Low oil level can cause this as well as a bad oil pressure switch for VTEC control, possible VTEC solenoid.
Another reason for this code is the immobilizer. the anti theft device that looks at your key for the diode to match the car. This is on cars with out the VTEC.
On the VTEC system
VTEC System Malfunction

-Low oil/pressure
-Blocked oil pressure
-Failed VCT oil control valve

Hi.. Im new to this.

dcramer531 i bought a 08' honda accord EX V6 3.0 v-tec 3 days ago. with 139,xxx miles on it. bought it with a check engine light.
took it to go get the code read and it was p1259 vtec system malfunction.

the car drives really well. fast. no idle problems. no oil leaks.
but i guess the vtec is just not engaging. when im around 35hundred RPM it sputters . thats it.. so i just drive it like a grandma.. for now..

so i hope is not a major issue..
i beeen reading forums about p1259
i keep hearing and seeing SOLENOID clean it or replace it..
and oil level which is not my case because i just got an oil change the day after i bought the car.

so how should i go about this..

theres other things i read and its possible that it can be the problem as well such o2 SENCOR? OIL PRESSURE SWITCH/VALVE?

Code P1259 what would cause this?

P1259 is the code for the VTEC pressure switch.

1. Check your oil level first, if oil level is low the code will come on. Add oil and reset the light. might have a bad Vtec oil pressure switch, try replacing it.

I have a code popping up as p1259 i have gotten some info on it i was told to get a new oil pressure switch. is that correct or what else would cause it.

Code P1259 is a VTEC System Malfunction. I don't think there's a code for a bad oil pressure switch, just an oil dash light.

p1259 is a problem with the VTEC system. this system is for improved performance at higher rpm's. oil can get sludged up and clog the system, or the VTEC solenoid can just go bad. you can always have someone with a scan tool clear the codes to turn off the light, but until the problem is fixed, it will just keep coming back on
