1-S165
(10) Intake Air Temperature Error (DTC P0112 / 172-4, P0113 / 172-3)
P0112 / 172-4: Intake air temperature error: Low
Behaviour during malfunction:
• Amount of white smoke increases at low temperatures
Detection item:
• Ground short circuit of sensor / harness
DTC set preconditions:
• Battery voltage is normal
DTC set parameter:
• Voltage of intake air temperature sensor is 0.05 V or less
Engine warning light:
•ON
Limp home action by engine ECU (system action):
• During start-up = −20 °C (−4 °F) [default value]
• Under other conditions = 40 °C (104 °F) [default value]
Recovery from error:
• Diagnostic counter = zero or Key switch turn OFF

Detection item:
• Open circuit or +B short circuit of sensor / harness
DTC set preconditions:
• Battery voltage is normal
DTC set parameter:
• Voltage of intake air temperature sensor is 4.9 V or above
Engine warning light:
•ON
Limp home action by engine ECU (system action):
