I opened my hood today to check the fluids and noticed the top of my new serpentine belt was scuffed up. Found a unplugged wire managed to get caught between water pump pulley and belt which scuffed the belt and ground down the electrical connection as per the picture. I checked my entire engine in front and don’t see any unplugged sensors. As you can see from picture, the wire comes out a plastic sleeve with 2 wire connectors. 1 of the wires goes to the air pump valve. The other is the one that’s disconnected. Can anyone with an 89 or 88 take a look at theirs and let me know. Only thing I can think of is that my car as per door sticker was built 8/88 and this unplugged connector went to that thermo switch that activates that 9th fuel injector during cold start which the 89’s don’t have. I have no check engine light on so I doubt a sensor is disconnected. The wire connector is a 2 wire plug- Pink with a black stripe, the other wire is Black with a pink or purple stripe.
No idea either. Hoping someone with an 89 can take a pic of their engine. My EGR solenoid has the wire attached to it. I can’t see if I have a sensor under the plenum in front near throttle body.
I think this car might be missing an Air Divert Valve. I only have 1, maybe there should be 2. I got an 88 Corvette shop manual and those color wires is for this valve. Can anyone with an 89 see if there are 2 Air Divert Valve next to each other.
