Why is my VTEC solenoid reading high pressure?
Looking it up in the service manual, it mentioned the VTEC pressure switch being high (meaning it was reading high pressure). My first thoughts were that it was most likely an oil issue (too much oil) or a bad pressure switch.
How does the VTEC system work on a Honda Accord?
The VTEC system controls the valve timing in your Honda. It does this by activating the VTEC/Rocker arm solenoid. It uses the Rocker Arm oil pressure switch to monitor the pressure of this system. P1259 specifically means that there is an issue with the VTEC circuit itself. Although, mechanical issues can cause the code to register as well.
Why does my Honda Accord have variable valve timing?
