knock sensor

[seanjuan]

i'd say it's both codes

it's very possible that those two things could get messed up

22 is vtec oil pressure (check your wiring)
23 is KS, again check wiring

the first thing I would do is test the wires for continuity
in other words make sure there are no breaks in the wire

then i'd make sure that the pins are in the right place in the ECU harness and that they are in there good
hopefully there isn't anything wrong with the actually sensors and it is just the wiring. good luck

PM me if you need some help on any of that

is there a special way to get the knock sensor out without breaking it?

reseting the ecu got rid of code 22.

to get the knock sensor out. use a deep well socket. it just unscrews.
