What is the code for the oil pressure switch on a Honda Accord?
Engine hesitated while accelerating from a stop. The check engine light (CEL) came on immediately. Autozone pulled the code of P2647. I replaced the oil pressure switch (37250-PNE-G01) and the o-ring (91319-PAA-A01).
Why is the solenoid on my Honda Accord leaking oil?
On many Honda vehicles, the VTEC solenoid has been found to be the culprit. More commonly, the gasket could be faulty and all that needs replacing. When this solenoid is bad, the motor’s VTEC will not “activate.”. It is largely dependent on the engine’s oil pressure and engine temperature.
What causes the solenoid not to activate VTEC?
If the motor is not maintaining oil pressure or reaching engine temperatures, it can cause the solenoid to fail and not activate VTEC. With the engine cool, pull the dipstick and make sure the oil level is not low. By reading the temperature gauge, when the car is running, we want to make sure it reaches 178 degrees.
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.

What should I do if my solenoid is seeping oil?
Visually inspect the solenoid, oil pan, and oil pressure switch areas for seeping oil. Confirm that VTEC “activates” at 178 degrees. If VTEC does not activate, it may be necessary to replace the solenoid itself.
How does the variable valve timing and lift ( VTEC ) system work?
The Variable Valve Timing and Lift Electronic Control (VTEC) system activate the VTEC solenoid valve by the command from the Powertrain Control Module ( PCM ), and it charges/discharges the hydraulic circuit of the VTEC mechanism that is installed in the valve system to switch valve timing between Low and High.
