Air Temperature Sensor ( Ambient / Intake ): Testing and Inspection
INSPECTION1. Turn Ignition OFF.
2. Remove connector at the Volume Air Flow Meter.
Volume Air Flow Meter Terminal Identification:
3. Using an ohmmeter measure between terminals THA and E2. Resistance should read:
at -20°C (-4°F): 10 - 20 k ohms
at 0°C (32°F): 4 - 7 k ohms
at 20°C (68°F): 2 - 3 k ohms
at 40°C (104°F): 0.9 - 1.3 k ohms
at 60°C (104°F): 0.4 - 0.7 k ohms
4. If reading is out of specification. it will be necessary to replace the Volume Air Flow Meter assembly.
