PO342, Camshaft Positioning Sensor ? My car recently died while driving it. The codes that were stored were the 2 for my rear O2s and a PO342 - Camshaft Positioning sensor low input. The car turns over, but wont start. I can hear the fuel pump cycle. I am kind of thinking that I broke the timing chain. Would this code be a symptom of that ?? Where is the camshaft positioning sensor ? Tomorrow I will pull a valve cover and turn the car over. If the valves dont move then that is my problem.
Thanks in advance for the help.

Re: PO342, Camshaft Positioning Sensor ? Yep, had the same thing on friday - timing chain.
If you remove the oil fill cap, you can likely see a rocker enough to realize it is not moving.
You may also notice that it cranks more quickly due to lack of compression in some or all cylinders.

Re: PO342, Camshaft Positioning Sensor ? So far it doesnt appear that I bent any valves. I checked the driver side and the they seem to hold air. When I release the hose all the pressure comes out the fitting in the spark plug hole. I will check the passenger side tomorrow.

Re: PO342, Camshaft Positioning Sensor ? I had that sensor fail, it's been my only problem so far with the car, Your symptom is exactly what I had and the same code. Pep Boys couldn't figure it out (no code), my friend with a diagnostic couldn't figure it out (no code), the dealer found it in 10 minutes. The tech told me that that code sometimes won't show itself, he changed it out, if I remember correctly it was $43.00 and it ran perfect again. I also had 6 other codes which were coils and wires, but it was all caused by the "Crankshaft Position Censor". Nothing was damaged. However, he said major damage could happen if I kept trying to drive it like that. Mine would both suddenly die or drive OK for a little while (maybe 10 minutes) and then die. Sometimes it wouldn't start for 6-8 tries in a row.
To the dealer.

Re: PO342, Camshaft Positioning Sensor ? Yeah we do. I just pulled everything out of the car today. Heads, radiator, Cam etc.. The timing chain was definitely busted and I bent at least 2 valves on each side. So the heads are going back to MMS to get setup by them. So is the cam, because I am getting the big daddy 229v2.1. It only took my friend Lino and I 3 .5 hours to tear the car down.
