P2456: 00 (PCM (H3T)) DETECTION CONDITION AND POSSIBLE CAUSE

System malfunction location	GPF pressure sensor: Output malfunction
Detection condition	Determination conditions	The PCM detects that the deviations of the maximum output value and the minimum output value of the GPF pressure sensor are less than the specified values for the specified number of times.
	Preconditions	Barometric pressure: 70 kPa {0.71 kgf/cm² , 10 psi} or more 1 Engine coolant temperature: 60°C {140°F} or more 1 Ambient air temperature: -10°C {14°F} or more 1 Engine speed: 500 rpm or more 1 The following DTCs are not detected: GPF pressure sensor: P2454: 00 or P2455: 00 GPF pressure sensor monitor basic condition are met GPF pressure sensor estimated temperature: Exceeds 20°C {68°F} The following DTCs are not detected: ECT sensor: P0116: 00, P0117: 00 or P0118: 00 IAT sensor: P0110: 00 MAF sensor: U060F: 00 *1: Standard can be verified by displaying PIDs using M-MDS
	Drive cycle	1
	Self test type	CMDTC self test
	Sensor used	GPF pressure sensor
Fail-safe	Inhibits the automatic GPF regeneration control. Inhibits the compulsory GPF regeneration control. Inhibits the fuel cut control.
Vehicle status when DTCs are output	A message related to the GPF is indicated on the display.
Possible cause	GPF pressure sensor connector or terminals malfunction GPF pressure sensor malfunction PCM malfunction
