Did you change both sensors? I think there are 2 but not positive for your year. Usually posted as an upper and lower sensor. Search CKP here. You'll get a lot to wade through but your answer should be here.

P041....CaMshaft Position sensor (CMP) signal fault. The single sensor in the drive belt end of the rear cam cover ? Held in by a 10mm bolt, and murder to get to ?

If that's it, you're in the wiring harness tracing business. Might be a dirty connector.....any oil leak in the cam cover gasket goes right to that corner.

The CranKshaft Position sensors (CKP) (2 - A & B) are down on the side of the block next to the oil filter adapter.

OBD-II uses P0340 and P0341 for the CMP codes.

Did you clear the codes, and if so, is the P041 Current or History ?
