Common causes
- High likelihood: Signal wire shorted to supply
- Medium likelihood: Sensor ground open
- Low likelihood: Connector pins corroded - high contact resistance
Possible symptoms
- Check engine light on
- Reduced throttle response, possible limp mode
- Hesitation or surging
- Idle too high or too low
