Vtec Problem - Reward !!!!
Ok. I am going to post this is a coupla forums. Here the problem.
1996 Integra GSR
Can't really notice vtec lately, so decide to investigate this weekend
Put 12V to selenoid. clicks fine.
Getting 12 volts from the Vtec pressure switch, so assume thats ok.
Expect vtec to kick in around 4800 to 5200. Don't really hear or feel a change in that range. So I direct wire the selenoid valve to a switch. Run engine up to 5000
and hit switch. Deifnately hear the pitch change going onto the vtec lobes.
The only thing I found a little strange is I have the 12 volts going to the selenoid
( Previous to the direct wire switch setup) but it does not seem to have enough amps to click on the switch when I get to 5K. Tried this several times with a buddy and we can't hear it click. So here I am 4 days away from a race and I think ok, I just hot wire this sucker. Works great the first time through the 5-6-7-8 K range
On the second run up the engine check light comes on and 6.5K is all she will do.
So, I try this again without the connection going back to the ECM/pressure switch.
Same deal. The code is 22 from the ECM. Well, now I know the vtec has not been working lately which sorta means I have been racing a SSC car in SSB class. So if I can get this solved by this coming weekend I stand a chance of finishing well at Road Atlanta. I am totally stumped. Reward of at least $25 to anyone who knows how to solve this issue, and changing everything doesn't count.

I think you may have a problem with you VTEC Oil pressure sensor. It is a green 2 wire sensor on the passenger side of your block. It doesn't sound like it is sending the correct amount of resistance.

Re: Vtec Problem - Reward !!!! (dskull)
I would check the screen on the vtec solenoid assy., you have to remove the solenoid from the head 3 10mm bolts. That can get clogged up, but very rare.
If it is the oil pressure switch, to save some money, use one off a SOHC vtec motor.
Good luck
