How can I tell if my coolant temperature sensor is not working?
How can I tell if my coolant temperature sensor is not working? Check the warm sensor in your engine. You should see a much lower reading on the ohm meter. If not, then it is not working correctly. Replacing the coolant temperature sensor is an easy process that anyone can do at home with some basic mechanic's tools. Can a check engine light get clogged up? The EGR valve can get clogged up or fail entirely. If you’re even slightly mechanically inclined, you can remove the valve, clean it up, and reinstall it in a relatively short amount of time....
