Question

What is the location of p0430 on a 1996 Mercury Grand Marquis?

Answer 1

Hi there!

P0430 in this case is for one of the catalytic converters on the car. P0430 is for the bank #2 converter. This is the passenger side of the engine on this vehicle.

The converter will need to be replaced. It is the fisrt converter between the front and rear O2 sensors.

Thanks
