How To Test Temp Sensor With Multimeter

Plug the red probe into the vω port.

How to test temp sensor with multimeter. Every make and model uses a specific temperature sensor which will give you specific readings whenever you test them with a multimeter. You should have a reading of approximately 2000 ohms. Plug the black probe into the com common port on your multimeter. Look online for the hot and cold readings of your vehicle s temperature sensor and compare your readings to see if they closely match.

We ll start with a multimeter continuity test. Connect the black lead of the meter to the body of the cold sensor and the red to the terminal. You should see a much lower reading on the. 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.

Check the warm sensor in your engine. Disconnect the wires for the sensor at its power source point a in the diagram.
