Most likely it means your gas cap is loose... or whats called an evap system leak.
Trouble code P0457 means:Evaporative emission control system leak detected ( Fuel cap loose/off)
Trouble code P0457 indicates a "Evaporative Emission Control System Leak Detected (Fuel Cap Loose/Off)." This code is triggered when the vehicle's onboard diagnostic system detects a leak in the evaporative emissions system, often due to a loose or missing fuel cap. It can lead to increased emissions and may affect fuel efficiency. Resolving this code typically involves checking the fuel cap and the surrounding components for any leaks or damage.
P0457 Evaporative Emission Control System Leak DetectedIt means there is a vapor leak between the gas cap, tank, and engine.P0457 Evaporative Emission Control System Leak DetectedIt means there is a vapor leak between the gas cap, tank, and engine.
For a Buick Enclave, the engine codes mean the following: P0642: This code indicates a problem with the sensor reference voltage circuit. P0451: This code points to an issue with the evaporative emission control system pressure sensor range/performance. P0457: This signifies a leak detected in the evaporative emission control system, specifically related to the gas cap. P0193: This code indicates a high input from the fuel rail pressure sensor. P0195: This code suggests a high input from the fuel temperature sensor. These codes may require diagnostic testing to pinpoint the exact cause and necessary repairs.
