Camshaft problems?
 

I had my 2002 Boxster 2.7 base die while idling at a red light. After several tries, it started and ran rough. I limped it home. Read codes of 300,301,302,303,343. Cleared them and restarted and still shows 343 camshaft position sensor bank 1 exceeds value. Still runs rough. Durametric has cam deviation for both banks as 0. Actual value for camshaft bank 1 is 0. Actual value for bank 2 is -12.92. Can anyone tell me what these numbers mean? Could this just be a bad cam position sensor or is there something else I can check?

It is most likely all caused by the one sensor acting up. You need to go hands on and determine if it needs to be replaced or is just disconnected (wiring harness issue).

I put a new AOS on it about 3-400 miles ago. Is it possible I pulled something loose? Isn’t the cam sensor pretty much under the AOS?

You are way out of specs, so an alert is triggered.
Probably variocam wear

Some of us have changed the variocam pads resulting in the camshaft timing numbers not changing more than a degree or 2, and in some cases, not at all.

Next step is to examine the oil and filter for metal.

I finally had time to dig into this. I took off the aos to get a look at the wiring. Everything looked ok and the voltages checked out ok. I went ahead and replaced the cam position sensor just to be safe. I put everything back and it seems to run a little better but still rough at idle. CEL comes on after a few minutes with the same P0343. I checked the cam timing for bank 1 and it looks like it's maybe a tooth off. Suggestions on what I should do from here?http://986forum.com/forums/uploads02...1534107234.jpg
