Problem overview
Many Honda Accord owners have noticed their vehicle failing to accelerate, especially when attempting to accelerate quickly. Also, the check engine light will illuminate, and the engine control module (ECM) will store trouble codes pertaining to the VTEC solenoid or pressure switch.
A broad selection of Honda vehicles equipped with VTEC are known to leak engine oil at the VTEC oil pressure switch, and this will cause the symptoms noted above.
The switch is mounted with a gasket to prevent oil leaks, but fails at random intervals, normally sometime after the 100,000 mile mark.
Replacing the gasket, a small screen, and possibly the oil pressure switch will be necessary if this leak has occurred.
