Q: water temp gauge doesn't work

asked by on

Where should I look for a problem?

My car has 237000 miles.
My car has an automatic transmission.

The temperature sensor should be tested to see if it is within specifications. If you disconnect the sensor the gauge should go all the way to hot. If you short the sensor wire the gauge will go to cold. This will help you pinpoint the issue with your gauge then replace the sensor as necessary. Good luck.

If you need some assistance with this, contact a certified mechanic who’ll be able to assist you with replacing your temperature sensor.
