P0119 2016 Chevrolet Silverado Code - Engine Coolant Temperature Circuit Intermittent
Quick Answer
The P0119 code for a 2016 Chevrolet Silverado indicates an issue with the Engine Coolant Temperature (ECT) Circuit being intermittent. Common causes include Faulty ECT Sensor: The ECT sensor itself may be malfunctioning, causing it to send incorrect temperature readings to the ECM, Damaged Wiring or Connectors: Wiring or connectors in the ECT circuit may be damaged, leading to intermittent connectivity and inaccurate readings, Malfunctioning ECM: The ECM, which receives and processes the ECT sensor data, may be faulty and unable to interpret the signals correctly. 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 P0119 2016 Chevrolet Silverado Description
The P0119 code for a 2016 Chevrolet Silverado indicates an issue with the Engine Coolant Temperature (ECT) Circuit being intermittent. The ECT sensor is responsible for monitoring the temperature of the engine coolant and sending this information to the engine control module (ECM). This data is crucial for the ECM to adjust fuel delivery and ignition timing to ensure optimal engine performance and efficiency. When the ECT circuit is intermittent, it means that there is a problem with the sensor or the wiring that is causing inconsistent readings to be sent to the ECM.
Common Causes of P0119 2016 Chevrolet Silverado
- Faulty ECT Sensor: The ECT sensor itself may be malfunctioning, causing it to send incorrect temperature readings to the ECM.
- Damaged Wiring or Connectors: Wiring or connectors in the ECT circuit may be damaged, leading to intermittent connectivity and inaccurate readings.
- Malfunctioning ECM: The ECM, which receives and processes the ECT sensor data, may be faulty and unable to interpret the signals correctly.
- Cooling System Issues: Problems with the vehicle's cooling system, such as low coolant levels or a malfunctioning thermostat, can impact the ECT sensor readings.
- Corrosion or Contamination: Corrosion or contamination in the ECT sensor or circuit can also cause intermittent issues with temperature readings.
Symptoms of P0119 2016 Chevrolet Silverado
- Check Engine Light: The most common symptom associated with the P0119 code is the illumination of the check engine light on the vehicle's dashboard.
- Engine Performance Issues: The engine may experience rough idling, stalling, or hesitation during acceleration due to incorrect fuel delivery and ignition timing.
- Poor Fuel Efficiency: Incorrect temperature readings can lead to inefficient fuel delivery, resulting in decreased fuel efficiency.
- Overheating: If the ECT sensor is sending inaccurate readings, the engine may overheat due to improper cooling system operation.
- Cooling Fan Operation: The cooling fan may not activate when needed, leading to potential overheating issues.
How to Fix P0119 2016 Chevrolet Silverado
- Diagnose the Issue: Use a diagnostic scanner to retrieve the trouble code and perform a thorough inspection of the ECT sensor, wiring, and connectors to identify the root cause of the problem.
- Replace ECT Sensor: If the ECT sensor is determined to be faulty, replace it with a new sensor to ensure accurate temperature readings.
- Repair Wiring or Connectors: Repair or replace any damaged wiring or connectors in the ECT circuit to restore proper connectivity and eliminate intermittent issues.
- Check ECM Functionality: Test the ECM to ensure it is functioning correctly and interpreting the ECT sensor data accurately. Replace the ECM if necessary.
- Verify Cooling System Operation: Check the cooling system components, such as the coolant level and thermostat, to ensure proper operation and prevent future ECT sensor issues.
Cost to Fix P0119 2016 Chevrolet Silverado
The typical repair costs for addressing a P0119 code on a 2016 Chevrolet Silverado can range from $100 to $300, depending on the specific cause of the issue and the cost of parts and labor in your area. This estimate includes the cost of a new ECT sensor, potential wiring repairs, and diagnostic labor. Keep in mind that the actual cost may vary based on the location of the repair shop, the make and model of the vehicle, and any additional repairs or parts needed. It's recommended to consult with a certified mechanic or auto repair shop for a more accurate cost estimate based on your specific situation.
