VAFC made me throw CEL?
 

I was ------- around with the Vtec engagement on my VAFC, i took it to like 4000 or maybe a little higher just to see what it'd do and I threw a "pressure switch" CEL. what does that CEL mean? and what could have caused it?

Re:VAFC made me throw CEL?
 

my only guess is that the oil pressure is too low at that rpm for vtec?

Re:VAFC made me throw CEL?
 

or maybe you just fried the solenoid. it does happen. just my 2 cents

Re:VAFC made me throw CEL?
 

check your oil pressure/level i had the same some times ago 8)

Re:VAFC made me throw CEL?
 

yeah, it engages fine at 5000rpm, but too low and i guess there's not enough pressure

Re:VAFC made me throw CEL?
 

exactly, there isnt enough oil pressure when you do it low, because the AFC will still engage it no matter what the ecu says. so if you are ingaugin it to early, it takes oil pressure away from what little you already have.


BTW whats engine do you have?
