Knock Sensor

[gatorgates]

First time out this season (2002 Ski 206) and the knock sensor warning is blinking. The engine (330 Excalibur) is running fine - no limp mode. I swapped out the knock sensor with a brand new one and the warning is still going off. I cleaned and wd40'd the connections. Still going off. Anyone have any ideas or do I just stick a piece of electrical tape over the warning screen like my wife does on the check engine light on her car?

My buddy has this issue on his 330 excalibur. IIR, he looked into it and the dealer has to clear the code....maybe someone can confirm. His boat runs fine as well.

My 08 330 Excalibur has two knock sensors one on each side of the block attached to the block drains.

I think silent Steven is right. If knock sensor is triggered, you can temporarily disable the warning at the Gage but it comes back. I think only way to get rid of is clear the code through a Codemate on the engine computer.

Might look into getting the Codemate reader for something like that. Cheaper and easier than a trip to dealer. I bought one for about $50 several years ago and keep it in the boat

2nd this post...replaced my knock sensor but seemed to keep happening after long surf sessions, likely due to water in the bilge (need to pump frequently, caulked the rub rail, taped off the vents, still coming in from somewhere). Bought the codemate (based on a recommendation from this site) to clear and works every time, and takes less than 5 minutes. I was told that it is very unusual for there to actually be an engine knock in the PCM330.

The manual says that I can clear this by simply holding the up and down buttons at the same time for a few seconds. However, that did not work. So, where do I get one of these Codemate thingies?

Yeah, the up and down button only turns off the alarm for a short time. Here's a link for the Codemate.

I am a bit late to this thread but on my 2004 Super Air - the knock sensor went off because I had to torque it specifically to 16 foot pounds. Once I did that then the warning went away.
