Thread revival!
I too am having this problem, I'm getting p1381 and P1386. ( bank 1 & bank 2)
I have removed the cam cover and inspected the timing chain, all of the guides are fine, and the chain looks fine.
I used a screwdriver and got one more click out of the tensioner but that hasn't seemed to help.
has anyone else had these symptoms?
I'm thinking I might remove the cam cover garnish and check the resistance on the sensor next, any other suggestions?
