Knock sensor error
2007 Tundra Crewmax 5.7l 4x2
Just wanted to throw this out there for the knock sensor error code P0333. In my situation I was getting a knock sensor error code, so I pulled the intake replaced harness because of rodent nesting. Minor chew makes on harness. Code went away or so I thought. It would randomly return. Took it to dealership they wanted $700 to replace bad knock sensor. ROFLMAO!
My issue was that after driving randomly around the money light would go out. So I thought maybe faulty sensor but I had checked them all while changing harness.
Well I located some on Ebay (Toyota OEM numbered part) for a great price and figured that next time money light came on, I would swap them out, all four. If one is going I'd rather do all than just the one.
Anyway, it wasn't the knock sensor at all. Turns out that I had a low oil level that would trip the knock sensor, more frequently for me because one of my driveway was pitched. If I backed into the driveway with front of truck pitched downward with low oil level it would trip the knock sensor.
When I parked with the front of truck pitched upward, I would not get the error code.
So, if you are getting the Knock sensor error code. 1st check your oil level. I was and am currently tripping Bank 2, Sensor 2, when parked front of truck pitched downward.
I have checked the oil religiously since and have effectively saved myself $700 dealership fees for one knock sensor.
Hope this helps someone.
