With Automatic Transaxle
INSPECTIONUsing the Special Service Tool (SST) (104 Pin Breakout Box)
1. Check the mass air flow sensor for damage and cracks.
2. Connect the SST to the Powertrain Control Module (PCM).
3. Measure the voltage at PCM terminal 88.
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 PGM 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 New Generation Star (NGS) tester.
4. Select the mass air flow sensor on the NGS. 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 PCM 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.
