    So, after 12 years and 160,000 miles, I decided to replace my timing belt. I watched all the YouTube videos and bought a kit containing the Aisin water pump, gasket, idler pulley, tensioner pulley, and the O rings. I also bought a serpentine belt with Idler pulley and tensioner pulley. The whole thing went pretty well with the exception of a rounded off bolt on the skid plate. Obviously done by someone at an oil change place over the past 12 years.
    After I completed the job, I started the truck and took it for a test drive. The engine light came on with P0016 and P0018 code indicating that crankshaft position, camshaft position correlation bank sensors. This would indicate the belt is not positioned correctly. I installed with all the marks in place and rotated the camshaft twice to double check. everything seemed fine.
    I cleared the codes and test drove it again. 5 miles into the drive, the light came back on with the same codes. The truck runs fine. I cannot feel any difference. I pulled a small trailer 150 miles and still cannot tell any difference in how the truck is performing.
    The question is... Should I take it back apart and look at the marks again? I'm like everyone else with plenty to do, but I plan on keeping the truck for many more years and don't want to damage it. Plus, I know how to do it now and it really wasn't that bad. Thanks for any input.

    If it were my truck, I'm OCD so I'd take it back apart and use the index marks on the camshaft and crankshaft from the factory verifying top dead center. If you made your own marks and transferred those marks to the new belt, there's a good chance you are off by a tooth on the new belt. Ask me how I have learned from this mistake in the past. o_O Welcome from CO by the way!

    After you finished the job, did you spin around by hand a few times and verify the timing marks line up the way they are suppose to? If not, I would recheck. Those codes are most likely caused by timing off. This is a common issue on certain Honda years when the timing chain stretches just a little bit because they dont change there oil, and extreme wear and tear. So a chain at that, and I changed one to clear those codes, new cam sensors didn't work, but a new chain did. So good chance you are one tooth off, it wont hurt nothing right off, but fix it soon. It will still run ok btw.
