The present disclosure provides diagnostics for a fuel tank heating system. A vehicle includes a fuel tank, a canister, a first valve, a second valve, a heater, and a controller. The fuel tank is configured to store fuel. The canister is in fluid communication with the fuel tank and is configured to receive and store evaporated fuel from the fuel tank. The first valve is disposed between the fuel tank and the canister. The second valve is disposed between the canister and the ambient environment. And the heater is arranged in the filter tank. The controller is programmed to periodically initiate a diagnostic test configured to determine whether the heater is normally operating, whether the heater cannot be turned off, or whether the heater cannot be turned on.

    本公开提供了“用于燃料罐加热系统的诊断”。一种车辆包括燃料箱、滤罐、第一阀、第二阀、加热器和控制器。所述燃料箱被配置为存储燃料。所述滤罐与所述燃料箱流体连通并且被配置为接收和存储来自所述燃料箱的蒸发燃料。所述第一阀设置在所述燃料箱与所述滤罐之间。所述第二阀设置在所述滤罐与周围环境之间。所述加热器设置在所述滤罐内。所述控制器被编程为定期地发起诊断测试,所述诊断测试被配置为确定所述加热器是否正常操作、所述加热器是否无法关闭、或者所述加热器是否无法开启。
