Oxygen Sensors for Dodge Durango (2012-2014) 5.7L Upstream & Downstream

Direct-Fit Oxygen Sensor Replacement Kit for 2012-2014 Dodge Durango

What it Does: The 4-piece oxygen sensor kit monitors pre- and post-catalytic exhaust gas composition on the 2012-2014 Durango to restore closed-loop fuel trim accuracy and resolve emissions-related fault codes.

The Stock Dodge Durango Sensor Degradation

Factory zirconia sensing elements on the WD chassis degrade over time due to thermal cycling, carbon deposition, and exposure to unburned hydrocarbons. As switching frequency slows, the PCM receives delayed voltage feedback, forcing skewed short-term and long-term fuel trims. This thermal fatigue and silica poisoning trigger sluggish engine response, rich-running conditions, fouled spark plugs, reduced catalytic converter efficiency, and persistent check engine lights (P0130-P0161 series).

The Engineering Solution

This 4-piece complete bank replacement kit restores real-time AFR feedback for the 5.7L HEMI V8. Built with double-wall perforated stainless steel protection sleeves, these sensors shield the ceramic planar sensing core from thermal shock and particulate contamination. Pre-terminated factory-match yellow 4-pin inserts in durable black connector shells plug directly into the OEM wiring harness without splicing. High-temp silicone-sleeved wiring harnesses isolate sensitive mV signals from exhaust manifold heat radiant zones, ensuring rapid light-off times and accurate heater circuit continuity.

Frequently Asked Questions

Does this fit the WD Durango?
Yes, this is a direct fit for the 2012-2014 Dodge Durango equipped with the 5.7L HEMI V8 engine.

Do I need to calibrate or tune the PCM after replacing these sensors?
No calibration is necessary, but clearing active diagnostic trouble codes with an OBD-II scanner is required to reset adaptive fuel tables.

The Dodge Powertrain Standard

Maintaining accurate lambda metering protects your catalytic converters from fuel washout while preserving the torque delivery and heavy-duty towing stability demanded of the 5.7L HEMI V8 platform.
