P2229: Atm Press SNSR (High) (warning lamp flashes: 19)
P2263: VGT System (warning lamp flashes: 51, 54)
P2279: Intake Pipe Leak (warning lamp flashes: 27)
P2413: EGR System (warning lamp flashes: 67)
Generation condition
Voltage of atmospheric pressure sensor (inside engine electronic control unit) is
higher than specification (4.7 V).
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 atmospheric pressure sensor
• Malfunction of engine electronic control unit
Generation condition Turbocharger system is abnormal.
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
• Fuel injection rate is limited.
• Turbocharger target opening value is replaced by a backup value.
• Exhaust gas recirculation control is stopped.
• Intake throttle 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 Air leakage occurs in intake air system.
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
• Foreign substances deposited on intercooler front core
• Intercooler air leakage
• Air inlet hose/air inlet pipe fitted poorly
Generation condition Exhaust gas recirculation system abnormal
