Mass Air Flow Meter: Inspection
- INSPECT MASS AIR FLOW METER
- Visually check for any foreign matter on the platinum hot wire (heater) of the mass air flow meter.
OK: There is no foreign matter.
If the result is not as specified, replace the mass air flow meter.
- Measure the resistance according to the value (s) in the table below.
