Code P0117 2015 Chevrolet Silverado Description
The P0117 code on a 2015 Chevrolet Silverado indicates a problem with the Engine Coolant Temperature (ECT) sensor circuit, specifically a low input signal. The ECT 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 and efficiency.
Common Causes of P0117 2015 Chevrolet Silverado
- Faulty ECT sensor
- Corroded or damaged wiring in the ECT sensor circuit
- Loose or poor connection at the ECT sensor
- ECM software issue
- Coolant level too low to properly register temperature
Symptoms of P0117 2015 Chevrolet Silverado
- Poor fuel economy
- Rough idling or stalling
- Difficulty starting the engine
- Engine overheating
- Check Engine Light illuminated
How to Fix P0117 2015 Chevrolet Silverado
- Begin by visually inspecting the ECT sensor and its wiring for any signs of damage or corrosion.
- Test the ECT sensor using a multimeter to check for proper resistance values.
- Check the wiring harness for continuity and repair any damaged wires.
- If the ECT sensor and wiring are in good condition, test the ECM for proper operation.
- Clear the diagnostic trouble codes and test drive the vehicle to ensure the issue has been resolved.
Cost to Fix P0117 2015 Chevrolet Silverado
