I'm trying to track down a temperature issue on our 2.0L, and have replaced the gauge and sender. Temp still goes to red (about 280F), within 10 minutes of driving. Temp is actually around 165F from a laser temp reader. Only thing I can think of is wiring.
Am I correct, when I see the wiring diagram showing the Oil temp indicator is the same as the sensor? The diagram shows an "indicator" and a "gauge". I want to run some external, new wires to see if there's a difference. Thanks for any knowledge.  |

seems very odd, wish I could be of assistance, but I have never ran across this. I use a laser temp sensor often and found them more or less accurate |
