2003 Pathfinder 3.5L p0011 p0021

[Rustfree]

I have a 2003 Pathfinder with the P0011 and P0021 cam over advanced codes. It only has 140k on it.

I tried a filter and oil change first, no luck. Then did both cam position and solenoids, still not fixed.

Doesn't have any noises at start up like loose timing chain.

Has anyone had to put the actual cam phasers in? Did that fix the P0011 and P0021 codes? Seems odd that both phasers would go out at the same time?

Thanks for any help.

Great question. Replacing parts with no improvement is frustrating as hell.

Have you done the timing relearn procedure? If so, keep in mind, a worn tensioner or slightly loose chain are NOT necessarily going to make any unusual noise, and can only be confirmed by pulling the inspection cover. 140k is about due, so I might do the inspection and then budget for a water pump / chain / tensioner replacement.

Keep us posted - you got a great rig, it's worth maintaining!
