where is the vtec pressure valve what possibilities are there that could have gone wrong with it...I reseted the ECU and the light is off, but Im betting it will throw the code out again... BTW could faulty wiring from a VAFC cause this...I sodered the wires and followed the directions thoroughly..

 

BTW after the engine light came on the VTEC was still working properly...the car was working very well and running strong...could someone direct me to where exactly the vtec pressure valve is...BTW unhooked the ECU and after a couple hours the light is still off....but im still a lil hesitant...thx a lot

 

The VTEC oil pressure switch is #15, but I think code 22 might also be caused by low oil pressure, not necessarily a bad switch.


The VTEC solenoid valve is #13, but that would be code 21.
