P0132 O2 Sensor Fault in 2004 Dodge Ram 1500 with 5.7L Hemi Engine

Model: 2004 Dodge 1500 Fault Code: P0132 Posted: 2013-09-17 17:39

I own a 2004 Dodge Ram 1500 equipped with a 5.7L Hemi engine and am currently experiencing a P0132 diagnostic trouble code, which indicates a high voltage issue with the oxygen sensor in bank 1, sensor 1. When I swapped the pre-catalyst oxygen sensors between bank 1 and bank 2, the code shifted to P0152 (high voltage O2 sensor in bank 2, sensor 1), confirming that one of the sensors is faulty. I replaced the suspected sensor, but the P0132 code has returned. This suggests either a wiring issue, a defective harness, or a deeper problem with the engine's oxygen sensor circuit. Any insights or suggestions on how to diagnose and resolve this issue would be greatly appreciated.
