I searched and they only fix I can find out about it was for the eco-boost fuel pressure sensor. Does this apply to the gt as well? My car cuts off sometimes when coming to a stop
P0148 can be:
- Severely restricted fuel filter (if applicable)
- Severely restricted fuel supply line
- Damaged or worn fuel pump
- Damaged or contaminated mass air flow (MAF) sensor
Try cleaning your MAF and also make sure that the harnesses to the MAF as well as the connectors are not damaged and are secure.
Also to note:
There was an older thread on this site discussing fuel delivery and that code and the M6G member who had posted about it found out later that the problem was related to a failing fuel pump.
