my check engine light came on and the code that said what was wrong with it was P1259 which means a VTEC malfunction. so its either my oil pressure switch is bad or the vtec solenoid. what should i do? should i jus buy a new VTEC solenoid that comes with a new switch. should that fix everything?

I drive a B16 99 honda civic si

 

just fix everything. It shouldnt be that hard to do it. Get it out of the way
