P0119 2014 Chevrolet Silverado Code - Engine Coolant Temperature Circuit Intermittent
Quick Answer
The Engine Coolant Temperature (ECT) sensor is a variable resistor that measures the temperature of the engine coolant. Common causes include Low engine coolant level, Leaking or stuck open thermostat, Faulty Engine Coolant Temperature (ECT) sensor. 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 2014 Chevrolet Silverado Description
The ECM uses this high side coolant rationality diagnostic to determine if the input from the ECT sensor is skewed warmer than normal. The internal clock of the ECM will record the amount of time the ignition is OFF. If the calibrated ignition OFF time is met at start-up, the ECM will compare the temperature difference between the ECT and the intake air temperature (IAT) to determine if the temperatures are within an acceptable operating range of each other. The Diagnostic Trouble Code (DTC) will be set when the ECM detects a the ECT is Intermittent for greater than 3 s.
What are the Possible Causes of the DTC P0119 2014 Chevrolet Silverado?
- Low engine coolant level
- Leaking or stuck open thermostat
- Faulty Engine Coolant Temperature (ECT) sensor
- Engine Coolant Temperature sensor harness is open or shorted
- Engine Coolant Temperature sensor electrical circuit poor connection
- Faulty Engine Control Module (ECM)

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.
