V3800-CR-TE4,V3800-CR-TIE4, DM

(3) Pressure Limiter Emergency Open (DTC P0087 / 633-7)

Behaviour during malfunction:

• Insufficient output
• Worsening exhaust gas performance
Detection item:
• Open circuit or +B short circuit of sensor / harness

DTC set preconditions:

• Rail pressure sensor is normal
• Sensor supply voltage VCC# is normal

DTC set parameter:

• Combination of below A and B
A: Fuel leak (P0093) is detected
B: Condition (1) or (2) is fulfilled;
(1) Rail pressure exceeds 191 MPa (1950 kgf/cm
(2) Within 1 sec, after the rail pressure goes below 191 MPa (1950 kgf/cm
[Before the pressure decrease, the rail pressure is above 191 MPa (1950 kgf/cm
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
• EGR stop

Recovery from error:

• Key switch turn OFF
