Thread: Trouble History With Camshaft Position Sensor

I had a diagram somewhere that showed the layout of the CPS and its signals. All of them, if I remember correctly went directly to the Ignition Control Module, then from there to the PCM. I'll see if I can dig it up.

What made it odd is that the CPS and Cam sensor operated off 10vdc which was really weird and I couldnt figure out how they were stepping that down from the normal system voltage until I saw it went through the ICM which apparently is providing some voltage regulation. But there are two distinct signals provided by the CPS triggered by the interrupters on the back of the harmnonic balancer.

Good to know. I never really looked into it. And since you looked at the diagrams, I will take your word for it.
