what kind of computer are you running ? check the v-tec wiring

im running a p28 tuned and ill chech the wiring aagin...but shouldnt vtec come on if i rev the engine to 5500 rpms and manually open the solenoid by putting the wire on the battery terminal b+

im running a p28 tuned and ill check the wiring again...but shouldnt vtec engage if i rev the engine to 5500 rpms and manually engage the solenoid by putting the wire to the b+ of the battery if not tell me how i can solve this dalima or if there is other ways of "popping" vtec....thanks

is your check engine light on?

Re: (HondaCivicSiR1)
 

no check engine light or anything i dont know what is going on?????? if you know certain procedures on how to fix this problem the let me know it would be very appreicited!!!thanks

Re: (turboh22civic)
 

see if you can get you hands on stock ecu. try stock p28 or p30. and see if v-tec pops with those stock ecu's

Re: (rpared01)
 

i would try a a 94-95 gsr p72 or a prelude p13 ecu.

Re: (HondaCivicSiR1)
 

ive tried stock p13 and the p28 untuned and well i was like mabe it was needing tuning but it still doesnt come on...do i have to have the vtec pressure switch hooked up.. for example if we were tuning the car at the time and the guy made it were i didint need the pressure switch is that ok????if i need the vtec oil pressure switch on let me know we will try that!!! shouldnt the vtec solenoid "pop" if i reved the engine to 5500 rpms and here vtec or should it be driving and then manullly try to engage vtec with a switch or something at 5500 rpms.... let me know!!!! i think the pressure switch needs to be hooked up but do let me know if i dont need that or something since its a swap and all....!!!.................I WAS WANTING TO KN0W AS WELL IF THE VTEC WONT KICK ON BECAUSE SOMETHING COULD BE CLOGGED OR SOMETHING IN THE CYLINDER HEAD.. IF SO LET ME KNOW SOME DETAILS ON HOW I CAN FIX IT IF YOU OR ANYONE KNOWS HOW TO FIND WAYS OF FIXING OR "POPPING" VTEC I WOULD LIKE TO KNOW AND I WOULD BE VERY APPRECIATED!!!!!! THANKS AGAIN AND I LOOK FORWARD FOR SOME GOOD COMMENTS!!! https://honda-tech.com/forums/images...es/emsmile.gif

its your v tec solenoid,it should hear a click when you put the single grn/ylw wire to b+ terminal

Re: (h2b ef sedan)
 

No its not your solenoid - (to the above poster he did say he heard it click, in the 1st post). Yes, the VTEC Oil Pressure Switch MUST be hooked up for VTEC to work because it works with oil pressure as well. If its not connected vtec will not work because the ecu thinks you have low oil pressure or no oil pressure.

Also make sure you have enough motor oil in your engine - not enough oil = lower oil pressure = vtec pressure switch not activating = no vtec https://honda-tech.com/forums/images...s/emsmileo.gif

Hope this helps ya cos I had the same problem once https://honda-tech.com/forums/images/smilies/emwink.gif

HOLY SHIT..MAN IT WORKED!!!!!!!!! YOU WERE RIGHT I MADE IT TO WERE THE PRESSURE SWITCH WAS READING OIL PRESSURE AND GUESS WHAT???.... I POPPED VTEC......F@#$% SWEET...THANKS MAN FOR YOUR KNOW HOW!!! https://honda-tech.com/forums/images...es/emsmile.gif https://honda-tech.com/forums/images...s/emsmilep.gif https://honda-tech.com/forums/images/smilies/emthup.gif
