While getting the engine to fit I tore on of the sensors and ripped a few wires out of the plugs. I wanted to know what this is? I need a part number if anyone has it so I can order a new one.

 

I pulled it from the back of the engine block right in the middle directly under the intake manifold

 

Looks like the oil pressure sensor.

 

do you mean the oil pressure sending unit? thats all i was able to find in part descriptions. but thats i believe closer to the transmission side and not directly underneath the intake manifold.

this sensor actually had the cable attached to it which in the center of the block. its just detached cause i had to cut the wire in order to get it off the block

 

That's a knock sensor.

 

damn those things are expensive. does anyone have any clue where i can get one for a decent price?

 

does anyone know if MD198158 would also work for the car? I found it for like $70 so figured i'd give it a shot...

MN137468 is the one thats meant for the car. the PN that i put up there is for the 2002-2004 2.0 lancer i believe?

 

nvm. just ended up going to the dealer for the oem knock sensor. w/ tax it landed me just a tad under $200. expensive as hell but i needed it by tomorrow cause hopefully the car will be finished by then ::crosses fingers::
