Top Makes and Models with DTC P0456

Toyota fans will be surprised to learn that the Camry and Corolla are at the top of the list of vehicles with the most frequent occurrence of diagnostic trouble code (DTC) P0456. FIXD sensor data also reveal that other high-ranking offenders include the Ram 1500 pickup, the Jeep Grand Cherokee, and the Jeep Wrangler. 

These brands continue to have a strong but less elevated P0456 code presence with the Toyota 4Runner and Jeep Liberty. Other Chrysler (now Stellantis) products with moderate P0456 occurrence levels include the Dodge Charger, Dodge Durango, and Dodge Ram 1500. The Chrysler Town & Country minivan is no stranger to this issue either.

Owners or buyers of a Ford Escape, Edge, Focus, or Fusion should be aware that these vehicles have a history with this DTC. The same applies to the Nissan Maxima, Murano, Rogue, and Sentra. However, code P0456 troubles aren’t limited to American and Japanese brands. The Volkswagen Jetta also appears on this list.

There are notable absences from this index, too. According to FIXD research, two of America’s most popular vehicles, the Ford F-150 and Chevrolet Silverado 1500, don’t have issues with DTC P0456. 

Keep reading as we cover the top makes and models prone to code P0456 instances. These year-by-year details look at low, moderate, or high occurrences and are based on a broad spectrum of model years, from 2000 through 2023, and vehicles with installed FIXD sensors.  

What is Code P0456?

In simple terms, DTC P0456 involves a small leak in the evaporative emission control (EVAP) system. Fortunately, this problem doesn’t require rushing to a mechanic or stopping the car. However, it should still be addressed and not ignored. Failing to fix this trouble can lead to a persistent check engine light, poor fuel economy, increased emissions, and a gas aroma. 

The cause of a P0456 error code can range from a troublesome gas cap to a faulty EVAP system charcoal canister.
