Check to make sure that the temperature sensor is good. A bad sensor is commonly the cause of the temperature gauge not working.
how do you check the abs sensor on a 1998 contour
OHM meter
When my check engine light comes on, it is caused by the temperature sensor not working. As soon as the light comes on, my temperature drops to cool. If the light goes out, the temp gauge returns to normal.
check the power to gauge and the temperature sensor (tps). if no power broken wire or short to ground. if power to both areas bad gauge.
How can I check the ENGINE COOLANT TEMPERATURE (ECT) sensor on my 1991 HONDA PRELUDE SI 2.1L
if you disconnect the o2 sensor cable in the air intake then start the engine you would see the check engine sign turned on in the gauge panel. It is on then the sensor is working if off the the sensor may have problems
A faulty temperature sensor, a wiring issue, or a blown fuse could cause a temperature gauge to stop working. It could also be due to a malfunction in the gauge itself.
It is possible that the temperature gauge has stopped working in a 1992 Tempo due to a blown fuse. It is also possible that the temperature gauge stopped working do to the temperature sensor in the engine having a short.
Temp. sensor my have stopped working. Quick and fairly easy fix.
It sounds like a bad Temperature Sensor or the Gage It's self.
