Charcoal canister (vent valve or clogged).Here are the more common causes of P0453: If the EVAP system is not properly purging the fuel vapor, it will find other ways to escape. The only thing that you may notice is the smell of fuel. The check engine light will illuminate (that’s why you’re here). Typically, there are no symptoms associated with this code. The opposite of this code is P0452, which is thrown whenever the system pressure is too low. The fuel tank pressure sensor is typically on the top of the gas tank, fuel pump, or fuel level sending unit. This is a measure of air pressure in the tank, not fuel pressure. The fuel tank pressure sensor is what detects that the pressure in the system is too high. It uses a valve to open and close the system to release fuel vapor into the engine to be burned off. Although, we are not endorsing ignoring this code. Whether it is doing that or not, has no effect on the way your engine runs. The EVAP system is responsible for migrating fuel vapor. If the only trouble code that you have is P0453, your Grand Marquis is in no risk of breaking down. When the pressure inside of the fuel tank is too high, P0453, is thrown and the check engine light comes on. Your Mercury Grand Marquis utilizes an evaporative emissions control (EVAP) system to migrate fuel vapors from the gas tank and fuel filler neck, and sends them to the engine to be burned off.
