So awhile back I was noticing my temps lightly increasing up to 225-230 degrees in normal city driving......maybe normal and mixed "heavy on the pedal" driving and such. I noticed my eFan wasn't coming on. At 225-230 degrees, the fan should have come on much earlier.....
So I was a lso getting a soft code telling me the engine was "cool too long - replace coolant temp sensor."
My guess is that the coolant temp sensor is fubar......thinking the engine is too cool and making it warm up when it doesn't need to be. That would also explain why the eFan wasn't coming on because it wasn't aware it was that warm.
This is a 95 XJ so the temp gauge sender is seperate from the coo lant temp sender.
Would the heating up of the engine sound like a symptom of a FUBAR coolant temp sensor?
If I stopped the temperature would just stay where it was - around the 225-230 mark, as well.
