What sensor is this?
87 jeep cherokee, 4.0. There is a sensor on the bottom drivers side of the block. Just above the oil pan about mid way on the block between the front and the back. Any idea what this is?

If t he connector looks like a fuel injector, with the wire clip, its a knock sensor.
If not, just two wore connector its a temp sensor.
