Where is the ECT sensor located in the engine?
The ECT (Engine coolant temperature) sensor is a thermistor located in the engine block or other coolant passage. It changes resistance with changes in temperature of the coolant that it’s in contact with.
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
How can I check the ECT reading on my car?
Having said that here are the possible solutions: Using a scan tool, with KOEO (Key on engine off) check the ECT reading on the display. On a cold engine the ECT reading should match the IAT (Intake Air Temperature) sensor reading. If it doesn’t, replace the ECT sensor.
How does the coolant temperature sensor work on a Nissan?
The modified signal returns to the ECM as the engine coolant temperature input. The sensor uses a thermistor which is sensitive to the change in temperature. The electrical resistance of the thermistor decreases as temperature increases. Need more information on how to fix the P0118 NISSAN code?
