So the car wouldn't start. Thought it was the cam or crank sensor so yesterday I took out the cam sensor and cleaned it. Put it back in but forgot to connect the sensor harness to the sensor. The car started right up and ran fine but threw a check engine light. I didn't have time to diagnose right then as I had to go to work. Driving home, the engine started knocking like a pushrod motor. So I opened the hood and realizaed I didn't plug the sensor back in. Problems solved but, isn't the car suppose to not start without the cam sensor? How can this be that I drove it like this?

RE: Interesting

actually the car will start sometimes with a bad cam sensor.

the computer only "peeks" at the sensor on start up to figure out which cylinders are where.

Then.. it remembers the order and goes by memory from there.

I think it's something like it'll mis fire 3 times and the fourth "guess" will run..

or something like that.

Cant remember exactly

IF the car will start it can and will run with a faulty cam sensor. This is why it is usually diagnosed as an intermittent fault. You can start the car and unplug the cam sensor with hardly an issue except possibly throwing a code.
