It is easier and cheaper to replace the temperature sensor--try that first
get a new temperature sensor.
seriously? it tells you what temperature you engine coolant/antifreeze is. that is how your gauge on the dash knows what your temperature is at.
The coolant fan sensor is the same as the sensor that shows the coolant temperature on the dash gauge. It is located on the intake manifold.
Most likely a bad sensor/relay
temp sensor - sends signals to the computer for driveability temp sender - measures temp and sends to gauge in dash
There is a coolant temperature sensor and a temperature gauge sensor. the coolant sensor is located on driver side of the cylinder head. screws right into it, and the temperature gauge sensor is on the front side of the cylinder head right under the distributor. hope this helps
usually on the left of the engine between the first two spark plugs
Defective temperature gauge or defective temperature sensor?
It does not have a coolant sensor, But it does have a temperature gauge sensor and you can find it screewed into the driverside head between the first 2 spark plugs up front,
Your engine coolant temperature gauge has a sensor ( there is also a engine coolant temperature sensor that is used for the computer / PCM )
Where is the engin temperature gauge sensor located on the 1999 cadillac catera?
They don't have fuses. The speedometer is controlled by the speed sensor(s) and the temperature gauge is controlled by the coolant temperature sensor.
