My 350z is misbehaving (sounds like an engine misfire and shows "camshaft timing bank" iOBD err)

Hello,

 

I have not driven my import 350z (2003) for a couple of months.

When I started engine this morning

 

1) started as usual then it dies after a few seconds

 

2) second time - it sounded like a flooded engine but finally started...

 

2) engine still sounded a little rough like a misfire or something, it's rev'd but you can see loss of power - So I called AA to check

 

3) car got checked by AA man to the following outcome:

 

- cables to camshaft timing sensors don' t seem to be snapped

- no rattling or mechanical sounds

- all the other the symptoms above confirmed

- while connected to iOBD following fault codes show:

P0011 - Camshaft timing bank 1 too early on system fault

P0021 - Camshaft timing bank 2 too early on system fault

- these are popping up also after resetting codes and engine restart (with the same misfire-like symptoms, etc.)

 

Anyone with similar experience? Please help.

 

Thank you in advance!

 

Martin

Based purely on codes, it COULD be camshaft sensors.

 

Camshaft Position Sensor Part Number (for Bank 2 / near radiator) Left

23731-AL61A

Camshaft Position Sensor Part Number (for Bank 1 / near firewall) Right

23731-6J90B

 

Obivously cheaper ones are aftermarket.

I take it that when you parked it up a few months ago it was all good. What I would do to start off with, is disconnect the battery for a while. Put some fresh fuel in it. Then run it for a while and see what happens. You never know might just clear it up. Good luck.
