Hello everyone I recently purchased a 1994 hatch back dx that had a z6 swap in it and it was missing the engine harness for a z6 and computer after getting a z6 harness and p28 computer I wired up vtec and am almost certain the wiring is correct I'm still getting a code 22 I have swapped vtec solonoids and pressure switches and have tried a different p28 computer and am still getting a 22 there is absolutely no vtec it won't engage at all I have made sure oil level is correct wanted to see if anyone else had a take on it this cars driving me nuts

Double check your wiring... and the main engine harness ground at the thermostat housing.

Disconnect the battery and check continuity from pin D6 on the ECU to the pressure switch connector. You can also bypass the PS by installing a jumper from A4 to D6 on the ECU side of the harness. If you do this, make sure D6 is not coneccted to anything else.

If I install that jumper wire it will only turn the cel light off tho correct cause it's jumping the solinoud to the ps On the ecu and I'm gonna check wiring first the only thing else I know to try is to run a individual wire from the signal wire of the ps and pin to computer like I did with the vtec solinoid my problem is I have a vtec engine harness but the shock tower harness is for a non vtec

Then run the appropriate wires! Run directly to the ECU and loom them with the others. Problem solved!

Gonna try it today will update after work thanks for the input

That's the spirit!!

So I ran a individual wire from the pressure switch connector and pinned it to the ecu and no more cel I'm guessing the wire I used in the factory harness had a open in it thanks for all the input now I won't have to set it on fire lol

Woohoo! When in doubt, just hardwire the **** out of it!! The one thing I don't like about Honda is their silly wiring. Everything grounded to chassis and when those get jacked, things start going all caddywhompus, and GOOOOOOOOD LUCK trying to find the bad spots...
