What does p0117 mean on the coolant temperature sensor?
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 P0117 indicates a low voltage input from the Coolant Temperature Circuit to the PCM.
What is the error code for engine coolant temperature?
Error Code P0117: Engine Coolant Temperature (ECT) Sensor Circuit Low Input. Error Code P0117 is described as Engine Coolant Temperature (ECT) Sensor Circuit Low Input. Meaning, the PCM (powertrain control module, also referred as ECM or engine control module) determined the ECT sensor output going less than 0.14V or above 284˚ F (140˚ C).
What is the purpose of the p0117 ECT code?
P0117 ECT (Engine Coolant Temperature) Sensor Circuit Low Voltage: The purpose of this code is as a diagnostic check for a resistance corresponding to a very high engine coolant temperature. The check is enabled whenever the engine computer ECM (Engine Control Module) or PCM (Powertrain Control Module) is powered.
What happens when the coolant temperature sensor is low?
When the engine is cold, the resistance is high. When the engine is warm, the resistance is low. If the PCM detects a signal voltage lower than the normal operating range of the sensor then P0117 code will set. An example of an Engine Coolant Temperature ECT sensor Potential symptoms include:
