Air Flow and Mass Sensing Devices
Hot film can account for it.
Seems we have hot wire which requires IAT sensor nearby for air temp correction.
Either the PCM performs the correction using the engine IAT sensor or the MAF has an additional sensor and performs internal correction.
cold wire?

wire is maintained at 200* above ambient? Thus always in check?
