There is not one sensor. All the ECM sensors are tied to the check engine light.
Depending on the engine, check coolant relay and temp sensor that triggers that relay
check your fire wall
The check engine light comes on to indicate a possible problem with one of the engine's emission control systems. Take it in for service, and have the vehicle scanned for any trouble codes to locate the problem - usually a sensor.
To check the camshaft sensor on a 1993 Eagle Talon 2.0L engine, first locate the sensor, typically found near the camshaft or cylinder head. Disconnect the electrical connector and use a multimeter to measure the resistance between the sensor terminals; it should fall within the manufacturer's specified range. Additionally, you can check for proper signal output by cranking the engine and observing the voltage at the sensor connector with the multimeter. If the readings are out of range or absent, the sensor may need to be replaced.
To check the camshaft position sensor on a 2002 Suzuki Aerio, first, locate the sensor, which is typically near the camshaft on the engine. Disconnect the electrical connector and use a multimeter to measure the resistance between the sensor terminals; refer to the vehicle’s service manual for the specific resistance values. Additionally, you can check for proper voltage supply to the sensor while the engine is running. If the readings are outside the specified range, the sensor may need replacement.
To install the knock sensor on a 1996 BMW Z3 1.9 engine, first, ensure the engine is cool and disconnect the battery. Locate the knock sensor, which is typically positioned on the engine block near the cylinder head. Remove the old sensor by unscrewing it and disconnecting the electrical connector. Install the new sensor by connecting it and securing it in place, then reconnect the battery and start the engine to check for proper function.
The oxygen sensor is one of many things that could turn the check engine light on.The oxygen sensor is one of many things that could turn the check engine light on.
You locate cam-sensor check for loose or broken wires ,if this doesn't work replace cam-sensor.
That is what the check engine light is for. It informs you of a failure.
The first thing that I would check is the wiring and the temp sensor @ the engine. Sorry but I do not know where the sensor is located on the engine. Usually they are not too hard to locate. i would replace temperature sender usual located near front of engine near thermostat housing
If it is bad the check engine light will come on and set a code for that particular sensor.
Yes, an unplugged sensor can cause a check engine light.
