Inspection [10/2014 - ]: Procedure
- INSPECT MASS AIR FLOW METER SUB-ASSEMBLY
- Perform a visual check for any foreign matter on the platinum hot wire (heater) of the mass air flow meter sub-assembly as shown in the illustration.
*a Platinum Hot Wire (Heater) OK
There is no foreign matter.
- Check the intake air temperature sensor (built into the mass air flow meter sub-assembly).
- Measure the resistance according to the value(s) in the table below.
*a Component without harness connected
