Probably a repair. There is not a lot you can do the OBDIIA ECU.Quote:

Is throwing code 22 VTEC pressure valve
reason is because OBD1 ECU's and Engines have a VTEC Pressure switch
OBD2A engines like your EK4 don't have it
IIRC there is a so-called bypass method, you'll have to look it up tho as I don't remember how its done
Okay, makes sense, thanks. But from what I can see in the engine bay it looks like it does have a vtec pressure switch? I can take the plug off and there's oil inside.. Same on my obd0 b16a in my ef9..
post a pic of your EK4 vtec solenoid
Nevermind, I was looking at the plug lower down, here's a pic just to be sure anyway Attachment 28044
Found a few tutorials on making the ecu bypass it will give it a go tomorrow
lower one is ECT sensor

vtec pressure switch looks like this

Jumped 2 wires on the ecu plugs to bypass it looking for the vtec pressure switch and everything works now, should have done this years ago, such a difference compared to the p73 ecu! The car finally feels good to drive just like my ef9, vtec engages earlier, way more drive-able now, thanks guys
don't jumper the wires of the VTP as you will get the code again when you hit VTEC, you can jumper VTP to VTS to get rid of the code
I thinks that what I have done, no code when vtec engages, just did exactly what it says here, Attachment 28060
