2003 Tahoe P0342

[Chevyman95]

Hi can't figure this one out, I have a 03 Tahoe with 220k miles. I got a p0343 code so I replaced the camshaft sensor. Now I have a p0342 code. I replaced the connector wiring and it is still throwing the code on startup. Runs perfectly fine though. When I test voltage I have 11.5v on one and nothing on the other 2. Any suggestions? Thx

There should be 3 wires.

With sensor disconnected and Key On Engine Off you should have:

12V on the RED wire.
Ground on the PINK/BLACK wire.

Plugged in with Key On Engine Running and back-probing the BROWN/WHITE wire, you should see a nice square wave on a lab scope. Not much you can do to troule-shoot this without a scope. You wont see the signal on a multimeter as the frequency is too high.
