Where Is Engine Coolant Temperature Ect Sensor Located

Where Is Engine Coolant Temperature Ect Sensor Located Here is everything you need to know about the engine coolant temperature sensor including how it works, what it affects, how to replace it, the symptoms and. The ect sensor is a high authority sensor whenever the engine is cold because ignition timing is tailored according to the engine coolant temperature. it also provides input for idle air control (iac) position, oxygen sensor closed loop status, on off times for the canister purge, and idle speed.

Engine Coolant Temperature Sensor Purpose Location And Failure Signs The engine coolant temperature sensor is typically located near the thermostat housing or on the cylinder head. it is usually a two wire sensor that is either threaded into the engine block or mounted in a coolant passage. if the engine coolant temperature sensor fails, it can cause a variety of problems. Here is a more detailed list of the signs of a bad or failing coolant temperature sensor to look for: 1. check engine light. one of the first signs of all coolant temperature sensor symptoms you will probably notice is that the check engine light will show up on your dashboard. if the computer detects any problem with the sensor’s circuit, it. The engine coolant temperature ( ect) sensor is a variable resistor that measures the temperature of the engine coolant. the powertrain control module ( pcm) supplies 5 volts to the signal circuit. when coolant temperatures are low, resistance is high. when coolant temperatures are high the resistance is low. the pcm uses this input for engine. The main engine coolant temperature sensor is known as the primary ect sensor or ect sensor 1. this sensor is located on the coolant passage next to or in the thermostat housing of the cylinder block or cylinder head. in an internal combustion car’s engine, the cylinder head is placed on the top of the car’s cylinders above the cylinder block.
