Q: My Check Engine Light is on after the fuel tank overflowed

asked by on

When the fuel overflowed, the fuel system most likely caused the vapor recovery and tank vent to become flooded with liquid fuel. This flooding of the vent system may cause the computer to sense a problem in the fuel tank and purge valve function and set a code, turning on the Check Engine Light.

You will need to have the Check Engine Light diagnosed and any codes received cleared from memory, and then must drive the vehicle to see if the code returns. If the light does not come back on, then you may not have damaged anything by overfilling the fuel tank. If the light comes back on, then one of the fuel tank vapor system components may need to be replaced. I recommend having a certified mechanic, such as one from YourMechanic, come to your location to determine why the Check Engine Light is on and what repairs are necessary.
