ok so I got my V-AFC hooked up but there is one big problem. I can bring first and second to redline, but the in third when I go to bring it to redline as soon as the vtec kicks in ( i have it set at 5600) the CEL comes on and then my rev limiter is 6500??? WTF??? It throws a code 22 which is vtec pressure switch failuer. I changed the switch and it's still does it. My car is obd1 so if that makes a diference let me know. also what the hell is the vtm sensor and does my car have one? it's a 95 gs-r. COuld it be a bad controller or did I just fuck up the wiring? why does it happen in third? any info would be such a help. also if this has been covered before I'm sorry I did try to use the search function.

Show me youre settings...what are your fuel correction %, and VTEC Unmatch Fuel Correction.

Did you solder/splice the VTM (VTEC pressure switch) to ECM, that could be the problem, go over your wiring and make sure everything matches up.

Did you get your V_AFC tuned by a professional or did you try to do it yourself?

-CODE 22: VTEC Oil Pressure Switch defective circuit or unplugged / defective oil pressure switch

-CODE 22: Front valve timing oil pressure switch (Integra)

I suggest you run a valve/pressure switch check. Basically checking your vtec solenoid and sensors with an ohmmeter and voltimeter.

Here goes:
-disconnect the round electrical connector from the pressure switch, then connect the ohmmeter between the terminals of the switch. You should have continuity because its a new switch...but if not its faulty, replace it.

-If thats A-OK than the next thing to check for are any breaks or misconnections...you'll see a blue/black wire in the terminal, connect the voltimeter to a ground and to the blue/black terminal. There should be approx. 12 volts with the key in the ON position.
If its around 12 volts its okay, if not there could be a bad ground or break in the wires, check the ecu.

This should solve your problem...worst case scenario unhook you V-AFC and see if the problem still exists.If it doesnt, your VAFC could be faulty, installed improperly, or tuned incorrectly.

Whenever problems in the VTEC system are suspected, you should check the filter and O-ring located between the solenoid valve and the cylinder head. Hope that helps.
