Hey i was wondering if you can interchange vtec pressure switch's across the board like will a B series one work on a H series, or F series work on a H series, D series on a H series. You get the idea I'm getting at. I have a 1997 H22A4 motor and I am throwing a code 22. I cleaned the VTEC solenoid screen and still throws code so im just gonna replace the switch. Does it matter if I get a OBD-1 switch off a H22A1 or do I have to use a OBD-2 H22A4 switch?? Any positive input would be great.
