MASS AIR FLOW (MAF) SENSOR INSPECTION [Z6]

Note
• Before performing the following inspection, make sure to follow the procedure as indicated in
the troubleshooting flowchart. (See

Visual inspection

1. Visually inspect the MAF sensor for the following:
• Damage, cracks
• Rusted sensor terminal
• Bent sensor terminal
- If there is any malfunction, replace the MAF/IAT sensor. (See
AIR TEMPERATURE (IAT) SENSOR REMOVAL/INSTALLATION

Voltage Inspection

1. Remove the MAF/IAT sensor without disconnecting the MAF/IAT sensor connector.
2. Turn the ignition switch to the ON position.
3. As the air gradually approaches the MAF detection part of the MAF/IAT sensor, verify that the MAF
sensor output voltage (WDS PID: MAF) varies.
• If it cannot be verified even though the related wiring harnesses have no malfunction, replace
the MAF/IAT sensor. (See
SENSOR REMOVAL/INSTALLATION

Circuit Open/Short Inspection

1. Remove the PCM connector cover.
2. Disconnect the PCM connector. (See
