DTC P0110-11: Intake Air Temperature Sensor 1 Bank 1 Circuit Short to Ground [10/2018 - ]: Description
The intake air temperature sensor, mounted on the mass air flow meter sub-assembly, monitors the intake air temperature. The intake air temperature sensor has a built-in thermistor with a resistance that varies according to the temperature of the intake air. When the intake air temperature is low, the resistance of the thermistor increases. When the temperature is high, the resistance drops. These variations in resistance are transmitted to the ECM as voltage changes.
The intake air temperature detected by the inlet air temperature sensor is converted to a voltage value inside the intake airflow meter assembly, and the voltage value is then output to the ECM. Based on this signal, the ECM increases the fuel injection volume when the engine is cold to improve driveability.
HINT:
When DTC P011011 is stored, the ECM enters fail-safe mode. During fail-safe mode, the intake air temperature is estimated to be 20°C (68°F) by the ECM. Fail-safe mode continues until a pass condition is detected, and the power switch is then turned off.

HINT:
When this DTC is output, check the intake air temperature in the Data List. Enter the following menus: Powertrain / Engine / Data List / Intake Air Temperature.
Refer to DATA LIST / ACTIVE TEST [10/2018 - 08/2021] Refer to DATA LIST / ACTIVE TEST [08/2021 - ]
| DTC No. | Intake Air Temperature | Malfunction |
|---|---|---|
| P011011 | -39°C (-38.2°F) or less |
|
If the Data List value is normal, it may be due to a temporary recovery from the malfunction condition. Check for intermittent problems.
