Hi i have a integra GSR B18C and my vtec stop working. what can be the problem?? What do i have to check to put it work again?? HELP PLEASE

 

Any check engine codes?

 

Do you have any oil leaks on the motor? If so, could be causing enough of a drop in oil pressure for vtec to not work.

Check your oil and make sure its not low as well.

Added that link to the faq.

 

i got code 21

 

code 21 = VTEC solenoid

You can try to change it. or just chang the oil pressure switch also if its a swap make sure the yellow/green wire is wired up correctly from the VTEC solenoid all the way to your ecu.Also make sure your not low in oil.

BTW vtec wouldnt work if the car is too cold drive it of a lil and check i it works.

GOOD LUCK

 

g/l finding information, if its your vtec solenoid, try the plug, wiring or replacing the top piece.
