Code P0117 GMC Description
The P0117 GMC code indicates that there is a problem with the engine coolant temperature circuit, specifically a low input signal. The engine coolant temperature sensor is responsible for monitoring the temperature of the engine coolant and sending this information to the engine control module (ECM). The ECM uses this data to adjust fuel delivery and ignition timing to ensure optimal engine performance.
Common Causes of P0117 GMC
- Faulty engine coolant temperature sensor
- Corroded or damaged wiring in the coolant temperature circuit
- ECM malfunction
- Low coolant levels
- Cooling system issues such as a stuck thermostat or a malfunctioning radiator fan
Symptoms of P0117 GMC
- Check Engine Light is illuminated on the dashboard
- Engine running hotter or colder than normal
- Poor fuel economy
- Rough idling or stalling
- Difficulty starting the engine
How to Fix P0117 GMC
- Begin by diagnosing the specific cause of the low input signal using a scan tool to read the engine coolant temperature sensor data.
- Inspect the engine coolant temperature sensor and its wiring for any signs of damage or corrosion. Replace the sensor if necessary.
- Check the coolant levels and inspect the cooling system components for any issues that could be affecting temperature readings.
- Clear the diagnostic trouble codes from the ECM and test drive the vehicle to ensure that the issue has been resolved.
- If the problem persists, further diagnostic testing may be required to identify any underlying issues with the ECM or other related components.
Cost to Fix P0117 GMC
The typical repair costs for addressing a P0117 GMC code can vary depending on the specific cause of the issue. In general, replacing a faulty engine coolant temperature sensor can cost between $50 and $150 for the part, with additional labor costs ranging from $50 to $150.
