00' Si throwin the VTEC malfunction code ....H E L P

 

. . . . On h0w to fix>

 

Its an oil switch I believe. The VTEC oil pressure switch is a normally closed switch. The ECM sends a voltage to the switch and expects the voltage to go through the switch to ground. If the ECM reads a voltage on that circuit when the VTEC system should not be operating, it will turn on the "check engine" light and set a code. This code will be a P1259 on a vehicle with OBD-II.

You can buy a new switch from http://www.hondaautomotiveparts.com for about 43 bucks.

Replace the switch. Its as easy as that.
