    Try the Seville forum. You'll likely find more feedback applicable to that car. The 2005 & up (here) is quite different.

    Well after scanning it with a Launch x431, we tried to get the reading for a MAF. 0Hz 0G/s. We went and checked a Sonoma of the same year and the MAF gave us a reading (forget the numbers but it read). The MAF on the Caddy has power and a good ground but still not reading. The boss also tried a new MAF and nothing changed.
