I'm having the same issue with my 06 Tahoe Z71. 70-75 miles an hour I practically have to floor it to make it up hills on the interstate.
The check engine light is currently not on: Will there still be codes present even though the check engine is not illuminated?

It has a monitor code and a fault code but I do not know if the monitor will be on if it has not detected a fault.
I swapped mine out and the rear was completely rusted, When I replaced mine I took RTV and sealed the rubber grommet of the wire harness and where the wire goes into the grommet to keep moisture out.
And did it fix your issue?
I'm curious to know as well.
Sorry, been away from home. Yes! It solved my issues, The tahoe runs smooth and everything is back to how it was! Thanks for the help!!

Might have to look into this now. My truck is doing the same thing between 50 to 55 only when it's floored though. Normal even moderate acceleration doesn't get it to hang up. But when it's floored it does it around 4700rpms.

Just found this. Went through a big puddle last week. I am pretty sire this is the culprit now. http://dirtyshirt.info/auto_knock_sensor_replacement.html

well.....Got the p0332 code again. It seems to only trip if I am on the freeway. P0332 says low voltage so is this a knock in the motor or just a bad sensor? I noticed that the rear bank was super rusted so would that prevent a good ground and cause this code to be thrown?
