Ok, so your ECU monitors oil pressure and engages vtec, then will cut it out if the pressure gets too low from low oil levels, right? My question is, does a VAFC over ride the ECU and engage vtec even if the oil level is too low? I am wondering because I checked my oil and it seemed really low, but vtec is still fully functioning, and the VAFC says it is engaging. Maybe I was on a slight grade and the oil was laying back in the pan, but seemed too low even for that.
