I've been getting this code for a while now:

P0333,Knock Sensor 2 Circuit High Input (Bank 2)

Can someone tell me how hard it is to replace the Knock Sensor (Bank 2) and where it exactly is?

The knock sensors are on the engine block under the intake manifold. They are circled in red on the attachment.

Drauden, I'm getting this code as well for bank 1 and 2. Did you manage to resolve it?

Drauden, thought you might be interested in this. I used a borescope to inspect the knock sensors on the truck but came across a bunch of debris. Got the vacuum out and sucked out about a cubic foot of leaves and shredded newspaper - something was holidaying between my cylinder banks! I could see the wires going to the knock sensors and they are both a little chewed up. So now I'm thinking about pulling the intake manifold and try to re-wire the leads. Would rather not buy 2 new sensors @$100 ea!

Any thoughts from anyone whether this is worth the trouble? I'm worried that if the sensors are out it will not prevent detonation issues, should any arise. I've removed my 2* advance as an added precaution. (don't actually know if it does any good or not)

Any advice is appreciated!

Hello Drauden! Thought I'd offer my .02 pennies on your knock sensor wires. I don't see you having any problems with repairing them just as long as you have enough wire length to repair. Using quality solder and heat shrink to cover your repair should do the trick. I have had to repair such wiring damage done by field mice to numerous sensor wiring on electronic control devices and have met with success. OH and SCR38, Is that your motor with looks to be like a new top end? Maybe more! Hahaha!

I cleaned out a ton of mouse housing debris in there about a year ago, but never inspected the wires. I suspect that I am having the same issue as you "drewcs" I'll have to take a closer look at it now.

thanks,

No, that isn't my engine. Mine has never been into.
