P1125
TP Sensor Intermittent
2002-2005 Ford Explorer 4.6L V8
Moderate SeverityPowertrain
Description
The Throttle Position sensor signal is intermittent. The PCM detects signal dropouts or erratic voltage changes from the TP sensor.
Symptoms
- Check Engine Light
- Intermittent stumble
- Surging
- Erratic idle
- Stalling
Common Causes
- Worn TP sensor with dead spots
- Loose TP sensor connector
- Damaged wiring
- Corroded connector pins
Diagnostic Steps
- Monitor TP sensor voltage while slowly opening throttle — look for dropouts
- Wiggle test connector while monitoring
- Inspect connector pins
- Test wiring continuity
Repair Notes
Replace TP sensor if it has dead spots. Repair wiring or connector.
