Details On DTCs

WARNING: This page is about a different car, the 2016 Mazda CX-5. However, it is still accessible from the selected car via links, so may be relevant.

DESCRIPTION	Evaporator system: clogging between fuel tank and fuel tank pressure sensor
DETECTION CONDITION	Determination conditions	The following conditions are all met while the vehicle is being driven: If negative pressure is inducted to the fuel tank via the intake manifold by the operation of the purge solenoid valve with the fuel tank in a sealed condition and the target negative pressure is reached within a shorter period of time than the estimated time. When the barometric pressure in the fuel tank is fixed and the purge solenoid valve is opened/closed, the negative pressure fluctuation in the fuel tank generates negative pressure exceeding the threshold.
	Preconditions	Period ignition is switched off before engine is started: 120 min or more Engine coolant temperature at engine start: 1.67-43.33 °C {35.1-109.9 °F} ^1 Time elapsed from engine start: 5.5-90 min Fuel level in fuel tank: 10-90 % ^1 Desired ambient air temperature: 4.4-43.3 °C {40-109 °F} ^1 Barometric pressure: 72.23 Pa {7.365 kgf/m ² , 0.01048 psi} or more ^1 Charging efficiency: 3-65 % ^1 Vehicle speed: 64-144.8 km/h {40.00-89.97 mph} ^1 Purge flow amount: 15 l/min or more ^*1 : Value can be verified by displaying PIDs using M-MDS
