i have a 95 camry v6 w/170000 miles. about 3 weeks ago my tempature gaurge isn’t working. I like to know what causes the temp gaurge to stop working
Low coolant, bad gauge, or bad temp sending unit; usually the latter. Turn the key to the RUN position, ground the temp sender wire lead to bare metal, and the gauge should read full HOT. If it does, the sender is bad.
This sender is not the same thing as the engine coolant temp sensor for the emissions/fuel injection.
And if it just stays on the low end, it could be the thermostat’s stuck open. Are you getting good heat?
