2002 Q45 CPS issues

[Geothermal]

A few days ago I had my 02 Q45 stall out in the highway. The code was P0340, Cam Position Sensor, Bank 1 Malfunction. So I replaced it and it ran for a few minutes, then stalled throwing the code again. I replaced the sensor a second time, thinking that it was a defective part. Once again, it ran a few minutes, and died again. At this point, I was at a Pep Boys, so I replaced the battery, (it needed replacing as it wouldn't crank on a cold day) and once again, it started up and ran for a few minutes before dying. Each time, after dying, it refuses to start, although it will crank. Any ideas as to what the problem might be? I have considered the wiring, and will be checking the voltage and resistance at the connector, see if there's a break anywhere, but hopefully there won't be since that wiring harness is horrific.

to NICO!

If you don't have the FSM (factory service manual) for your car, head on over to http://www.infinitiservicemanual.com and download yours as a .pdf

There's a whole section on the CPS and possible reasons for your code starting on page EC-340

Some things to check are as simple as loosening and re-torqueing some engine ground connections.

Good luck!
