3. Turn ignition switch ON.
4. Check the voltage between mass air flow sensor harness connector and ground.
Is the inspection result normal? YES >> GO TO 4.
NO >> GO TO 3.
3.DETECT MALFUNCTIONING PART
Check the following.
• Harness connectors E8, F1 • Harness for open or short between IPDM E/R and mass air flow sensor
>> Repair open circuit or short to ground or short to power in harness or connectors.
4.CHECK MASS AIR FLOW SENSOR GROUND CIRCUIT FOR OPEN AND SHORT
1. Turn ignition switch OFF.
2. Disconnect ECM harness connectors.
3. Check the continuity between mass air flow sensor harness connector and ECM harness connector.
4. Also check harness for short to ground and short to power.
Is the inspection result normal? YES >> GO TO 5.
NO >> Repair open circuit or short to ground or short to power in harness or connectors.
5.CHECK MASS AIR FLOW SENSOR NPUT SIGNAL CIRCUIT FOR OPEN AND SHORT
1. Check the continuity between mass air flow sensor harness connector and ECM harness connector.
2. Also check harness for short to ground and short to power.
Is the inspection result normal? YES >> GO TO 6.
NO >> Repair open circuit or short to ground or short to power in harness or connectors.
6.CHECK MASS AIR FLOW SENSOR
Refer to EC-902, "Component Inspection".

COMPONENT PARTS
Circuit Breaker
The PTC thermistor generates heat in response to current flow. The
temperature (and resistance) of the thermistor element varies with
current flow. Excessive current flow will cause the element's temperature
to rise. When the temperature reaches a specified level ...
