Hey everyone, I have a 94 prelude with a jdm h22a and the car runs fine until it gets up around 100mph. When it reaches this speed the car just completely looses its vtec power and the check engine light comes on. I pull the code and its 22 which is oil pressure switch. I dont know what could be causing this so if anybody knows please help.

 

Check the Vtec solenoid. Mine did this too and it turned out to be a clogged screen in the solenoid.

 

Also check your oil level.

 

i would like to know why your goin 100mph first

 

whatever, it's not working right.
Check your wiring.

 

Let me know b/c I am loosing vtec after 7k rpm also!!
