Code P111E 2014 GMC Sierra Description
The P111E diagnostic trouble code (DTC) for a 2014 GMC Sierra indicates that the Engine Coolant Temperature Sensor is not providing plausible data to the engine control module (ECM). The Engine Coolant Temperature Sensor is a crucial component that measures the temperature of the engine coolant. This information is used by the ECM to adjust fuel delivery, ignition timing, and other engine parameters to ensure optimal performance and efficiency. When the sensor is not providing accurate data, it can lead to various issues with the vehicle's performance.
Common Causes of P111E 2014 GMC Sierra
- Faulty Engine Coolant Temperature Sensor.
- Wiring issues or corrosion in the sensor circuit.
- ECM malfunction.
- Coolant leak affecting sensor readings.
- Sensor placement or mounting issues.
Symptoms of P111E 2014 GMC Sierra
- Check engine light illuminated on the dashboard.
- Poor fuel economy.
- Rough idling or stalling.
- Engine overheating.
- Inaccurate temperature gauge readings.
How to Fix P111E 2014 GMC Sierra
- Begin by diagnosing the issue using a scan tool to confirm the P111E code and pinpoint the exact cause of the problem.
- Inspect the wiring and connections related to the Engine Coolant Temperature Sensor for any damage or corrosion. Repair or replace as necessary.
- Test the sensor itself for proper functionality. If faulty, replace the sensor with a new one.
- Clear the DTC from the ECM memory using the scan tool and test drive the vehicle to ensure the issue has been resolved.
- Monitor the engine coolant temperature readings to verify that they are now accurate.
Cost to Fix P111E 2014 GMC Sierra

Frequently Asked Questions about P111E 2014 GMC Sierra Code
1. What does the OBDII code P111E mean on a 2014 GMC Sierra?
The P111E code indicates an "Engine Coolant Temperature Sensor Not Plausible," meaning the sensor is providing data that doesn't match expected values.
2. What are the common symptoms of the P111E code?
Symptoms may include the check engine light turning on, poor engine performance, incorrect temperature readings, or the engine running too hot or cold.
3. What causes the P111E code to appear on a GMC Sierra?
Common causes include a faulty engine coolant temperature sensor, wiring issues, a bad thermostat, or a problem with the engine control module (ECM).
4. Can I drive my 2014 GMC Sierra with the P111E code?
Driving with this code is not recommended, as it can lead to overheating, poor fuel efficiency, and potential engine damage.
5. How do I diagnose the P111E code on my GMC Sierra?
Use an OBDII scanner to confirm the code, inspect the engine coolant temperature sensor and its wiring for damage, and verify the thermostat's function.
6. How do I fix the P111E code on a 2014 GMC Sierra?
Repairs often include replacing the coolant temperature sensor, fixing damaged wiring, or replacing a stuck thermostat. In rare cases, the ECM may need reprogramming or replacement.
7. How much does it cost to fix the P111E code on a GMC Sierra?
Costs vary, but replacing the coolant temperature sensor typically ranges from $100 to $300, depending on labor and parts.
8. Can a bad thermostat trigger the P111E code?
Yes, a thermostat stuck open or closed can cause temperature readings that the ECM finds implausible, triggering this code.
9. How does the coolant temperature sensor affect engine performance?
The sensor provides data to the ECM to manage fuel injection and engine timing. Incorrect readings can lead to poor performance and inefficiency.
10. Will clearing the P111E code with a scanner fix the problem?
Clearing the code may temporarily turn off the check engine light, but the underlying issue must be repaired to prevent the code from returning.
