Ok now my v-tec doesn't work anymore. I got a code 21. How do i fix the problem? Sometimes the check engine light goes away and it comes back on? Must be something loose but i can't figure out what though. Please help?I have b16 crx. Thanks

 

you have either a bad vtec solenoid or bad circuit or not hooked up circuit. you can test the solenoid, you have to get a manual and a volt meter for the test procedure. I don't have a scanner to show you. good luck.

 

Hey already fixed it. The wire was loose. Thanks for ur help though
