Sangyue Oxygen O2 Sensor Kit 2PCS — Upstream & Downstream Direct-Fit for Chrysler/Dodge 2.0–2.4L

The Sangyue 2PCS Oxygen O2 Sensor kit supplies both upstream (bank 1) and downstream (bank 2) sensors as direct-fit replacements designed for many Chrysler, Dodge and Jeep 2.0–2.4L and select older V8 models.

When one or both oxygen sensors fail, engine performance, fuel trim and emissions monitoring can be affected; this Sangyue pair is offered as a matched upstream and downstream set to simplify repair and restore proper sensor feedback for compatible vehicles. Each sensor is built to match OE fitment and wiring locations listed for model years and engines in the fitment table, and the package includes a lifetime of service confidence backed by a one-year unlimited mileage quality guarantee.

How do these Sangyue sensors replace the originals?

These oxygen sensors are made to fit the factory mounting points and connector styles used on the listed Chrysler, Dodge and Jeep vehicles. Installation usually requires removing the faulty sensor, installing the replacement, and reconnecting the vehicle harness—no splicing when the correct model match is selected.

• Direct-fit replacements for upstream and downstream positions
• Compatible with factory wiring connectors on specified models
• No modification or cutting required when matched to vehicle fitment

What vehicles and engines are supported by this 2PCS kit?

This kit covers a broad range of models and years, focusing on 2.0L–2.4L engines and selected older Ram Van V8s indicated in the fitment list. Confirm your vehicle year, engine displacement and bank orientation before ordering to ensure the correct upstream/downstream pairing.

• Chrysler 200 (2011–2014) 2.4L
• Jeep Compass/Liberty/Patriot (2011–2017) 2.0L & 2.4L and older Jeep Wrangler variants
• Dodge models including Journey (2011–2020), Avenger, Caliber, Neon and select Ram Van years

What benefits will I notice after replacing both sensors?

Replacing both upstream and downstream sensors with a matched pair helps reestablish accurate oxygen readings across the exhaust system, which supports the engine control unit’s fuel trim and emissions strategies. While sensors themselves don’t cure unrelated issues, fresh, correctly functioning sensors reduce the likelihood of false fault codes and uneven running caused by aging or contaminated sensors.

• More consistent oxygen readings for better fuel trim control
• Reduced chance of recurring O2-related fault codes
• Matched upstream/downstream pair reduces diagnostic ambiguity

How long do Sangyue O2 sensors last and what warranty is included?

Lifespan varies by driving conditions, fuel quality and exposure to contaminants, but these sensors come with a one-year unlimited mileage quality guarantee to protect against defects. Routine inspection during service intervals will help you identify deterioration, and replacement as a matched set is recommended if both operate outside expected parameters.

• One Year Unlimited Mileage Quality Guarantee included
• Recommended inspection during regular maintenance
• Replace both sensors when diagnosis indicates multi-sensor wear

Who is this for: This Sangyue 2PCS Oxygen O2 Sensor kit is intended for DIY mechanics, independent shops and fleet maintainers who need an affordable, direct-fit upstream and downstream sensor pair for specified Chrysler, Dodge and Jeep vehicles. Verify engine size and model year from the fitment list before purchase to ensure plug-and-play installation; this kit is aimed at owners who want matched sensors to simplify diagnostics and restore proper oxygen-sensing performance.
