P0123: Accel Pedal Sensor 1 (warning lamp flashes: 24)
P0182: Fuel Temp Sensor (inlet) Low (warning lamp flashes: 41)
P0183: Fuel Temp Sensor (inlet) High (warning lamp flashes: 41)
P0192: CRS Pressure SNSR (Low) (warning lamp flashes: 11)
Generation condition
Accelerator pedal position sensor 1 voltage remains higher than 4.5 V for 1 sec-
ond.
Recoverability
System recovers when accelerator pedal position sensor 1 voltage remains 4.5 V
or less for 1 second.
Control effected by electronic control unit
• If accelerator pedal position sensor 1 alone is faulty
Control is effected using accelerator pedal position sensor 2.
• 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 Fuel temperature sensor voltage remains higher than 4.8 V for 3 seconds.
Recoverability
System recovers when fuel temperature sensor voltage remains 4.8 V or less for
1 second.

Generation condition Common rail pressure sensor voltage remains less than 0.2 V for 0.25 second.
Recoverability
System recovers (power is re-supplied to electronic control unit) if signal becomes
normal when starter switch is turned OFF (2 minutes or more) → ON.
Control effected by electronic control unit
• Common rail pressure open loop control is effected.
(Output is reduced, and exhaust emissions worsen.)
• Exhaust gas recirculation control is stopped.
• Auto cruise control is stopped.
• Actuator tests “B9: Fuel Leak Check, BB to C0: Injector Test, BA: VGT Test”
are stopped.
