Air Flow Meter/Sensor: Testing and Inspection
MASS AIR FLOW (MAF) SENSOR INSPECTION [L3 WITH TC]
Visual Inspection
NOTE:
-
Before performing the following inspection, make sure to follow the procedure as indicated in the troubleshooting flowchart. See: Description and
Operation
1. Visually inspect for the following on the MAF sensor. (See See: Engine, Cooling and Exhaust/Engine/Intake Manifold/Service and Repair.)
-
Damage
-
Cracks
-
Bent terminals
-
Terminal rust
-
If any of the above are found, replace the MAF/IAT sensor.
-
If the monitor item status/specification (reference) is not within the specification even though there is no malfunction, perform the "Circuit
Open/Short Inspection".
Voltage Inspection
1. Remove the MAF/IAT sensor without disconnect 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 voltage at PCM terminal 1AK (M-MDS PID:
MAF) varies.
-
If it cannot be verified even though the related harnesses have no malfunction, replace the MAF/IAT sensor.
