P111E 2017 Chevrolet Silverado Code - Engine Coolant Temperature Sensor Not Plausible
Quick Answer
The Engine Coolant Temperature (ECT) sensor is a variable resistor that measures the temperature of the engine coolant. Common causes include Faulty Engine Coolant Temperature (ECT) Sensor, Engine Coolant Temperature Sensor harness is open or shorted, Engine Coolant Temperature Sensor circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P111E 2017 Chevrolet Silverado Description
The purpose of this diagnostic is to determine if the input from the ECT sensor is skewed warmer or colder than the Intake Air Temperature (IAT) sensor and Radiator Coolant Temperature (RCT) sensor. The internal clock of the ECM will record the amount of time the engine is OFF. If the required engine OFF time is met at start-up, the ECM will compare temperatures between the ECT, IAT, and RCT sensors.
If the ECM detects that the temperature difference between the ECT, IAT, and RCT sensors is not within an acceptable operating range, the ECM will continue to run this diagnostic to determine if a block heater was active during the engine OFF time. The Diagnostic Trouble Code (DTC) will be set if the ECM detects that there is a temperature difference between the start-up Engine Coolant Temperature sensor, Intake Air Temperature sensor, and the Radiator Coolant Temperature (RCT) sensor.
What are the Possible Causes of the DTC P111E 2017 Chevrolet Silverado?
- Faulty Engine Coolant Temperature (ECT) Sensor
- Engine Coolant Temperature Sensor harness is open or shorted
- Engine Coolant Temperature Sensor circuit poor electrical connection
- Faulty Engine Control Module (ECM)

2. What are the common symptoms of the P111E code in a 2017 Chevrolet Silverado?
Symptoms may include an illuminated check engine light, erratic temperature gauge readings, poor engine performance, or difficulty starting the engine.
3. What causes the P111E code to appear on a Chevrolet Silverado?
Common causes include a faulty ECT sensor, damaged sensor wiring, corroded electrical connections, or issues with the engine control module (ECM).
4. How do I diagnose the P111E code on my 2017 Chevrolet Silverado?
Start by scanning for codes, inspecting the ECT sensor and wiring for damage or corrosion, checking for proper sensor voltage, and verifying readings with a diagnostic scanner.
5. Can I drive my 2017 Chevrolet Silverado with the P111E code?
Driving with this code is not recommended, as it can cause engine performance issues and lead to potential overheating or other damage.
6. How do I fix the P111E code on a Chevrolet Silverado?
Repairs may include replacing the ECT sensor, repairing or replacing damaged wiring, cleaning corroded connectors, or reprogramming the ECM if necessary.
7. How much does it cost to fix the P111E code in a 2017 Chevrolet Silverado?
Repair costs can range from $50 to $300 or more, depending on whether the issue is a simple sensor replacement or involves more extensive wiring or ECM repairs.
8. Can a faulty thermostat cause the P111E code on a Chevrolet Silverado?
Yes, a stuck open or closed thermostat can affect coolant temperature readings and potentially trigger the P111E code.
9. How do I reset the P111E code after repairs on my Silverado?
After completing repairs, clear the code with an OBDII scanner and test drive the vehicle to ensure the issue is resolved.
10. Could the P111E code be caused by low coolant levels?
Yes, low coolant levels can cause erratic temperature sensor readings and potentially trigger the P111E code. Always check and maintain proper coolant levels.
