    Question Water Temp Sensor question

    Should I be able to measure some resistance on the water temp sensor when I hook up a mutimeter directly to the sensor?

    I'm trying to diagnose whether the wires are bad or if the sensor is bad. I replaced the sensor about 3 years ago but I am experiencing a hot start problem. I followed the circuit tests from the EFI bible and did not get the desired results when testing the water temp sensor. Any help would be appreciated. Thanks

    Sounds like the sensor went bad. If it's not reading the way it should it needs to be replaced.

    Check for continuity. There should be none when the engine is cold and and it should increase to full continuity as the engine warms up.
