Hello all, I just got an 89 K3500 with the 7.4L engine and "3 speed" manual. Overall it's in good shape and I'm working through various small issues. I've gotten a lot of great info from this forum and I hope you can help me here.
I came across a sensor laying on top of the passenger side of the intake manifold and can't identify it. The sensor is beat up, only number is 6165 molded into the connector. It is connected to a single wire I'd call green.
There are no check engine lights or stored codes and the truck runs fine. It's pretty rich at idle but the temp here was 3 degrees last night so I don't expect great cold start performance.
I've attached a picture. Can anyone tell me what this might be? The business end you can't see in the picture is just a metal disc 5/8 inch diameter.
