Air Flow Meter/Sensor: Testing and Inspection
MASS AIR FLOW SENSOR (MAF SENSOR)
Inspection
NOTE: Use voltmeter with high-impedance (10 kOhms/V minimum) or digital type voltmeter.
1) Remove ECM (PCM) with bracket, relays, fuse box and wire harness previously outlined.
2) Connect couplers to ECM (PCM).
3) Connect voltmeter to "B+" terminal of MAF sensor coupler disconnected and ground.
4) Turn ignition switch ON and check that voltage is battery voltage.
If not, check if wire harness is open or connection is poor.
5) Turn ignition switch OFF and connect MAF sensor coupler to MAF sensor.
6) Turn ignition switch ON and check voltage at "E32-9" (E175-9) terminal.
Voltage: 1.0 - 1.6 V
