New sensor did not work what next?

Question

Sensors are good but am still getting p0342 camshaft code. Not sure how to test signal wire but ground and positive are good.

HI there

You need a scope to check the output from the sensor. It's basically a wave pattern. I would check the timing. If the timing is off a couple of teeth then it is going to continue to throw a code for the cam sensor. This could be the cause of the problem. Here is some more info

Thanks for your reply much appreciated but after I pulled the mount and cover off I found about 1/4 of the timing teeth missing. Should have started there but it ran well right before I parked it and now after two weeks since purchased I have a valve or two stuck and maybe more but haven't got that far. The original owner said the timing was done not too long ago but I could peel teeth right off the belt and have never seen such rusty spark plugs on a newer car like this. Should have had it inspected but I had a little faith in the honor code and it bit me.
