Re: Vtec not working ? (abolish415)
Are you asking because you think your vtec isn't working and you want to know how to determine if it is functioning or not? Or are you asking how to determine why it's not working? Are you throwing any codes?
In either case this is a good thread https://honda-tech.com/zerothread?id=830163

Re: Vtec not working ? (abolish415)
There are a lot of things to check, oil pressure, ecu, wiring, oil pressure switch, vtec control solenoid, but first thing i would check is if there is any slight little dent in the oil pan, it will block oil flow and reduce oil pressure below the required 55psi to engage vtec, and look closely, even a slight dent in the right spot will block the flow enough
