KStretch55 Posted June 7, 2005 Share Posted June 7, 2005 My 92 Loyale wagon seems to have an intermittant temp guage. Works fine most of the time, but now and then it just goes dead for a while. I know the coolant is topped off and everything is running fine. I think it might be the sensor. Is the sensor that runs the guage the one in the thermostat housing, that normally has a green connector on the wire pigtail? Thanks Quote Link to comment Share on other sites More sharing options...
hooziewhatsit Posted June 7, 2005 Share Posted June 7, 2005 the coolant sensor with the green pigtail is for the computer. The sensor for the gauge in the dash is the one with a single plug. I'd guess that the connection there is just corroded and needs to be cleaned. After that, you can start doing continuity tests on the wire to ground. When it goes dead, I assume it goes to the cold end? If so, there must be problem in the dash itself, as if the sensor wire was grounded, it would go to the HOT end.

Bill90Loyale Posted June 7, 2005 Share Posted June 7, 2005 That's it. There are two others: the "coolant temp sensor" (which talks to the ECU) mounted directly into the intake manifold, and the "thermoswitch" on the radiator (which turns the radiator fan on and off).
