So I installed a JDM h22 in my 92 accord, and it runs great... except, no vtec, and it revlimits at 6500. I checked codes and i get a code for vtec pressure switch, code 22. So i rechecked all my wiring, and checked the switch, and got a good test there. not sure what could be wrong, and i was wondering if anyone had any thoughts on what could be wrong.

i have 3 CELs right now, 6, 10, and 22
that's IAT, ECT and Vtec pressure switch

 

make sure you are grounded with the vtec. good connections etc.
