2009 Pontiac G8 aka Karma
I've been getting this code recently and was wondering where to start. I'm assuming it's a O2 sensor or possibly maf? Anyone ever get this code before?
New plugs and intake gaskets two summers ago @ 95K. Did that before I got her tuned.At 105,000 miles may want to consider installing a fresh set of spark plugs and perhaps replace both intake manifold gaskets since they can be compromised while removing. Don't recall reading about the P2190 code very often on the G8 forum.
Looks like that's exactly what the problem was. Muchos gracias...If you supplied the H02 sensors (or a shop got an installed them), its saying that the ECM is detecting a heater malfunction at that position. Short of meter reading to verify that the power an ground wires at that sensor connector are not the cause, it reads like you need to get yet another sensor an replace it again. You could have received 1 of the 2 new units with a faulty internal heater.
