Ignition Knock Sensor

Ignition Knock Sensor

work truck that I bought used from a farmer's coop. A bad knock sensor was one of the problems.

Unfortunately, the knock sensor is in the middle of GM's Gen IV V8 smallblock. This wouldn't be so bad if the factory had actually sealed the area around the knock sensor. But the Canadian plant did not and allowed any water that ended up under the hood to pool over the knock sensors. The obvious result? It rusts and stops working which throws up the check engine light. And you have to take off the intake manifold to get at it.

When you go through that much effort, and don't know if it works until everything is put back into place, you don't want any possible problems. So you want things like having both sensors being uniform and from the same company so the computer doesn't get messed up.

But when I ordered two (there are two in every engine), Ignition Knock Sensor I recieved two knock sensors made from different companies in different boxes. Only one was delphi, the other was an off brand. It ended up working, but it is not the situation I wanted to be in.
