Oxygen Sensors for Ram 1500 (2010-2018) 5.7L Upstream & Downstream

Direct-Fit Oxygen Sensor Set for 2010-2018 Ram 1500 (DS)

What it Does: The Upstream and Downstream Oxygen Sensor Set replaces degraded exhaust gas sensors on the 2010-2018 Ram 1500 to restore precise closed-loop air-fuel management and eliminate diagnostic trouble codes.

The Stock Ram 1500 Sensor Degradation & Exhaust Contamination

Factory zirconia exhaust gas oxygen sensors on the DS chassis endure high thermal cycles and carbon fouling over extended operating hours. Over time, chemical contamination from combustion blow-by and unburned hydrocarbons coats the porous ceramic sensing element, severely dampening response times. A sluggish or drifting sensor misreports the exhaust gas concentration, causing the PCM to introduce erratic short-term and long-term fuel trims. This results in rich or lean running conditions, rough idle, poor fuel economy, and persistent check engine lights including fault codes P0130 through P0161, P0420, and P0430.

The Engineering Solution

This full 4-piece sensor package features fast-acting ceramic thimbles designed for rapid heater circuit light-off, providing precise voltage switching across stoichiometry. Each sensor is encased in high-grade stainless steel with a laser-welded dual-layer protective body that guards against thermal shock and moisture intrusion. Designed with OE-matched lead wire lengths and factory-style 4-pin weather-sealed connectors, these direct-fit units screw seamlessly into existing exhaust bungs with zero wire cutting or repinning, restoring critical closed-loop accuracy.

Frequently Asked Questions & Fitment Warnings

Does this fit the DS 1500?

Yes, this is a direct fit for the 2010-2018 Ram 1500 equipped with the 5.7L HEMI engine. It is not compatible with 3.6L Pentastar V6, 3.7L V6, 4.7L V8, or 3.0L EcoDiesel models.

Do I need to flash the PCM after installation?

No PCM tuning is required, but you must clear stored diagnostic trouble codes and reset the adaptive fuel trim tables with a scan tool after install.

The Ram Heavy-Duty Towing Standard

Maintaining calibrated air-fuel ratios prevents excessive exhaust gas temperatures under sustained grade climbs, protecting your catalytic converters and ensuring maximum pulling torque when towing heavy loads.
