Where would you look first

[Levi's Panther Mica VZ SV]

I'm a new member so please let me know if I do anything wrong


I have a VZ SV6 2005 model Commodore, last week a check powertrain light came on. I managed to get a buddy to plug a scan tool in and the codes that came up are.

P0336. Exhaust Camshaft Position Sensor Range/Performance (Bank 1)

P0391. Exhaust Camshaft Position Sensor Range/Performance (Bank 2)

She's done 249k and I haven't changed the timing chain yet so I'm thinking it is stretched but the other things I thought it could be are faulty sensors or the cam lobes are worn down.
Is there any test I can do to find out which one it is?

I just drove home from work and I remembered that the exhaust sounds a bit drony now and it is a bit sluggish

Thank you for your help

afaik crank angle sensor is a pretty common fault.

looks like exactly what you have here.

Thanks for a speedy reply

I could be wrong though!

Wait for a few more replies.

As you can see through the forums - there are quite a few things that bring up Check Powertrain on the VZ

I did have a look at some of the other posts but I couldn't find one with the same fault codes as mine
