With Manual Transaxle
MASS AIR FLOW SENSOR INSPECTIONUSING THE SST (ENGINE SIGNAL MONITOR)
1. Check the mass air flow sensor for damage and cracks.
SST:
2. Connect the SSTs to the ECM.
3. Measure the voltage at ECM terminal 3B.
4. Verify that the voltage is within the specification.
5. If not as specified, inspect the harness and connector between the mass air flow sensor and the ECM terminal.
6. If there is correct terminal voltage and harness continuity, replace the mass air flow sensor.
USING THE SST (NGS)
1. Check the mass air flow sensor for damage and cracks.
New Generation Star (NGS) Tester Connected To DLC-2:
2. Connect the SSTs to the data link connector-2.
3. Select the "PID/DATA MONITOR AND RECORD" function of the NGS.
4. Select "MAF V" on the NGS display. The NGS measures and shows the voltage.
5. If not as specified, inspect the harness and connector between the mass air flow sensor and the ECM terminal.
6. If there is correct terminal voltage and harness continuity, replace the mass air flow sensor.
NOTE: The scan tool shows the mass airflow rate and load value.
