(52) Differential Pressure Sensor Abnormality (DTC P2454 / 3251-4, P2455 /
3251-3 (PCD))
P2454 / 3251-4: Differential pressure sensor 1:Low
Behaviour during malfunction:
• None
Detection item:
• Ground short circuit of sensor / harness
DTC set preconditions:
• Battery voltage is normal
• Sensor supply voltage VCC# is normal
• Starter Switch signal (Engine ECU: V12 terminal) is not activated
DTC set parameter:
• Differential pressure sensor voltage: 0.21 V or less
Engine warning light:
• ON
Limp home action by engine ECU (system action):
2
• 0 kPa (0.0 kgf/cm , 0.0 psi) [default value]
• Output limitation: Approximately 75 % of normal condition
Recovery from error:
• Key switch turn OFF
