I have a b16a2 with a b16 obd1 computer engine harness is connected proper.what can be the problem for vtec not kicking on?
have you witnessed vtec ever working properly on your current setup to be so sure wiring is good?
how do you know it’s not working?
is the solenoid getting power? if you’re getting juice to the solenoid then the solenoid is shot.
what kind of car is this going into?
this. would be my guess considering the lack of info in your OP.
Make sure you have enough oil in the engine, sounds stupid but it could be low.
if the electronics are good and the solenoid works then its probably not getting enough oil pressure. My guess is the solenoid is either shot or not getting power.
sounds stupid, and i think one is a 1prong the other is a 2, but make sure you dont have your knock sensor plug plugged into your vtec solenoid/vis versa lol
check oil level
motor has to have run thru a heat cycle for it to engage
if you’re using a b16 ecu with the same harness, i would assume it is the solenoid then.
All plugs are pluged in the correct place the motor has also the correct amount of oil. I ran a test wire on the solenoid and it clicks but i am guessing its shot because it clicks real low.
Thank you and i appreciate the help :thumbsup
