Description

DATA TROUBLE CODE: 24

SYSTEM: Intake Air Temperature Sensor Circuit





CIRCUIT DESCRIPTION
The intake air temperature sensor is built into the volume air flow meter and senses the intake air temperature. The structure of the sensor and connection to the engine control module is the same as in the engine coolant temperature sensor.
If the engine control module detects the diagnostic trouble code "24", it operates the fail safe function in which the intake air temperature is assumed to be 20°C (68°F).

DIAGNOSTIC TROUBLE CODE DETECTING CONDITION
- Open or short in intake air temperature sensor Circuit for 0.5 seconds or more.

TROUBLE AREA
- Open or short in intake air temperature sensor circuit.
- Intake air temperature sensor.
- engine control module.

HINT: If diagnostic trouble codes "22" (engine coolant temperature sensor circuit), "24" (intake air temperature sensor circuit) and "41" (throttle position sensor circuit) are output simultaneously, E2 (sensor ground) may be open.
