Intake Air Temperature (IAT) Sensor Circuit Low Voltage

Description

If the IAT sensor output voltage is excessively low, the Powertrain Control Module (PCM) detects a malfunction and a DTC is stored. The execution time is continuous and the duration time is 2 seconds or more. The IAT sensor output voltage is 0.08 V or less for at least 2 seconds. NOTE: Before you troubleshoot, record all freeze data and any on-board snapshot.
