P1114
ECT Sensor Circuit Intermittent Low Voltage
2002-2009 GMC Envoy 4.2L I6
Moderate SeverityPowertrain
Description
The PCM detected intermittent low voltage on the Engine Coolant Temperature sensor circuit, indicating the sensor is sporadically reporting very high temperatures.
Symptoms
- Check Engine Light
- Intermittent cooling fan operation
- Incorrect temperature gauge readings
- Erratic idle
Common Causes
- Intermittent short in ECT sensor wiring
- Faulty ECT sensor
- Corroded connector
- Water intrusion
Diagnostic Steps
- Monitor ECT readings for erratic behavior
- Wiggle test ECT connector
- Test sensor resistance
- Inspect wiring for shorts
Repair Notes
Replace ECT sensor or repair wiring as needed.
