P0228: PTO Accel Sensor (warning lamp flashes: 61)
P0237: Boost Press SNSR (Low) (warning lamp flashes: 32)
P0238: Boost Press SNSR (High) (warning lamp flashes: 32)
Generation condition
Voltage of power take-off load sensor remains higher than 3.5 V for 1 second
when governor control switch is ON.
Recoverability
System recovers when voltage of power take-off load sensor remains 3.5 V or
less 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%).

Generation condition Boost pressure sensor voltage remains less than 0.3 V for 3 seconds.
Recoverability
System recovers when boost pressure sensor voltage remains 0.3 V or more for
1 second.
Control effected by electronic control unit
• Control is effected using backup value of 101.3 kPa {1.03 kgf/cm
2
}. (Output is
reduced, and fuel economy worsens.)
• Actuator test “BA: VGT Test” is stopped.

Generation condition Boost pressure sensor voltage remains higher than 4.7 V for 3 seconds.
Recoverability
System recovers when boost pressure sensor voltage remains 4.7 V or less for 1
second.
Control effected by electronic control unit
• Control is effected using backup value of 101.3 kPa {1.03 kgf/cm
