Subaru Legacy Service Manual: Inspection

1. CHECK THE MASS AIR FLOW SENSOR UNIT

1. Connect the battery positive terminal to terminal No. 3 and the battery ground terminal to terminal No. 4, and connect the circuit tester positive terminal to terminal No. 5 and the circuit tester ground terminal to terminal No. 4.

2. Check the voltage changes when air is blown to the mass air flow sensor unit in arrow direction.

2. CHECK THE INTAKE AIR TEMPERATURE SENSOR UNIT

Measure the resistance between intake air temperature sensor terminals.
