I think I have a bad ecu, and am throwing a code 22 (vtec system malfunction). I think its my ecu. Can I install a VAFC or Fields Vtec controller and bypass the ecu to engage vtec, even though my ecu wont engage it? Someone help!! I have checked the oil level, and I am sure all the wiring is correct. Anyone?

maybe u should cheeck your oil. and add some.

code 22 is vtec solenoid.

check for voltage, but first check your oil.

 

do u have a jdm motor?

 

yes, its a jdm b16, and i have checked the oil level as stated above.

waht year is your car, u might heave to wire it directly from the vtec solinod to the ecu, if u have a b series motor in a 93-95 EG u have wire vtec and knock sensor, if u have a 92 it comes pre-wired, check this website out it was very hepful to me http://tech.hybridgarage.com/
Good luck!!!

 

its in a 91 integra rs.

 

I would definatelty check your soliend before u start blaming the ecu, i had the same problem earlier this year, and it turned out just faulty wiring.
