I have replaced vtec solenoid the whole unit but it's still giving me engine light and going into limp mode. What else can it be.
I just noticed you posted the year, there are two oil switches on VCM engines 2009 on up, so you'd only have one on a 2008. Did you install the new one? Try changing the oil and oil filter and cleaning the VTEC valve screen.One sensor came with the vtec solenoid is there two of them. If so where might I find it.?
