Code P0119 2014 Chevrolet Silverado Description
The P0119 diagnostic trouble code (DTC) for a 2014 Chevrolet Silverado refers to an issue with the Engine Coolant Temperature (ECT) Circuit Intermittent. This code indicates that there is a problem with the circuit that monitors the engine coolant temperature. The ECT sensor is a crucial component that helps the engine control module (ECM) determine the correct fuel mixture and ignition timing for optimal engine performance. When the ECT circuit is intermittent, it means that the signal from the sensor is not consistent, leading to potential issues with engine performance, fuel efficiency, and emissions.
Common Causes of P0119 2014 Chevrolet Silverado
- Faulty ECT Sensor: The most common cause of the P0119 code is a malfunctioning ECT sensor that is sending inconsistent signals to the ECM.
- Wiring Issues: Damaged or corroded wiring connections to the ECT sensor can disrupt the signal and trigger the code.
- ECM Malfunction: A problem with the engine control module (ECM) can also lead to an intermittent ECT circuit code.
- Cooling System Problems: Issues with the cooling system, such as low coolant levels or a malfunctioning thermostat, can affect the ECT sensor readings.
- Electrical Issues: Any electrical problems in the circuit, such as a blown fuse or a faulty relay, can cause the ECT circuit to be intermittent.
Symptoms of P0119 2014 Chevrolet Silverado
- Check Engine Light: The most common symptom associated with the P0119 code is the illumination of the check engine light on the dashboard.
- Engine Overheating: If the ECT sensor is not providing accurate readings, the engine may overheat due to incorrect cooling system operation.
- Poor Fuel Efficiency: A faulty ECT sensor can lead to incorrect fuel mixture adjustments, resulting in decreased fuel efficiency.
- Rough Idle: The engine may experience rough idling or stalling if the ECT circuit is intermittent.
- Difficulty Starting: In some cases, the vehicle may have difficulty starting if the ECT sensor is not functioning properly.
How to Fix P0119 2014 Chevrolet Silverado
- Diagnose the Issue: Use a scan tool to retrieve the trouble codes and perform a thorough inspection of the ECT sensor and related components.
- Test ECT Sensor: Check the ECT sensor's resistance and voltage readings to determine if it is functioning correctly.
- Inspect Wiring: Inspect the wiring harness for any damage, corrosion, or loose connections that may be causing the intermittent circuit.
- Replace ECT Sensor: If the ECT sensor is faulty, replace it with a new one and ensure proper installation.
- Clear Codes: After making the necessary repairs, clear the trouble codes and test drive the vehicle to ensure the issue has been resolved.
Cost to Fix P0119 2014 Chevrolet Silverado
The typical repair costs for addressing a P0119 code on a 2014 Chevrolet Silverado can vary depending on the specific cause of the issue. In general, replacing a faulty ECT sensor can cost between $50 and $150 for the part, with additional labor costs ranging from $80 to $150 per hour. If the problem is related to wiring issues or other components, the repair costs may increase accordingly. It is advisable to consult with a qualified mechanic or auto repair shop to get an accurate estimate based on the specific diagnosis and repair needed for your vehicle. Keep in mind that labor rates can vary based on location, vehicle make and model, and the complexity of the repair.

Frequently Asked Questions about P0119 2014 Chevrolet Silverado Code
What does OBDII code P0119 mean on a 2014 Chevrolet Silverado?
P0119 indicates an intermittent issue in the Engine Coolant Temperature (ECT) sensor circuit, which monitors the coolant temperature and helps the engine control module (ECM) regulate engine performance.
What are the common symptoms of code P0119 in a 2014 Chevrolet Silverado?
Symptoms may include engine overheating, poor fuel economy, difficulty starting, erratic temperature gauge readings, or the check engine light turning on.
What causes the P0119 code to appear on a 2014 Chevrolet Silverado?
Common causes include a faulty ECT sensor, damaged wiring or connectors in the sensor circuit, a stuck thermostat, or a malfunctioning ECM.
Can I drive my 2014 Chevrolet Silverado with a P0119 code?
While the vehicle may still be drivable, it’s not recommended, as unresolved coolant temperature issues can lead to engine overheating or improper fuel mixture, potentially causing further damage.
How do I fix the P0119 code on my 2014 Chevrolet Silverado?
Repairs may involve replacing the ECT sensor, repairing damaged wiring or connectors, flushing and replacing coolant, or replacing a faulty thermostat if needed.
How do I test the ECT sensor for the P0119 code?
You can test the ECT sensor using a multimeter to check the resistance at various temperatures or monitor its signal with an OBDII scanner to ensure it’s sending accurate data to the ECM.
What tools are needed to fix the P0119 code on a 2014 Chevrolet Silverado?
Basic tools include a multimeter, OBDII scanner, coolant system pressure tester, and possibly a socket set for removing the ECT sensor or thermostat.
How much does it cost to repair a P0119 code on a 2014 Chevrolet Silverado?
Repair costs vary but typically range from $50 to $200 for an ECT sensor replacement, while thermostat replacement or wiring repairs could cost more depending on labor rates.
Can a low coolant level trigger the P0119 code?
Yes, low coolant levels can cause erratic temperature readings, which may trigger the P0119 code. Always check and maintain proper coolant levels.
Will clearing the P0119 code solve the problem permanently?
No, clearing the code without addressing the underlying issue will only temporarily turn off the check engine light. The code will likely return until the root cause is fixed.
