DTC P0496-00: (PCM, VIN M) DETECTION CONDITION AND POSSIBLE CAUSE

DESCRIPTION	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: above 72.23 kPa {0.7365 kgf/cm² , 10.48 psi}^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: above 2 g/sec Battery voltage: above 11V^1 The following DTCs are not detected: ECT sensor: P0117-00:, P0118-00: TP sensor No. 1: P0122-00:, P0123-00: TP sensor No. 2: P0222-00:, P0223-00: Purge solenoid valve: P0443-00: CV solenoid valve: P0446-00: MAF sensor: P0100-00: Fuel tank pressure sensor: P0451-00:, P0452-00:, P0453-00: IAT sensor No. 1: P0110-00: MAP sensor: P0069-00:, P0107-00:, P0108-00: BARO sensor: P2226-00:, P2228-00:, P2229-00: VSS signal: P0500-00: Fuel gauge sender unit: P0460-00:, P0461-00:, P0462-00:, P0463-00: ^*1 : Standard can be verified by displaying PIDs using M-MDS
