so i had code 21 than i realized the cx main harness wasnt wired for vtec so i put pins in te plugs and wired it up, than 21 went away. went up the road and fine for half mile now boom got cel 22 2 long 2 short now what... tested continuety of what i just put in and its good is it possilbe i have them mixed up? and after it throws the code it ideas low and lights dim

 

CEL 22 is vtec pressure valve. Check your oil. If that's good check your wiring.

 

yes both are good, i understand by jumping i think a4 and d6 you can bypass it. can anyone explain the benefit of this, its a p28 and d16z6, will it trick the computer into thinking that at idk 5000 rpm its ok to engage vtec?

 

recheck your pin job... ive never seen a vtec pressure swith go bad....

 

ditto, can you show up where you pinned it? should be like this

 

i think its just a loose wire because i had to pin both pressure switch and soleniod... used to have code for seloniod and now dont soo
