Intake Air Temperature Circuit Malfunction

FAULT ID
P0110

TITLE
Intake Air Temperature Circuit Malfunction

BACKGROUND
- The intake air temperature sensor converts the intake air temperature to a voltage and outputs it.
- The engine control module checks whether the voltage is within a specified range.

RANGE OF CHECK
- Ignition switch: ON
- Excluding 60 seconds after the ignition switch is turned to ON or immediately after the engine starts.

SET CONDITIONS
- Sensor output voltage is 4.6 V or more (corresponding to an intake air temperature of -45°C (-49°F) or less) for 4 seconds.

or

- Sensor output voltage is 0.2 V or less (corresponding to an intake air temperature of 125°C (257°F) or more) for 4 seconds.

EFFECT
Limp-in
- Controls as if the intake air temperature is 25°C (77° F).

PROBABLE CAUSES
- Intake air temperature sensor failed.
- Open or shorted the intake air temperature sensor circuit, or loose connector.
- Engine control module failed.
