Re: P0333 Knock sensor high input code diagnosis and repair

I got all the parts in today, put it all back together and everything works again! No codes, more power and overdrive is working!

Re: P0333 Knock sensor high input code diagnosis and repair

I just did this. It was hard. I got the front and rear pipe housings off but pulling the big pipe out of the rear housing was crazy hard. I slid an old chainsaw bar between the pipes and levered against the front welded bracket that connects the big and little pipes and it popped out. I had to space the rear housing away from the head a little because that lower pipe was rubbing on the flange of the housing and I didn't want to pop a hole in it. Once the pipes were free of the housings I got tired of trying to play surgery with the wire connectors so I cut the connector pipe brackets and it allowed easy access to the sensors. It seems the big pipe kind of supports the little pipe so I just wrapped a hose clamp around the pipes and it seems good.
Here's a pic of the saw bar puller and a pic with the cuts and large pipe removed.
