93 si 4ws swapped h22a...wired vtec onto p28 on a4 and d6....everything is good however i think d6 on the vtec senor or the ecu pin doesn't have any power. I tried looking it up and everything. even tried ohm meter...nothing! I'm very frustrated to this point. No vtec makes me sad Please help !!! thanks guys!

 

is your speedometer working?
Do you have oil?
are you using some sort of hondata with that p28?.............

 

yes my speedometer works, i just recently changed my oil 10w 30 mobil 1, and everything.....i suspected oil level first b/c I changed my vtec soloniod gasket cuz it was leaking, then I silicone it.

 

Are you getting a CEL?

 

Maybe the silicone you put in, is blocking the vtec solenoid filter, and is not getting oil.

 

put it this way....it works and sometimes it doesn't work and yes i am getting a 22...vtec pressure valve right (aka: op switch)...i don't it's the the silicone and i didn't put a lot...just a little bit...the spool solnoid was replace and cleaned w/ carb. cleaner....nothing dude....I think it's just the wires not connecting right...HELP

Well test the pressure switch for continuity, triple fkn check your wiring, DONT USE GHETTO CRIMPS FOR ENGINE HARNESS WIRING. Please solder and heatshrink.

 

i am testing it w/ the ohm reader.......i use to have a h23 so i have to wire my own vtec rite...well i tried finding the right size pin for d6 the small one and it fits...however...why is it still tell me it has a cell 22....i might need to change the vtec senor....but i dont' want to waste money if it's not that....damn!! been like 1 month already!

 

how can you check if your having enough oil shooting to the head? b/c i think i don't have enough pressure building up to balance out my vtec....? please help

 

You would connect an oil pressure gauge to the hole in which number 21 blocks(lower left corner).
Just take out the plug, and screw in the oil pressure gauge. You can get a cheap mechanical one from auto zone/ napa/ etc. Once the gauge is connected, turn on the car and increase revs until you see pressure. It should have little to no pressure until about 5.5k if I remember right. Sorry I don't have my helms in front of me to give the exact procedure.

i forget if theres any seals in the spool valve that the carb cleaner you used could damage...that would explain it working sporradically..first check the spool valve for any crap like the silicone getting in there...then make sure your wires and switch are good, and lastly check your pins on the computer

 

hows your oil pan? i was having trouble with vtec in my h22 accord because my pan was dented, i pulled it off banged it back out with a hammer and its all good now.

 

not quite sure how's the oil pan...i know short of these conditions however it wasn't like it did this b4....i'm missling at least 2 screws in the oil pan...but nothing biggy....i just think after my tb chewed up 2 months ago....then everything started messing up....i think my valves are bent but not sure b/c it runs fine...just vtec...

 

well...yea ...i kind of used a lot of carb cleaner to clean the whole vtec solonoid when i took it out for inspection....i did put silicone only when i put the vtec back...just a little...i doubt it's that might i'm not here to say your wrong...i will check it 2morrow...thanks dude.... ....anybody know where a good motorshop to build a head....i need new valves.

 

bump!!

hey man, i got a h22a swap in my 92 si, and my vtec didnt work for a while, i bought i new pressure switch for 50 bucks and that didnt do it, i also had a code 22, pressure switch, i checked continuity to the switch, and all the wiring, and it ended up being the connection to the ecu, i used a paper clip to get contact and my light went off!!1 VTEC haha but got a dui and cant drive for another month so the lude is resting, u want to get a shop or dealer manual for a honda and they go through step by step how to trouble shoot the vtec. if ur still having problems, and u have checked all connections, oil pressure and pan, ecu connections and warmed ur car up i would check out ur ecu or try a new pressure switch, if u cant borrow one from someone ill send u my e4xtra one if u want to see if that is ur problem. ull figure it out dont worry, u will feel so good when its fixed tho i was frustrated as hell

P28? you might want to try a p72 because the p28 doesn't allow the secondary runners in the intake manifold to open.

Or it could be your out of oil or your oil pressure switch is bad.

 

yea...that's my next thing.....it soemtimes goes off when i start the car....and then after a few vtecs...it'll show up....again....then sometimes it'll stay like that the next time i start the car...weired....?

 

also....the only thing is that my temp. is way off....it's always cold....i change t-stat, and ect from honda.....nothing.....waste of money. i want to fix but don't know how.....maybe it's cuz of that.

i would put money on that this is your problem.. the ecu needs to know the car is warmed up

 

i know it needs to be warmed up....BUT i changed everything already: t-stat and ect sensor.....still cold....waste of money...wat else could be the result of this problem?

 

wat's sad....last night is that i was going to Curry House w/ a few friends: one w/ a eg hatch single head and the other is 5th gen prelude...they both spacked me cuz of that PROBLEM.....deng....lost by a single head!!! NOOO
