Tests DA: Intake Air Temperature (IAT) Sensor
PINPOINT TEST DA: INTAKE AIR TEMPERATURE (IAT) SENSOR
This pinpoint test is intended to diagnose the following:
^ integrated mass air flow/intake air temperature ( MAF/IAT) sensor (12B579)
^ harness circuits: IAT and SIGRTN
^ powertrain control module (PCM) (12A650)
Voltage values calculated for VREF equal 5 volts. These values can vary by 15% due to sensor and VREF variations
