MAF Sensor Inspection

NOTE:  Since there is no direct method to test the inspection item, troubleshooting is performed using a known-good component.

Test Procedure 

• Install a known-good MAF sensor/IAT sensor 1 and attempt to reproduce the failure.

Results 

• If the failure is reproduced, there is a problem with other related components.
• If the symptom/DTC goes away, MAF sensor/IAT sensor 1 must be faulty.
