I broke a sensor while removing the head today. It screws into the block above the oil cooler. It has a red wire with a blue stripe going to it. Could anyone tell me what sensor this is. I can't find it referenced in the helms manual.

 

thats the knock sensor.

 

sounds like knock sensor. the black sensor above the water pipe?

 

Wow, quick reply. Yeah thats the one. Now the question is, do I need it? I am probably going to get a chipped p28, so I don't think I'll need it right?

 

you won't need it with a chipped p28.

 

p28 does not read for knock sensor so you should be fine.
