Oil Temperature Sensor

watp · Aug 30, 2022

I have a 2014 Jeep Cherokee with 3.2 v6 engine. A code P0197 popped up and I replaced the oil temperature sensor with one from NAPA auto parts. The new sensor worked fine for about 10 minutes and then it stopped showing temperature and set code again. I thought that maybe it was because I used an aftermarket part so I ordered one from local Jeep dealership and installed it last night and the jeep is still showing no oil temperature and set code P0197. This is not a fun job as the sensor is in oil filter housing under the intake! What else could it be? Since this started the engine revs up pretty high when I start it then it runs fine, but still no oil temp.

I found the problem. I peeled back some of the heat wrap on the connector and found the insulation was missing and the bare wires were touching. I repaired the wires and now everything works normally. I hope this helps someone if they ever encounter a similar issue.

Hey Keith,

Are you saying your sensor is reporting 300 degrees on the oil? If so, which engine (3.2V6 or 2.4 I4?). May want to also post over on JeepCherokeeClub.com. Very active Forum. BTW, if you have the 2.4 engine, check your oil level - the MultiAir unit is dependent on high pressure oil to work the solenoids. If it's low, the engine will shut down due to the solenoids not being able to open the intake valves.
