Does VTEC have a fuse?
VTEC is a mechanical action controlled by the ECU turning the solenoid on and off. With the engine off, try removing the fuse that powers the ECU. Leave it out for a few minutes and then replace it.
Why wont my VTEC engage?
A lack of oil pressure, enough oil or similarly related lubrication issues can cause problems with your VTEC system. Without a proper pressure reference, your big VTEC cam lobe will never get going. Without the right level of oil pressure, VTEC doesnt work.
Can you bypass a vtec solenoid?
This can be easily bypassed with a simple wiring trick: On your engine harness, locate the VTEC oil pressure switch plug/wire (this wire comes from OBD1 ECU pin D6). Do not cut the VTEC solenoid wire, simply connect the Vtec pressure switch wire to it.
Where is the VTEC system malfunction code p1259?

What to do if your VTEC system malfunctions?
Use synthetic oil, have your valves adjusted, check the solenoid operation, and if nothing else get a gasket set from Honda, it has a new screen installed, and clean the V-tec valve out. It would take just a few minutes to check the oil valve system out to make sure it can move freely, and it only has three bolts holding it in.
Can a bad oil pressure switch cause VTEC system malfunction?

Why is my Honda Accord p1259 not working?
This is facilitated by sending oil into the VTEC system, which changes the engine timing. A good rule of thumb is that if the P1259 code sets at 4000 RPM or below, it’s usually the VTEC pressure switch wiring issue or bad switch. If it is set at 4000 RPM or greater, it’ll usually be an oil related issue.

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.
