Hey guys/gals new to your forums been browsing them for quite some time now never thought i would have to register. I have one problem with this mini me setup i have build for some reason i cannot get vtec to work. It is a d15b1 block with a d16y8 head i have never really messed with these single cams before Im actually pretty tech savy i am pulling a code for the vtec solenoid and pressure switch. I have tried replacing these with no suck luck still. When doing the build i followed the whole manuel i was using to a T i removed the oil jet from the d15 block as stated in the manuel and left the jet in the d16y8 head. Some suggestions would be nice if you need more info just ask thanks for your time.

 

did you run the wires on the right spot on the ecu?

 

as stated, did you run the wires for vtec correctly?

 

x2

 

this is for if you have a 92-95 Civic.

 

Ya im sure the wires are ran correctly i have checked them over and over the car was origanally a vtec car still has the vtec ecu harness and the engine harness is from the 1.6 vtec also and i have a p28 ecu running it im lost

 

what year is the car?

 

x2 on that if its a older dx u have to do a mpfi swap

 

It's a 94 ex originally came with a 1.6 vtec the kid totally trashed it got a good deal on this 1.5 block and vtec head only gave 200 bucks for everything the only reason i went ahead and done this mini me or else i would have just went back with the original 1.6 vtec but im having a feeling i would have ran into the vtec issues with that motor also if i would have installed it.

 

and your POSITIVE you ran the wires correctally? check the grounds?

 

are you getting any cels? ..
grounds are nice and solid?
what ecu are you running?

check the harness for broken wires from the switch all the way to the ecu?

 

he didn't have to run them, he used the vtec engine harness, so are both codes coming up?? 21 and 22?

 

Yes you are right i didn't have to run anywires becuase the car and harness was already vtec i am gettin a 21 and 22 code and i was wrong about the ecu it isn't a p28 it is a p07 just found that tonight but still a vtec ecu got that ecu with this head

 

Don't know if it helps any but i did hook that p07 ecu up to my integra that i have a b18c1 in and the vtec did work only thing that sucked was rev limiter was like 6600 lol and it wasn't throwing any codes either when hooked up to the gsr

 

take and unplug the vtec solenoid and put a wire to the pin on the inside of there(to the one to the solenoid) then touch that wire to the positive side on the battery and see if you hear a click. If you do hear the click then the solenoid is fine and it's just the wiring somewhere, but if it doesn't click then change out the solenoid and pressure switch. but since you have checked the ecu, then you may have gotten a bad solenoid and pressure switch. also have you checked your oil? I know low oil level could set off the pressure switch code, but it shouldn't have an effect on the solenoid.

 

Also, did you check to make sure you have your ground connected for the solenoid? on the Vtec engine harness where the pressure switch plugs there should be the ground also to bolt up.

 

I will check that stuff out tomorrow i appriciate your guy's help man i been lost on this thing for a bit i will also ohm the wires out from the fire wall to the ecu make sure they arent broke some where in between

 

Ok thanks guys dunno why i over looked it but yes was the ground wire for the vtec thanks for all your help sometimes it's nice to have someone elses opinion or insight

 

i'm glad you got it fixed .. glad we all could help ya.

 

another car fixed by honda -tech
