Hi Scotty! I have a 2007 hyundai accent and I my engine light comes on after a few days when i bought it. The code is P0172B. I hope you could help me on this. Thanks

No. 1-1


A code P0172 may mean that one or more of the following has happened: The MAF (Mass Air Flow) Sensor is dirty or faulty. Note: The use of "oiled" air filters can cause the MAF to become dirty if the filter is over-oiled. There is also an issue with some vehicles where the MAF sensors leak the silicone potting material used to protect the circuitry. There could be a vacuum leak. There could be a fuel pressure or delivery problem
