Generation condition Water temperature sensor voltage remains less than 0.2 V for 3 seconds.
Recoverability
System recovers when water temperature sensor voltage remains 0.2 V or more
for 1 second.
Control effected by electronic control unit
• Control is effected using backup value (at engine startup: –20
°
C; when engine
is running: 80
°
C).
• Exhaust gas recirculation control is stopped.

Generation condition Water temperature sensor voltage remains higher than 4.85 V for 3 seconds.
Recoverability
System recovers when water temperature sensor voltage remains 4.85 V or less
for 1 second.
Control effected by electronic control unit
• Control is effected using backup value (at engine startup: –20 ° C; when engine

Generation condition
The difference in output voltage between accelerator pedal position sensors 1
and 2 remains 70% or more for 6 seconds when the sensors are normal.
Recoverability
System recovers if difference in output voltage between accelerator pedal posi-
tion sensors 1 and 2 remains less than 70% for 3 seconds when the sensors are
normal.
Control effected by electronic control unit – (Low output)

Electronic control unit connector : Accelerator pedal position sensor
Electrical equipment #324: Accelerator pedal position sensor
Electric circuit diagram Accelerator pedal position sensor system
Generation condition Accelerator pedal position sensor 1 voltage remains less than 0.5 V for 1 second.
Recoverability
System recovers when accelerator pedal position sensor 1 voltage remains 0.5 V
or more 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%).
