Our 02 Sport van is showing two codes: P0172 Fuel System Rich, P1494
leak Detection Pump Pressure Switch. I think I know what the leak detector switch is but do not know what the other code is. We go thru alot of fuel and I really want to get this fixed can anyone help. Also, are all the engines codes that Dodge uses are they genric from one model to another

There are two O2 sensors. The upstream sensor is mounted forward of the cat on the exhaust manifold right behind the engine. The downstream sensor is mounted either on the cat converter or just aft of it in the exhaust. The fuel filter is mounted on top of the aft end of the fuel tank. The fuel pressure regulator is part of the fuel pump assembly and mounted in the tank.
