What is po117?
What is po117?
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 happens to the p0117 code when coolant is warm?
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.
What does the code p0118 mean on a Dodge Caravan?
P0118 is a common OBDII trouble code. It is a general code, which means that it’s going to have the same meaning for the Dodge Caravan as it would any other vehicle. This code is thrown when the resistance coming from the coolant temp sensor does not change as the vehicle warms up. Dodge Caravan P0118 Symptoms.
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 coolant temperature sensor work on Toyota p0118?
The powertrain control module (PCM) provides a 5 volt reference and a ground to the sensor. The PCM monitors voltage drop to determine coolant temperature. If the ECT reads less than freezing temp. when engine has been running for more than a few minutes, the PCM determines a circuit fault and sets this code.
