[QUOTE="wallypiper, post: 176463, member: 2685"] Strange. After considering that there is a sort of analog display on the dash for coolant temp, I studied the shop manual some more. It seems, at this point, to be somewhat self contradictory. The test for the coolant temperature sensor is clearly a continuity check - above the "ON" point, there should be continuity between the two terminals of the sensor, below the "OFF" point, there should not be continuity. However, there is a section in the "FEATURES" section of the manual which identifies the sensor as a thermistor (a common type of analog temp sensor which has resistance that varies with temperature) and a chart showing what the resistance should be as the temp varies from about -30 to +80 C. So now I'm confused - which is it? A switch like the test procedure implies or a thermistor like the FI operation description says? Are there two sensors? Perhaps you just adjusted the display calibration. [/QUOTE]
