(9) Intake Air Temperature Error (DTC P0112 / 172-4, P0113 / 172-3)

P0112 / 172-4: Intake air temperature error (Low side)
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
System action:
