Doug nothing came up on your post Posted by Saabu [Email] ![]() ![]() In Reply to: Re: Coolant gauge temperature sensor, DougM ![]() ![]() |
Louis,
the NTC sensor sends a signal to the ECU as to the engine temperature. The ECU factors this into engine performance. depending on the coolant temp, the NTC provides more or less resistance, and the ECU reacts.
I think NTC problems generally affect engine idle speed . if you are having that sort of problem and have eliminated the AIC valve and other vacuum-related components, it may be your NTC sensor is shot. You test across the two terminals with an ohmmeter at different engine temperatures to see if it's reacting the correct way.
for a cold engine, my NTC sensor had a low resistance reading so i am replacing it. it should be higher resistance at lower temperatures i believe. if u want more info i've got the Bentley manual and can give you the figures and temperatures.
