Pontiac G5 Coolant Temperature Sensor Parts Questions & Experts Answers
- Q: What Is the Function and Troubleshooting Process of the Coolant Temperature Indicator System and Coolant Temperature Sending Unit on Chevrolet Cobalt,HHR,Saturn ION and Pontiac G5?A: The coolant temperature system includes a dashboard warning light or gauge, and an engine coolant temperature (ECT) sensor. It also works as the coolant temperature-sending unit for the Powertrain Control Module (PCM). If overheating is indicated, check the coolant level and wiring harness connectors. When the ignition is turned to START, the light should come on, showing the bulb works. If it doesn't, the bulb may be burned out, the ignition switch faulty, or the circuit open. When turning on the engine, the light should go off; if not, the engine is overheating. If it stays on, there could be a grounded wire, a defective sending unit, or a faulty ignition switch. Also, check the coolant mix, as high water content may not activate the sending unit.
