why would my honda be throwing a(code 21) an cuttin out v tec when the light blinks code 21????

varaiable/timing

Says 21 is VTEC spool valve solenoid. To my knowledge VTEC doesn't work at all if the cel light is on.

how can i figure this problem out???it was givin me code 7 an 14 now thats fixed...

z6hatchboy

That im not sure, i dont usually here that code often so i would assume to more than likely replace it. If you dont know where it is, its in the back left-hand corner of the head on the out-side. Has a green plug on it.

could it b that my ecu is pin wrong???they sent me a po8

z6hatchboy

Maybe, p08 arent vtec i think, they have vtec conversions that solder in. But who knows if they did, ask them. Wouldn't hurt to check the pin-out though or they're soldering job.

i got the motor an ecu from h motors online...he said he didnt know??so should i try a p28??

z6hatchboy

May fix it, at least that ecu has vtec.

Just found that the P08 is the 92-95 d15b vtec ecu. I dont think the fact that its jdm will cause that CEL, so check the spool valve solenoid.
