Hi all,
My 2014 Ford F-150 5.0L V8 runs on autogas. As a result my catalytic converters don't have to do much work. This results in P0420 and P0430 being thrown: Catalytic converter efficiency below threshold.
After we have determined that the cats are indeed fine we have set P0420 and P0430 to "No error reported". So, on the dash there is no MIL for these errors and on the OBD-II scanner there also is no mention of P0420 and P0430.
But, remote start does not work. The car just honks instead of starts. This is the exact behaviour I get when these two codes are not suppressed.
My question is why does the car refuse to remote start even when these codes (which prevented remote start) are suppressed.
I hope someone can help.
