P0222: Accel Pedal Sensor 2 (warning lamp flashes: 16)
P0223: Accel Pedal Sensor 2 (warning lamp flashes: 16)
P0227: PTO Accel Pedal Sensor (warning lamp flashes: 61)
Generation condition Accelerator pedal position sensor 2 voltage remains less than 0.5 V for 1 second.
Recoverability
System recovers when accelerator pedal position sensor 2 voltage remains 0.5 V
or more for 1 second.
Control effected by electronic control unit
• If accelerator pedal position sensor 2 alone is faulty
Control is effected using accelerator pedal position sensor 1.
• If both accelerator pedal position sensors 1 and 2 are faulty
• Exhaust gas recirculation control is stopped.
• Auto cruise control is stopped.
• Turbocharger control is stopped.
• Control is effected using backup value (when accelerator pedal switch is
ON: accelerator pedal is not pressed (0%); when the switch is OFF: the
pedal is pressed 30%).

Generation condition
Voltage of power take-off load sensor remains less than 0.5 V for 1 second when
governor control switch is ON.
Recoverability
System recovers when voltage of power take-off load sensor remains 0.5 V or
more for 1 second when governor control switch is ON.
Control effected by electronic control unit
• When governor control switch is ON
• Engine warning lamp (orange) display
• Control is effected using backup value (output: 0%).
