just got done with another h22 swap in my prelude
obd1 h22a blah blah
Code 10 and 21
i rewired vtec completly and its sitll throwing the vtec code :/
i have no idea what is wrong and why it is throiwng the code still
i even swapped out the vtec solenoid with a prefectly good one
is it because of the IAT code?

 

maybe its not wired correctly

 

no IAT will not cause other code.

The IAT is pretty delicate. Did you replace / damage it when you did the swap ?

 

its wired fine i had an h22 in it before i even rewired it
ima try to find a one wire IAT sensor i got a buncha 2 wire ones

 

anyone else know what could be the problem? i even swapped out ECUs
im totally stumped!

dude check your wiring and grounds...the **** sucks...are you sure you have it wired to the right pins at the ecu...

 

yep it had an h22 in it already i figured i crossed the wires or something so i redid it all
and heres another thing
we swapped the wiring from the solenoid to the pressure switch
so that should throw both pressure switch and solenoid code right? no it still threw just the solenoid code

 

I had it wired backwards when I finished the swap and it didn't throw a code until I tried to hit vtec, and then it was only the code for the solenoid, so it may not give you both codes. Just a heads up.

 

still cant figure it out!
