i am changing the knock sensor on my cl does anybody have any idea where it might be

 

In the back seat.

 

whats a knock sensor?

 

so u wanna change it but don't know where it is...

 

yeah its right above your oil filter. i just had to change mine, its really easy but its hard to get a wrench that fits it so good luck.

 

old thread but what your describing is your oil pressure switch
knock sensor is just to the left of your oil filter

 

oh wow really? how this..."its in the area of your oil filter"

 

that would be worse, as you now know that both sensors are "in the area".

 

being that an Oil pressure switch looks nothing like a Knock Sensor, then yes, its in the area of the oil filter.

 

to someone who hasnt seen both how would they know the difference since the oil switch is covered by a boot and the knock sensor has a huge clip covering it...

just thought i would clear it up since i made the mistake up trying to unclip the knocksensor thinking it was the oil pressure switch back when i was plumbing my oil feed line. fricken broke my knock sensorwhile trying to unclip it... that SOB is so britttle and cracked opened. cost about 200 bucks for a new one too

 

true. but if you bought the sensor to replace it, you can see which is the correct one.

my knock sensor blew out! thats when my engine overheated bad

 

What does the knock sensor do?

 

Senses for knocks

 

didnt you get a CEL? which woulda put it into limp mode? if your car overheated it was for sure not your knock sensor. maybe air in your coolant...

my stupid coolant reservoir didnt work worth a shit... my half rad was like half empty but my engine temp guage never read past half hot either... musta been a good rad... but my turbo seals blew due to not getting any coolant......

 

no, my knock sensor got blown out after the car overheated. the heater core tube failed and let all the coolant out all at once, causing it to overheat really quick. burnt the headgasket
