13E-22
P0047: VGT Actuator (Low) (warning lamp flashes: 51)
P0069: Boost Press SNSR (Correlation) (warning lamp flashes: 32)
P0087: CRS (Too Low) (warning lamp flashes: 22, 36)
P0088: CRS (Too High) (warning lamp flashes: 23)
Generation condition Turbocharger actuator circuit is shorted to ground.
Recoverability
System recovers if any valid signal is input when starter switch is turned from
OFF to ON (the warning lamp does not go out unless 3 consecutive valid signals
are input).
Control effected by electronic control unit
• Injection quantity is limited.
• Exhaust gas recirculation control is stopped.
• Throttle control is stopped.
• Turbocharger control is stopped.
Possible causes
• Open-circuit or short-circuit of harness between electronic drive unit and tur-
bocharger actuator
• Malfunction of each connector
• Malfunction of motor (built in turbocharger actuator)
• Malfunction of position sensor (built in turbocharger actuator)
• Malfunction of electronic drive unit
• Malfunction of electronic drive unit relay
Generation condition
Engine electronic control unit has judged boost pressure sensor abnormal as a
result of comparison with conditions of other sensors.
Recoverability
System recovers if any valid signal is input when starter switch is turned from
OFF to ON (the warning lamp does not go out unless 3 consecutive valid signals
are input).
Control effected by electronic control unit
• Injection quantity is limited.
• Exhaust gas recirculation control is stopped.
• Throttle control is stopped.
Possible causes
• Open-circuit or short-circuit of harness between engine electronic control unit
and Boost pressure sensor
• Malfunction of each connector
• Malfunction of Boost pressure sensor
• Malfunction of engine electronic control unit
Generation condition Common rail pressure too low
Recoverability
System recovers if any valid signal is input when starter switch is turned from
OFF to ON (the warning lamp does not go out unless 3 consecutive valid signals
are input).
Control effected by electronic control unit
• Injection quantity is limited.
• Exhaust gas recirculation control is stopped.
• Throttle control is stopped.
Possible causes
• Malfunction of supply pump
• Malfunction of pressure limiter
• Injector not airtight
• Clogged fuel system
Generation condition Common rail pressure too high

are input).
Control effected by electronic control unit
• Injection quantity is limited.
