    Replaced the timing chain tensioners on passenger side to resolve a tick I had. Got the truck back together started it up and it runs good with no tick! Let it idle for a bit then when i pulled it out of my shop i noticed a CEL (P0018 Crankshaft position - camshaft position correlation Bank 2 Sensor A). I double checked that the sensors are plugged in (two on top of valve cover at front of engine). I am afraid that my timing is off but it is running smooth and not trying to do another tear down if I dont have to. I have seen others with this issue on 1st gen tundras after timing belt but none came back to confirm the solution.

    If timing was off a tooth would I notice it driving or at idle?

    Feel like a sensor going bad right after timing service is not probable, but is there a way to test?

    your CEL reminded me of my CEL, but it was P0095, same Crankshaft position sensor, but thats in the belly of the beast, and it wasn't the sensor either..... it was the starter... :oops:

    Yeah ticking stopped when I replaced the tensioners. The main tensioner had failed and secondary didn't look good either.

    Ouch. My suggestion would have been to try resetting the CEL, and try again before tearing down again. Did you try to reset the code? Any clue on how far off time you were?

    A lot of work, but you got it right in the end. :thumbsup:

    Yeah I cleared code and got false excitement when it stayed off for a minute or two.

    I also swapped bank 1 and bank 2 sensors to verify it wasn't a bad sensor or loose plug.

    I am guessing it was only off a tooth since it ran fine and no misses or rough idle.

    Took a lot less time the second go round but sill a lot of work. Just glad there are no CELs this time!
