The 5V reference issue is confirmed by the low voltage at both the pedal and throttle body.
Pin 24 on the MSV80 DME is one of the 5V supply pins for the accelerator pedal module.
Test:
Ignition ON, engine OFF:
1. Disconnect the accelerator pedal.
2. Measure voltage at DME pin 24 → expect ~5V.
3. Reconnect the pedal and re-measure pin 24.
- Voltage drops to ~1V at the DME? Likely DME internal fault or harness short to ground.
- Voltage stays ~5V at DME but drops at pedal? Wiring issue between DME and pedal.
Please report the voltages from both steps.
Inspect DME connectors for corrosion or bent pins in the meantime.
Let me know the results.
