i have a 95 civic ex coupe with a mini me swap that is a d15b7 bottom end, and d16z6 top end. i am getting a cel. the code i am receiving is 22 (vtec pressure switch). i have swapped the vtec solenoid out 3 different times. and the only thing that i can think of is it is not getting enough oil to the head. but iirc the b7 and z6 have the same oil pumps. can someone help me trouble shoot this problem.

 

need help!

 

help!

 

ttt

 

help me

 

which ecu are you using? try jumping pin A4 and D6.

 

i have a p28 mt ecu

 

did you did follow the many write ups on how to get oil into the head for the VTEC solenoid?

 

There is a oil restrictor in the middle of the cylinders on D motors. You have to remove this when doing a mini me. vtec swap. That is most likely the problem .

if not you can get the ecu chiped to not look for the oil pressure sensor.. ?

 

yes i have read the many write ups for the mini me swap and i pulled the oil restricter out. the car has ran a year with no problems and this happens.

 

still need help!

 

still waiting on some help/

 

could it be possible that i have a bad oil pressure switch

 

did you double check your wiring. maybe a wire is messed up at the ecu.

look up how to bypass vtec oil pressure. that might give you a option

 

cool, and i am using a the z6 harness. do you think that it still may be messed up?

 

what would this do?

 

i need some help/

 

you better make sure that all your wiring is soldered together so you dont have any loose or bad connection cause that happens alot make sure your connections are soldered together then heat shrink it might work

 

this is a uncut harness.

 

vtec is fixed. i bought a new oil pressure switch fir the vtec solenoid and now vtec is working and my cel is gone. but i still have the idle surge.
