MX-5 Miata Mazdaspeed L4-1.8L DOHC Turbo (2004)
Intake Air Temperature Sensor: Testing and Inspection
INTAKE AIR TEMPERATURE (IAT) SENSOR INSPECTION
Inspection of Resistance
NOTE: Perform the following test only when directed.
1. Disconnect the IAT sensor connector.
2. Remove the IAT sensor.
3. Place the IAT sensor in water with a thermometer, and heat the water gradually.
4. Measure the resistance of the IAT sensor using an ohmmeter.
-
If IAT sensor is okay, but PID value is out of specification, perform the "Circuit Open/Short Inspection".
-
If not as specified, replace the IAT sensor.
5. Reconnect the IAT sensor connector.
