I'm replacing the engine in my 89 cherokee 4.0l and there are two sensors on the drivers side by the engine mount that i can't figure out what they are. one is just above the oil pan and behind the engine mount. The next one is directly under the engine mount. I went to the auto parts stores and they couldnt help. I looked on my other two jeeps for any part numbers but they didnt have anything. I'm trying not to go to the dealer my last time there was just :mad: . any ideas
