im trying to figure out what are the two sensors on my moms car, 88 chevy celebrity wagon. It has a 2.8 engine.
There are two sensors on the lower side of the block, opposite side of the starter.
There is one that has a small one inch long shaft with a large circle thing on it, and only one wire going into it. The other, sort of looks like a plastic figure 8 with two wires going into it and it is held down by a small 1/4"? bolt, and two wires are coming out of that one.
I having some oil coming out of someplace near those sensors, its not leaking but just making the block oily. And the manuals i have dont really get into detail about the other sensors besides the oil pressure one.
