That SILVER NUT You will see this when you are standing on driver side..underneath intake manifold and uicp
attach to a black part of the engine and has wire connected to it, (which now disconnected pic 1).

Now the STORY.

Im supposed to dyno tune for 109 oct but tuner had to stop due to
multiple knocks from 3200 rpm all the way up top with ZERO timing.

My car is built 2.3 with stock head, ix turbo and 264/272 cams..
Tuner suspected something mechanical problem...after researching i was able to find What
i thought knock sensor...

The Condition i found it.

It was somewhat loose (can turn with my finger with moderate effort)
metal TAB connected was partly broke but halfly connected.

Is this the problem?

 

the broken sensor tab?

 

Why don't you be a bit more specific, add an arrow or circle to narrow down WTF you're talking about.

 

Looks like the knock sensor, but I dont think it is. Any check engine light on?

 

lol....how i wish i can i have to ask my sis to do this...tech. challenge here.
nevertheless, that nut...what the heck is that..help!

 

dude, what nut are you talking about?!?!

 

 

^ YES Sir...you got it thats what im talking about...TAB is supposed to be attached to SENSOR

 

Is the check engine light on??

 

im guessing you need to buy a new sensor. i would just go to the dealer and look at a parts diagram

 

knock sensor

 

no..

 

That's not the knock sensor wire from the looks of it. There is a 2 pin connector for that sensor. That looks like a VDO oil pressure sender or something.

 

that is the knock sensor...mine did the samething...all i did was cut the tab an replaced it with a speaker wire terminal an took off the screw from the top of the sensor and screwed it back on with the terminal attached to it.

 

This is what the Evo knock sensor looks like.
