SO i bought my 99 MAX SE last year and the CEL did not trip, i ran the codes at auto zone anyway and the knock sensor came up. I looked at how to change it out, and it doesnt look like my car even has it!!!! is it possible someone knew it was bad and just chopped off the sensor harness and all???? it is a cali spec car.... is the knock sensor anywhere different than the rest of the 4th gens??? I think i see the two ground wires that are located in front of the manifold, but i dont see the knock sensor anywhere!!!!!!!!

PLEASE HELP ME, im missing my HP and timing!!!!

 

You have a Cali Spec car. The KS is hidden behind the Swish valve actuator. Remove the vacuum actuator and the rod and you'll see your KS. It's a real pain in the a$$ to change them on Cali Spec cars. Good luck.

 

Thanks for the quick reply... any idea where these things are?? i am car iliterate, but looked in the haynes manual and they dont even mention a vacuum actuator.... is this a job for my good ol' neighborhood stealership????
