P0496-00: (PCM - VIN Y) DETECTION CONDITION AND POSSIBLE CAUSE

System malfunction location	Evaporator system: Abnormal negative pressure in fuel tank
Detection condition	Determination conditions	Target negative pressure exceeding the specified time or more is generated from negative pressure inducted to the fuel tank by the operation of the purge solenoid valve after the fuel tank is sealed (CV solenoid valve ON).
	Preconditions	Evaporative gas flow amount: Exceeds 10, 000 cm³ /min or fuel tank vacuum is high Fuel tank pressure: -4, 340.2-4, 030.1 Pa {-442.57-410.95 kgf/m² , -0.62949 -0.58452 psi}^1 IAT sensor No. 1: 4.44-43.33°C {40.0-109.9°F}^1 Vehicle speed: 64-145 km/h {40.0-90.0 mph}^1 Barometric pressure: 72.23 kPa {0.7365 kgf/cm² , 10.48 psi} or more^1 Period ignition is switched off before engine starts: 210 min or more Fuel level in fuel tank: 15-85 %^1 Minimum value of intake manifold vacuum: 4 kPa {0.04 kgf/cm² , 0.6 psi} or more Minimum value of intake air amount: more than 2 g/sec Battery voltage: more than 11 V^1 The following DTCs are not detected: ECT sensor No. 1: P0117-00: and P0118-00: TP sensor No. 1: P0122-00: and P0123-00: TP sensor No. 2: P0222-00: and P0223-00: Purge solenoid valve: P0443-00: CV solenoid valve: P0446-00: MAF sensor: P0100-00: Fuel tank pressure sensor: P0451-00:, P0452-00: and P0453-00: IAT sensor No. 1: P0110-00: MAP sensor: P0107-00: and P0108-00: BARO sensor: P2226-00:, P2228-00: and P2229-00: VSS signal: P0500-00: Fuel gauge sender unit: P0460-00:, P0461-00:, P0462-00: and P0463-00: ^*1 : Standard can be verified by displaying PIDs using M-MDS
