I figured this would pertain a little bit more to you eg/ek guys so ill try here.

I have just recently conquered my last ecu code last night (01 O2 sensor), And today on my drive home from work i have received another CEL. This time i check it out and see that it is a Code 21. I searched for a bit, but yeilded no results. Is this a frequent code that people get? what is the fix? i dont even know where to begin.... Please help. Thanks

Also i noticed on my way home the car wasnt going into vtec (i think).... Let me know

21 = vtec solenoid, it could be few issues:
1) check wiring make sure its in the right location and you're not confusing this with vtec oil pressure solenoid
2) make sure you have oil and the sensor gets oil
3) make sure sensor is in working condition

 

21
VTEC Solenoid (VTS)
i have one.....pm me for price

 

ok im gonna run through that list tonite after work. Thanks for the help

 

To Run through this List:
21 = vtec solenoid, it could be few issues:
1) check wiring make sure its in the right location and you're not confusing this with vtec oil pressure solenoid
2) make sure you have oil and the sensor gets oil
3) make sure sensor is in working condition <<< How do i test this??

 

well you could test that the vtec solenoid is workin by clickin it with a positive and negative if it clicks is working

 

yea that is what i have read, but what do you connect to the pos and to the neg??

theres only 1 wire that goes into the solenoid!?

 

cant any1 tell me how to test the vtec solenoid, in laymens terms, which wire to connect to +12v

 

pm'd ya.......

 

if it is still on the car..it is already grounded man.....
