P2151: Injector Bank 2 (High) (warning lamp flashes: 82)
P2199: EGR Temp Sensor (Correlation) (warning lamp flashes: 9)
P2227: Atm Press SNSR (Plausibility) (warning lamp flashes: 19)
P2228: Atm Press SNSR (Low) (warning lamp flashes: 19)
Generation condition Injector magnetic valve (No. 2 and No. 3 cylinder) circuit shorted to power supply.
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.
• Outputs injection control fault signal through CAN bus.
• Injector magnetic valves (No. 2 and No. 3 cylinders) are stopped.
• Exhaust gas recirculation control is stopped.
• Throttle control is stopped.
Possible causes
• Open-circuited or short-circuited harness between engine electronic control
unit and injector magnetic valve (cylinder 2, 3)
• Malfunction of each connector
• Malfunction of injector magnetic valve (cylinder 2, 3)
• Malfunction of engine electronic control unit
Generation condition
The exhaust gas recirculation temperature sensor was judged faulty based on
the diagnostic results obtained by comparing boost temperature sensor and in-
take air temperature sensor outputs.

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 Intake air temperature sensor
• Open-circuit or short-circuit of harness between engine electronic control unit
and Boost air temperature sensor
• Malfunction of each connector
• Malfunction of Intake air temperature sensor
• Malfunction of Boost air temperature sensor
• Malfunction of engine electronic control unit
Generation condition
The engine electronic control unit has judged that the atmospheric pressure sen-

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

Possible causes
• Malfunction of atmospheric pressure sensor (inside engine electronic control
unit)
• Malfunction of Boost pressure sensor
• Malfunction of engine electronic control unit
Generation condition
Voltage of atmospheric pressure sensor (inside engine electronic control unit) is
lower than specification (0.19 V).
