mine has thrown this code also, 55000 miles. it has dino oil not synthetic ( bought the car about 3 weeks ago thats what the dealer put in it) so..change to the correct weight syn oil or pull the ex silly noid and check screen?or just stick one in there? also is there a updated chain tensioner that can be eazely used with out tearing the front off the motor? like for the one up on the head for timing chains not the internal one for the balance shafts&h2o pump.
If I remember correctly you have a 2006 NA 2.4, correct? If so, the mineral oil isn't a problem. Don't bother to check anything, just replace the solenoids, and i would do both out of principle. As noted, there aren't any alternatives to the tensioners.
