My car has been throwing a code 21 and my check engine light is on. My Vtec is also not working. A few people have been telling me that my vtec solenoid went out. Is that the problem? I 've been calling around for a vtec solenoid and used ones are impossible to find. A new one from the dealership is like 300 dollars. If anyone had an extra b series motor with a vtec solenoid to sell me then just im me and let me know please. Thanks.

 

Are you sure your vtec sol. is out?

 

yes, 21 is vtec solenoid. Its the wiring, or the solenoid. is it a fresh swap? or has it been in for a while with no codes. Ryan

 

I was talking about if the actual silenoid was that he has to buy another one. you can test it by checkin continuity. you stick one probe into the solenoid plug and the other to a good ground. it should read between 14-30 if it's good. above or below that it's bad.
