my check engine light came on today so i got out and checked it out and it was code 52 ( knock sensor ) so i look under the intake manifold and i can see the sensor right by cylinder number 2 but when i looked for the one by cylinder 4 it was missing i looked for a wire laying around with nothing on it but couldnt find anything and i checked the wire harness and couldnt see anything so does anyone know what the wire from the ecu to the sensor is my guess it the previous owner cut it out or something.

It's possible it was cut. Coax wire works really well for the knock sensor wiring. Just make sure the shielding doesn't come in contact with the signal wire, that way noise from the ground wire doesn't throw the knock sensor code and cut timing. Good luck.

there are 2 in the front and 1 right on the side of cylinder 4-5 i have the back 2 pluged in and it will idle fine but when i put the car into first and drive then it comes on so my guess is one is working since i dont get the code right away but the second one isnt ( im not 100% sure)
