sup guys,

im looking for the colour of the vtec pressure switch wire. This applies to fellow f22's and h22's.

Thanks,

Allan

 

im thinking back to the swap days, the switch has a green wire for sure, and i think grey as well. But green for sure on 1 of them

 

did you keep ur stock f series harness or did you go with the h22 harness?

 

i used my F23 harness and rewired it to the h22 Vtec switch

 

i was just lookin at the accord helms manual and it says that the wire is blue/black unless im a complete idiot.

The reason for all of this is:

since this swap went down i've been getting "code 22:" which is the vtec pressure valve which has to do with the vtec pressure switch. What i just found out from searching honda-tech is that JDM motors dont come with vtec pressure switches..my motor is a JDM H23A so it obviously doesn't come with a pressure switch, so back when this started happening I swapped on a h22 pressure switch that i thought would fix the problem but of course it did not. So my car has been in limp mode since i swapped the motor and i have had no idea why cuz we've checked everything and i mean everything.

So anyways, i was fucking around on h-t yesterday and found out that since "JDM" motors dont come with pressure switches the way to get rid of the CEL and MAD LIMP MODE is to find the pressure switch wire in the harness and ground it on the chassis then bye bye code 22 and limp mode. So that's what im hoping will fix the problem now i just need to find out the colour of the pressure switch wire.

Also, i would just find it in the engine harness where the pressure switch plug is suppose to be but the shop that did the wiring got rid of it somehow cuz i can't find it.

I don't know if all that made sense but i just put it all out there cuz im tired of not driving my car and not enjoying the time/effort i put into it

wait wait wait... i have a JDM h22.. i saw him wiring that shit..

 

did your motor come with the switch?

 

i can't help u, especially if u're looking at the helms manual cuz that's all i have to help, but just wanted to say hi allan.

 

ok so i went down stairs to look again..

theres 2 parts the metal cylinder shaped thing that has 1 green wire coming out of it... and theres a green plug with a brown and green wire coming out of it.. i took a pic with my phone i can post at work tomorrow..

 

and JDM motors have pressure switches.. only diff between JDM H22 and regular is internal / external dizzy, and no crank angle sensor..


BUT u do have an H23a.. is it OBDI or II?

 

maybe this helps



your car doesnt have the green plug behind the dizzy?

 

i do have that but it didn't come with the motor so i got one off a spare h22 i had lying around. We wired it straight to the ecu and i still get code 22

& my motor is obd2 but i converted to obd1

 

spare h22 i had lying around luv it, u sound like me

 

ya i only wish i could enjoy the vtec..

 

For the OBD1 ecu you can bridge pin A4 to D6 to get rid of this CEL.

I converted to OBD1 and had CEL 22 as well. I disabled the vtec pressure switch it in the ROM using eCtune but bridging those two will do the same thing.

 

yeah i just crossed them together and the light is gone but now i have code 21: VTEC spool valve

 

any updates on this? did u figure it out? maybe you should go back and pull out the H22 component u added and ground the wire.

 

replied to your pm

 

did you figure out what color the wire was? I was cleaning my engine bay and I found out that my VTEC pressure switch on my f23 wasn't plugged in and that the connector is nowhere to be found... I was thinking that maybe the 97's dont have that connector and maybe it's a 98-99 thing only but I don't know,... I have yet to find a wiring diagram that has the pressure switch wire it in... I'm lost

 

i never used that wire.
the cl harness doesnt come with it. you need it for sure man. you need to wire it. if you get me the exact name of the switch then i can tell you what color the wire should be and the pinout for it. im gonna need this too.

 

I just checked honda estore and they show the 2.2 CL having the vtec pressure switch which is what I assumed since a vtec car needs to have that connector in order for vtec to engage... I just don't know why the connector is nowhere to be found on my car. I have the vtec pressure switch on my f23a1 engine and I saw a diagram showing that the 2.2 CL ecu has the pin out for the vtec pressure switch... this is really confusing me...
