so i've finished a swap of a b16 into a 91 crx si and everything went fine. I've even taken care of the code 6 and 7 check engine lights. for some reason though, the vtec still does not kick in. I have enough oil, my speedo works, I waited until it was up to tempurature and it still does not work, even without any check engine lights. anyone have any ideas? Any help would be great.

 

is your solenoid clean? I am going through this now also

 

what ecu?

 

1) Oil level, its gotta be FULL. I'm talking at the upper mark on the dipstick.

2) Solenoid, Ok this is a 2 parter. A) take a wire (any wire) disconnect the grey plug on the vtec solenoid and touch the wire to the pos. battery terminal and the solenoid side of the grey 1 pin connector. there should be an audible click from the solenoid. B) If A checks out, remove the solenoid and clean the filter screen. (self explanatory)

3) Speed, the car must be going over 10 mph so the speedo must be working. that means the VSS has to be working. vtec is temperamental isn't it?

4) more oil, check the oil pan. if its dented POUND IT OUT!.


5) ECU Swap out to another ECU that you KNOW vtec works on.

6) Car must be at I belive its 80 degrees or higher so let car get to a normal operating temprature.

7) If none of the above work, you might want to pull the solenoid off the head, remove the solenoid filter and verify the piston moves freely.

I got a D16z6 SOHC VTEC in my 92 Civic EX, and my VTEC is not working either. My friend's VTEC is real loud in his Civic EX, and his car is fully stock. I got an AEM Cold Air Intake, and was told I should be able to hear the VTEC better with an intake, but I don't hear or feel any difference. Can someone please help me out? E-mail me at: crazeone69@aol.com I just actually found out that I had VTEC a few days ago, but I just want it to work.

Thanks Everyone,
Tyson
