I don't understand why my VTEC isn't working. I'm using the B16 wiring harness, with a PW0 ECU, and I'm even using a Hasport VTEC wiring harness. This swap is in a '91 CRX Si . We couldn't use the Si wiring harness due to different distributor/ignition plugs. Could it be that I have a bum VTEC solenoid? I'm getting codes 6 ( Engine Coolant Temperature) and 22 (VTEC Oil Pressure Switch).
