    I have no idea what is going on with my Hybrid. The other day the diagnostic threw code 22 VTEC Oil Pressure Switch defective circuit or unplugged / defective oil pressure switch and I just checked it again this morning and now it's code 21 (VTEC Solenoid Valve defective circuit or unplugged / defective solenoid valve)

    I'm going to check the wiring back to the shock tower and ECU and also the connection at the vtec solenoid...

    Just have no idea why it would go from one code to the other. I did remove the vtec oil pressure harness the other day and plugged it back in. Maybe it was not on correctly and that is the problem with the solenoid valve

    Be back in a minute......

    Back ---> Checked the connections and everything looks good. Maybe time to take the car in to a shop :-(
