P0112: INT Air Temp. SNSR (Low) (warning lamp flashes: 44)
P0113: INT Air Temp. SNSR (High) (warning lamp flashes: 44)
P0116: Water Temp SNSR (Plausibility) (warning lamp flashes: 21)

Generation condition
Intake air temperature sensor 1 voltage is at or below the specified value
(0.15 V).
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
• Backup value (25°C) is used.
• 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 1
• Malfunction of each connector
• Malfunction of intake air temperature sensor 1
• Malfunction of engine electronic control unit
Generation condition
Intake air temperature sensor 1 voltage is at or above the specified value
(4.87 V).
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
• Backup value (25°C) is used.
• 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 1
• Malfunction of each connector
• Malfunction of intake air temperature sensor 1
• Malfunction of engine electronic control unit
Generation condition
Engine electronic control unit has judged water temperature sensor abnormal as
a result of comparison with conditions of other sensors.
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
• Backup value (80°C) is used.
• 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 water temperature sensor
• Malfunction of each connector
• Malfunction of water temperature sensor
• Malfunction of engine electronic control unit
Generation condition Water temperature sensor voltage is at or below the specified value (0.2 V).
