Okay heres the deal, the wiring harness on my supercharged z6 was fucked, it was cut and saudered in like 20 places, I got a clean harness, rewired the engine, most of the previous codes I was getting are gone, but Im still getting code 21, which I believe is the vtec pressure code. If anyone could give me some help on what to do next let me know, do I need a new solenoid? Thanks

 

the code is for the VTEC spool solenoid valve, do I just need a new solenoid?

 

is the new harness a vtec harness? what model is your car?

I have a 94 civic cx, the harness was from a 95 ex, and was exactly the same as the old one

 

anyone?

 

if the vtec wires werent ran to the shock tower plugs on the car you are going to have to run them yourself. a4 to the solenoid and d6 to the pressure switch

 

there are 3 wires total going to the vtec solenoid, a 1 wire plug and a 2 wire plug

 

yes, the second wire off the pressure switch is just a ground

 

so what should I do to try and fix the problem?
