PO332 scanner code???
1999 GMC reg cab 5.3 auto...I have been getting a PO332 knock sensor low input bank two. What does this mean and were do I start looking to fix it. I have hooked up my scanner and erased it twice to make sure it wasn't a false code but it came back . So what do I do now?Any help or advice will be great. Thanks in advance..

pull the intake off, check the holes where the knock sensors are to see if they are full of water, clean out holes, clean corrosion off connectors, clean connector on sensor or replace knock sensors, use a sealer on side of rubber caps covering holes to prevent water from getting in

I believe that there's a TSB that outlines this exact repair...

I happened the next day after washing the engine down. Will the water that got in there evaporate? and I don't have to go thru removing the intake to check the knock sensors? or should I just replace the knock sensors since my truck has 147,000 miles on it. How can I prevent this from happening again? I've heard the intake doesn't seal well in the front is this true?Thanks in advance..
