Answer 1

I don't know what the year of the vehicle is so I can't be too specific; the usual cause for VTEC problems is a very low oil level in the engine. check that first. If the level is low, top it off and then pull the back up fuse in the underhood fuse box to clear the code (you didn't mention if you did that after replacing the solenoids--it could be that is all you need to do). run the engine and see if the code returns. If it is not the oil level or the solenoid, then keep in mind that electrical problems that are not cured by replacing the part are usually caused by bad connections so look for terminals in the connector that are pushed back or corroded.

hope that helps. if you need more information, give us the year and model of the car to get more specific.

Answer 2

if you changed 3 its not your problem check voltage
