2000 Dodge Durango 5.2L Running Poorly with P0132, P0135, and P0138 OBD2 Codes After Sensor Replacement

Model: 2000 dodge durango Fault Code: P0132 Posted: 2009-12-26 18:33

I own a 2000 Dodge Durango with a 5.2L engine that has started running poorly after it warms up. The vehicle is now displaying OBD2 fault codes P0132, P0135, and P0138. I've already replaced both the oxygen sensors and reset the ECU codes, but the P0132 code persists. The engine was rebuilt approximately 8,000 miles ago, so it's not a mechanical issue. Despite the sensor replacements, the vehicle runs smoothly when cold but begins to misbehave once warmed up. I'm looking for advice on what else to check next—especially regarding sensor installation or wiring compatibility.

Where did you source your oxygen sensors from? Were they standard universal types or specifically matched parts?

I bought them from AutoZone—started with universal models, then switched to higher-quality ones with proper connectors. Still, the issue persists.

I recommend trying a factory-original oxygen sensor from the dealership. I've seen many new AutoZone sensors fail to clear P0132 codes because they don't meet the correct heater circuit resistance specifications. This is a well-documented issue on several automotive forums.
