HINT:

When DTC P007A15 is stored, the ECM enters fail-safe mode. During fail-safe mode, the intake air temperature is estimated to be 45°C (113°F) by the ECM. Fail-safe mode continues until a pass condition is detected.

MONITOR DESCRIPTION

When the ignition switch is turned to ON and the output voltage of the intake air temperature sensor is higher than 4.9 V for 3 seconds or more, the ECM determines that the intake air temperature sensor circuit is malfunctioning and stores a DTC.

CAUTION / NOTICE / HINT

HINT:

Read Freeze Frame Data using the GTS. The ECM records vehicle and driving condition information as Freeze Frame Data the moment a DTC is stored. When troubleshooting, Freeze Frame Data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, if the air fuel ratio was lean or rich, and other data from the time the malfunction occurred.
