Knock sensor 2006 SANTE 220 ZR6 motor

[Mlagrone]

my last trip to the water a plumbing fitting came loose on my piggyback ballast tanks and i drained the tanks into the bilge and did not know it until today.
The boat idled fine until i gave it gas out of the slow zone and it fell on its face. after wondering what in the **** was wrong I opened up the engine compartment to see water flying all over the engine from the pulleys being submerged in water. I was able to make it back to the trailer and pulled her out of the water. Drained a lot of water out of the bilge, it got wet... ran fine for a couple hours, like normal. Then the check engine light comes on. I was careful to watch the temp gauge, volt gauge and the oil pressure all was fine until it started beeping and the "see dealer knock sensor" message was flashing. Turning off the batteries for 20 min did not clear the code.
Any advice>? it does not make sense that the sensor goes bad because it got wet... its a boat? need help...

[Mlagrone]

no advise guys?

The check engine light only comes on for low oil pressure or high temperature or faiing oil pressure or temperature SWITCHES (not sensors). It is likely that the switches are shorting out due to being wet.

Same thing with the knock sensor. It is in one of the block drain plug holes, so it was definitely underwater.

One word of advice. Always run with your auto bilge pump on. That way if water piles up like that, you'll see it being pumped out the side of the boat and know there is a problem. These boats all use auto bilge pumps, so they won't run unless they sense water, but they have to be turned on to work.

so do you think the sensor will dry out? or do I need to start crawling on my face to search for a sensor that got wet?

[Mlagrone]

guys, I need help... My mechanic friend told me to disconnect the negative battery cables for 30 min... did that knock sensor beeping is STILL happening "see dealer" there has to be a diagnostic port? I cant find it. its a 2006SANTE ZR6 im convinced I just need to clear the codes.

Wouldn't surprise me if the knock sensor really was bad. Happened to me several times on my 206. Once it got wet, other times, just failed.

[Mlagrone]

where is the knock sensor located on the ZR6? and how would I trouble shoot? frustrating to say the least, beginning of summer and this...

[Mlagrone]

I have been reading on this site, downloaded a PcM manual and found that the knock sensor(s) are located under the intake... :-( so I would like to try to clear the codes with the code mate. Can anyone tell me the model code mate I need? for the 2006 PCM ZR6?

The code mate reader may not work for you. It depends on what your diagnostic plug ports look like. For my 2007, I am presently renting a Rinda Techmate pro scan tool with I believe adapter 94026 from michiganmotorz. I’d suggest giving them a call. If your diagnostic port is a single 10-pin and you have the the right ecm for the reader, then the code mate might work for you. https://www.michiganmotorz.com/codem...fi-code-reader

Did your boat start with that code? I pulled up to the dock after wake surfing and when I pushed the start button no crank and check engine light. My boat has analog gauges so I don’t get messages.Good advice running bilge pump. Good luck correcting your issue!
