The Mass Air Flow sensor measures the mass of air entering an engine.\u00a0 The fuel injection uses this and other information to predict the correct fuel\/air mixture.\u00a0 The MAF sensor used on the Cadillac STS-V and several other GM vehicles is the ACDelco 213-4222, GM p\/n 15865791.<\/p>\n

\"Looking<\/a>

Looking up the intake tube at the MAF<\/p><\/div>\n

This sensor is actually made by Hitachi<\/a>.\u00a0 It is a combined sensor, and measures the mass air flow as well as the temperature of the air passing through the sensor.<\/p>\n

The Camaro Communit<\/a>y has discovered that not all examples of the same part number have identical responsive properties.\u00a0 Summary<\/a>.<\/p>\n

This MAF is a card type MAF, which allows use of the same low-restrictive flow MAF sensor in a variety of intake diameter systems.\u00a0 The Camaro and the STS-V for example use the same sensor.<\/p>\n

What the hu-bub is about is that some lots of the sensor are –while working correctly — less responsive, and some lots are more responsive.\u00a0 Although the part numbers are the same, the more responsive examples have a letter-number lot code along the side of the device, as opposed to a single-letter designator for the less responsive examples.<\/p>\n

My STS-V MAF sensor is a “D” model, so I have ordered a cherry-picked letter-number model from Apex Motorsports<\/a> to replace the current one.\u00a0 I hope to swap to the more responsive MAF next trip to the dyno.<\/p>\n
