    Where is the Temp Sensor located?

    May this will help. Both senors are tied into the same light and buzzer. The wire to the oil temp senor runs behind the starter and can get pinched by the starter and cause a false alarm.

    It depends on which oil temp sensor you are looking for. On an EFI engine there could be two oil temp sensors. The oil temp sensor that the computer uses to know when the engine is at operating temp is right next to the oil filter either on the oil cooler or the adapter for the oil cooler. There could be a second oil temp sensor at the bottom side of the oil pan where a drain plug would normally go. That one will set off an alarm if the oil gets too hot. If you're having a runability problem then you are looking for the oil temp sensor by the oil filter.
