Hi guys!

I was out on a high speed test when the car just died. Just lika you run out of gas. I have a spark and fuel pressure in the rails. But it wont start! The only code on my DIC is "P0343" Camshaft Position (CMP) Sensor Circuit High Voltage . Whats wrong? I cant see any damage on the cabels or anything. Is the Cam sensor broken?

You have to pull the intake manifold to change it and/or look at it to check it...chances are if you have that code then its the sensor thats faulty. Also check the wiring to the sensor. If the PCM detects that the cam signal is stuck high, when the signal should be low for 1.5 seconds, it will throw that code.

I have the sensor in my hand right now, is there a way to see if its broken?

i have the same problem... i put in a new cam and that's the only code that has been showing up since. I replaced the sensor, but it still doesnt work, checkd all the wiring and everything looks ok, but still have the code.. so i know what your going thru. my car will start, though it runs like ****!

We un-plugged the cam position sensor on a guys truck as a joke. would turn over but no starting, lol. Replace it and go from there.

The car can run by just the 24X crank sensor signal, but like you said, it will run bad. It needs both to run correctly.

It wasnt the sensor it was the timing change. I have to look how my valves looks like.. I hate my car right now.
