Why is my p1259 VTEC code not working?
Take a moment to enter our new BBQ contest here for a chance to win a $400 Walmart gift card! I’d been getting a P1259 for some time and ruled out the oil level. It just wouldn’t go away so I bit the bullet and rolled up my sleeves. I replaced the gasket and found the old one pretty full and clogged.
How does the PCM monitor the VTEC system?
The PCM monitors oil pressure conditions in the hydraulic circuit of the VTEC mechanism according to the VTEC oil pressure switch downstream of the VTEC solenoid valve.
Why does my Honda CRV have a p1259 code?
I’d been getting a P1259 for some time and ruled out the oil level. It just wouldn’t go away so I bit the bullet and rolled up my sleeves. I replaced the gasket and found the old one pretty full and clogged. It was a pain in the butt to get to, but I managed to do it. Was pretty happy until about a day after, the code resurfaced.
Where is the VTEC system malfunction code p1259?
Re: VTEC System Malfunction code P1259 has appeared. (… Check your variable valve timing oil pressure switch, it’s located on the passanger side just before the intake manifold, also the solenoid may be dirty or bad. some people say to clean the screen but that requires removing the entire assembly where these two units are… Good luck
What is the trouble code for Honda VTEC?

What causes a VTEC system to malfunction?
NOTE: While there are some exceptions, the general rule is that if the code sets at, or just above idling speeds, the fault is caused by a general electrical issue, while if the code sets above about 4000 RPM, the fault almost invariably involves insufficient oil pressure, or a failure of the VTEC oil pressure sensor. None found.
What is the error code for a VTEC oil pressure switch?
The PCM will oversee the system and should there be any disparity between the oil pressure condition in the hydraulic circuit determined by the PCM command, and the oil pressure determined by the status of the VTEC oil pressure switch, then this system will be read as a fault, setting the code P1259.
