What does the p0117 code on the coolant sensor mean?
The engine coolant absorbs heat from the engine, while the sensors monitor its temperature. The P0117 code indicates a problem with one of the engine coolant temperature sensors in your vehicle. Find out more about this error code and what to do in case you encounter it using this short guide.
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 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).
When to replace the coolant temperature sensor 1?
If warmer than 149° C (300° F): Test or replace the Engine Coolant Temperature Sensor. The coolant temperature gauge will display full cold when an ECT DTC sets. After starting the engine, the ECT sensor 1 temperature should rise steadily, then stabilize after the thermostat opens.

What causes an engine coolant sensor to malfunction?
P0117 Possible Causes 1 Low engine coolant level 2 Faulty Engine Coolant Temperature (ECT) sensor 3 Faulty engine coolant thermostat 4 Engine Coolant Temperature (ECT) sensor harness is open or shorted 5 Engine Coolant Temperature (ECT) sensor circuit poor electrical connection
What is the diagnostic code for engine coolant temperature?
Cost of diagnosing the P0117 code. P0117 is a diagnostic trouble code (DTC) for “Engine Coolant Temperature (ECT) Sensor Circuit Low Output Problem”. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation.
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:
How does a coolant temperature ECT sensor work?
As the temperature of the coolant changes, the resistance of the sensor changes. 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
