O2 Oxygen Sensor Upstream Downstream for Dodge Durango (2012-2020) 3.6L

Direct-Fit Upstream & Downstream O2 Sensor Kit for 2012-2020 Dodge Durango (WD)

What it Does: This 4-piece upstream and downstream oxygen sensor kit restores accurate air-fuel ratio feedback and catalyst efficiency monitoring on the 2012-2020 Dodge Durango WD 3.6L Pentastar V6.

The Stock Dodge Durango Sensor Failure

Factory oxygen sensors on the WD chassis with the ERB/ERC 3.6L Pentastar V6 suffer from exhaust thermal fatigue, carbon fouling, and internal heater circuit degradation over time. As the zirconia sensing element ages, voltage switching slows and closed-loop fuel trim accuracy drops. This sluggish response triggers PCM fault codes like P0135, P0155, P0171, and false P0420/P0430 efficiency alerts.

Common Symptoms of a Failing OEM Oxygen Sensor

• Check Engine Light / DTCs: Triggers heater or response faults like P0135, P0155, or P0420/P0430.
• Unstable Fuel Trims: Causes rough idle, sluggish throttle response, and rich or lean mixture skew.
• Emissions Failure: Forces open-loop fueling, reducing fuel economy and failing state emissions inspections.

The Direct-Fit Matched 4-Sensor Solution

Replacing all four sensors simultaneously as a matched upstream and downstream set eliminates bank-to-bank voltage discrepancies on the 3.6L Pentastar V6. Each sensor uses a corrosion-resistant stainless steel shell, laser-welded protective shield, and rapid-heating zirconia element for crisp closed-loop PCM signaling. Factory-style harness connectors ensure direct plug-and-play installation into stock exhaust bungs without splicing wiring.

Frequently Asked Questions & Fitment Warnings

Does this fit the WD Durango?

Yes. Direct fit for the 2012-2020 Dodge Durango 3.6L Pentastar V6 (ERB/ERC). Confirm engine before ordering; 5.7L (except noted 2019 reference) and 6.4L models differ.

Will this clear P0135 or P0420/P0430 codes?

Yes, for sensor faults. New sensors clear heater and response codes like P0135/P0155, while persistent P0420/P0430 indicates catalytic converter wear.

Are connectors ready for plug-and-play installation?

Yes. All four sensors feature OEM-style plugs and pre-threaded bodies for direct exhaust bung installation.
