I received engine codes p0132, p0174, p0175, p2195, p2196, p2197 and p2198

Question

on a 2003 ford expedition, it keeps stalling when coming to a stop and sometimes bucks while driving. codes p0132, p0174, p0175, p2195, p2196, p2197 and p2198

Answer 1

P0132 -02 sensor circuit voltage high (Bank1 sensor 1)

P0174 Fuel trim too lean Bank 2

P0175 Fuel trim too rich Bank 2

P2195 Upstream 02 sensor not switching

P2196 Upstream 02 sensor not switching

P2197 Upstream 02 sensor not switching

P2198 Pstream 02 sensor not switching

Circuit voltage high means the 02 sensor at bank 1 sensor which is a engine management sensor is disconnected, this can be from the harness to the 02 sensor itself,For a fuel trim to go rich and lean this is a vacuum leak which needs to be checked at the fuel pressure regulator or the vacuum hoses that connects to the fuel pressure regulator. For the engine management sensor (upstream sensor) to not switch check and inspect the MAF air tube duct for proper insallation.
