ok so i did a gsr swap in my Eg hatch and now im having vtec issues. I am getting Cel 21 thats t6he spool valve also knowen as the vtec solenoid. I did all my continuity checks and everything is good. I am running a chipped P06 that i got done by Shawn at Ramey built so i know thats good.i wired everything up to the right spots on the ecu harness.
I am not getting any power to the oil pressure side of the vtec switch wich is good but as soon as i turn the key on im getting 12v to the soleniod is this right? Some one help me out here im running out of ideas

 

id have to look at it to supply any help, but if I had a dollar for everytime someone made a thread for vtec probs, id be rich. pm me if you want me to come help out after the weather clears

 

thanks man pmed. by the way i didnt mention that oil pressure is good and i have my knock sensor and o2 sensors deleted on the ecu

 

If I remember, the ECU sources 12V to the solenoid, and the solenoid is ground referenced, so you shouldn't have anything on that wire until VTEC engages.

 

ok thats what i thought ill play with it some more tomorrow

 

still no luck i even rechecked the hook up of the wires to the ecu harness and its fine. I know i have them in the right spots cause the last swap i did i used the same diagram. Any help please im drawing a blank

 

is the soleniod itself bad?

 

no i even tested it by putting a 12v sorce to it and it clicks so that leads me to belive that its good

 

update: so i hooked my ecu up in my boys car and it did the same thing looks like i have ecu problems. the only thing is that i took his good ecu and vtec solenoid and now i have another problem. now the car drives great no cel till i hit 6500 prms and the same one for the solenoid one comes on. i know the stuff im using from his car is good cause it all worked before i took it out his car and after i put it all back in. damn i just stumpped please help

 

So you put a known-good ECU in the car, and it works but you get a solenoid CEL. Therefore you have a solenoid (or solenoid wiring) problem. I'm assuming the ECU is doing fault detection when it tries to activate the solenoid, which many/most ECUs do.

Anyway, it sounds like you know where to look.
