- Shop Talk — Dual vs. single throttle position sensor pedals, intermittent fault guidance
- Troubleshooting Steps 1A–1B: Check for sensor supply fault codes 2185/2186 and active status
- Step 2A: Inspect accelerator pedal position sensor and connector pins
- Steps 2B–2D: Verify 4.75–5.25 VDC supply voltage, circuit response with jumper wire, pedal condition
- Step 3A: Inspect ECM and OEM harness connector pins
- Steps 3B–3C: Check for open circuits in supply and signal lines (resistance less than 10 ohms)
- Steps 3D–3E: Check for pin-to-pin and pin-to-ground short circuits (resistance greater than 100k ohms)
- Step 3F: Check for inactive fault code after reconnection
- Step 4A: Verify ECM calibration update availability
- Step 4B: Disable and clear the fault code, verify repair completion
