How to test temp sensor with multimeter.

If you have a new sensor on hand and want to check it you can do this easy test. Check the warm sensor in your engine. Plug the red probe into the vω port. You should have a reading of approximately 2000 ohms.

Disconnect the wires for the sensor at its power source point a in the diagram. We ll start with a multimeter continuity test. Step 4 check with cold sensor. Every make and model uses a specific temperature sensor which will give you specific readings whenever you test them with a multimeter.

To do this use your multimeter to measure the coolant temperature sensor s resistance value and then follow that up by connecting your multimeter s leads on one of the sensors of the electrical connector terminal and consequently the other lead on a different terminal on the electrical connector s sensor. You should see a much lower reading on the.
