    Default How to replace the optical sensor [VIDEO]

    https://youtu.be/RokBPqLabTU

    Its been a while since ive been on the forum, but i just had to replace the optical sensor in my 99 suburban.
    I searched on youtube but couldn't find a video of the process, so i decided i should make one!

    Hopefully, this will help someone else!

    i was having similar issues to a recently purchased 96 c1500..turns out it was the stupid noise filter that was bad...NOT the optical sensor!!! btw, i watched your video a few days ago..thanks!

    It is possible, but I never recommend doing it. There is no way to calibrate and it has a 1 in a million chance of working. They need to be calibrated on a pump dyno off of the truck. It may cause more problems than it is worth.
