Question

2002 Honda CRV 4 Cyl, what does VTEC system failure mean? I got the engine codes P1259 and P0420

Answer 1

P1259 VTEC system malfunction

This is a malfunction of the VTEC oil pressure switch, this can be from low oil,Because the component in question has a high rate of failure,play it safe,just replace the VTEC solenoid valve, the VTEC oil pressure switch,that or you will buy cylinder head.
