Help with testing coolant temp sensor
I have reason to believe it is malfunctioning.
I have a 2001 LC accent with the 1.5 SOHC and no A/C. If I'm looking at this right, the coolant temp sensor is on the thermostat housing, and based on it's readings, determines whether the radiator fans turns on or not.
Well, the fan hasn't been turning on so I've been running hot. I tested the fan and it works.
I've searched HMA service and couldn't find a testing procedure for the sensor. I looked and there are three contacts on the sensor that plug into blue, orange, and black wires on the harness.
How do I test to see if it's working correctly? Am I measuring resistance or voltage, and on which pins? Anybody have any wisdom on this? Like right now? (the hood is up and I need to know asap... =)
