OBD II P0119
Fault Code Definition
Engine Coolant Temperature Circuit Intermittent
What does Mean?The Engine Coolant Temperature Sensor measures the rise and fall of the Engine Coolant Temperature. This provides critical data needed for the Powertrain Control Module (PCM) to control the Air Fuel Ratio, the Ignition Spark Timing, the cooling fans, and many components of the Emissions Control Systems. The Engine Coolant Temperature Sensor converts the coolant temperature into a voltage that is high when the engine is cold and low as the engine warms up. Code P0119 indicates an intermittent voltage input from the Coolant Temperature Circuit to the PCM.
