Similarly, what happens if you put too much gas in a car? Yes, overfilling your gas tank can cause damage to your car and it can cause the check engine light to come on. When you overfill your gas tank, you can get liquid gas into the vapor recovery bottle. This can damage the system, requiring parts replacements.

A: Yes, overfilling the gas tank can trigger the "Check Engine" light to come on. Modern cars are equipped with the Evaporative System that prevents gasoline vapors from escaping into the atmosphere.

Yes, overfilling the gas tank sometimes can also trigger the "check engine" light. Modern cars have what is called an Evaporative System that prevents gasoline vapors from escaping into the atmosphere.

Overfilling your gas tank can put liquid fuel into the evaporative system. Since the system is designed to deal primarily with vapors, putting liquid gasoline into the system will damage components of the system. Eventually, your check engine light will come on and you will have to effect repairs.

When you overfill your regular or diesel fuel tank too frequently, the EVAP system that is designed to process excess gasoline vapor (not the overflowing liquid) can be compromised, affecting your car’s performance and resulting in a check engine light, as well as a costly repair bill.

Overfilling your gas tank can put liquid fuel into the evaporative system. Since the system is designed to deal primarily with vapors, putting liquid gasoline into the system will damage components of the system. Eventually, your check engine light will come on and you will have to effect repairs. Stop topping off your gas tank.

The evap test system creates a vacuum in the fuel system in order to check for integrity. The cap check light comes on when there is air leak somewhere in your system - it might be tank or cap or something else. If you have replaced the cap, sometimes new caps don't fit properly and leak some air inside the tank, or you could actually have a hole in the tank, the inlet pipe, or one of the breathers.

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.

If any of these parts have degraded and release fuel vapors as a result, again, the system will sense the pressure loss and the check-engine light will come on. Overfilling the tank also causes valves in the canister to stick and release vapors into the atmosphere. The simplest solution is to make sure your gas cap is on tight.
