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.

The sensor reads resistance to ground. You may have a short to ground on the sensor wire. I would pull the gauge and hook it up in the engine compartment. The green with stripe sensor wire have a union on the passenger side of the engine compartment. Hook up the gauge there with some jumper wires. If you get the same false hot reading the sensor wire may have worn insulation and shorting to ground. If so string a new one. The original path is in back of the fan shroud.
You would need to drop the engine to use the same routing. I would find an alternate route if needed.
Good luck.
