(12) Rail Pressure Sensor Abnormality (DTC P0192 / 157-4, P0193 / 157-3)

P0192 / 157-4: Rail pressure sensor abnormality (Low side)
Behaviour during malfunction:

• Insufficient output
• Worsening exhaust gas performance
• Worsening running noise
• Increase in white smoke
• Engine stops

Detection item:

• Ground short circuit of sensor / harness
• Failure of sensor

DTC set preconditions:

• Battery voltage is normal
• Sensor supply voltage VCC# is normal

DTC set parameter:

• Voltage of rail pressure sensor is 0.7 V or less

Engine warning light:

• ON

System action:

• Output limitation: Approximately 50 % of normal condition
• Speed limitation (Accelerator limitation: 50 %)
• Rail pressure limitation: Command pressure

≤

80 MPa (820 kgf/cm

2

, 12000 psi)

• EGR stop
• Engine forcibly stopped 60 sec. later

Recovery from error:

• Key switch turn OFF

9Y1200192CRS0695US0

P0193 / 157-3: Rail pressure sensor abnormality (High side)
Behaviour during malfunction:

• Speed limitation (Accelerator limitation: 50 %)
• Rail pressure limitation: Command pressure

≤

80 MPa (820 kgf/cm

2

, 12000 psi)

• EGR stop
• Engine forcibly stopped 60 sec. later

Recovery from error:

• Key switch turn OFF
