There is a plug/sensor on my 1990 ZR1 corvette that seems to be leaking oil. The sensor is brittle from age and the white plug does not seal when plugged in. It's located on the passenger side of the throttle body next to the serpentine belt. I don't know exactly what this is for and thus don't know what part(s) to search for. If someone can tell me anything they know about this I would really appreciate it.

Richiesredvette,

You are a lucky man. I don’t know if it is 90 set up but typically these sensors point down I’d an awkward angle making it very difficult to remove. Yours looks like it is mounted on a 90 degree elbow and a breeze to remove.

Oh! It’s the larger one on top. Ok. I understand now. Thanks Jerry for straightening me out. I got confused with low pressure warning switch.
