NewYall Oxygen O2 Sensor Pack of 4 for Chrysler Dodge Jeep — Upstream/Downstream Replacement, Direct-Fit

NewYall Pack of 4 oxygen sensors (upstream and downstream identical) restores accurate air–fuel readings for compatible Chrysler, Dodge, and Jeep vehicles.

These NewYall oxygen (O2) sensors are sold as a set of four and designed to replace both upstream and downstream sensors when the same part fits each bank. They measure exhaust oxygen content so the engine control unit can adjust fuel delivery. Before ordering, verify vehicle compatibility using the included fitment list; if your application requires different upstream and downstream sensors, this kit is not appropriate.

Which vehicles are these NewYall O2 sensors compatible with?

These sensors are made to match a variety of Chrysler, Dodge, and Jeep models across multiple years. Compatibility depends on the engine and production year; check your vehicle model year against the fitment list to ensure a correct match.

• Chrysler models: 300M, Pacifica, PT Cruiser, Sebring, Town & Country, Aspen, 300, 200 (specific years listed).
• Dodge models: Intrepid, Dakota, Neon, Stratus, Viper, Durango, Grand Caravan, Magnum, Ram series, Nitro, Caliber, Charger, Avenger, Challenger, Journey.
• Jeep models: Commander, Grand Cherokee, Liberty, Wrangler, Compass, Patriot (specific years listed).

How do I know if I need these upstream and downstream sensors?

If your vehicle reports O2 sensor faults, rough idle, elevated emissions, or poor fuel economy, the oxygen sensors may be degraded. Use an OBD-II scanner to confirm fault codes refer to O2 sensors and compare your sensor part number or fitment to this product listing.

• Run a diagnostics scan for codes P0130–P0167 (common O2 sensor codes).
• Compare the physical connector and thread size to your current sensors.
• Confirm make, model, and year in the fitment table before purchasing.

What should I expect during installation and performance?

Installation is straightforward for mechanically experienced DIYers or a trusted mechanic; sensors thread into the exhaust system and connect to the factory wiring harness. After installation, the ECU may need a few drive cycles to adapt to the new sensor readings and clear stored codes.

• Hand-tighten then torque to manufacturer spec to prevent leaks and sensor damage.
• Use anti-seize only if specified and avoid contaminating the sensing tip.
• Allow several drive cycles for the ECU to relearn and stabilize fuel trims.

Are there important purchase precautions I should know?

Yes — this listing includes identical upstream and downstream sensors. If your vehicle requires different upstream vs downstream part numbers, do not buy this pack. Fitment verification is essential to avoid returns and ensure correct operation.

• ATTENTION: Upstream sensor is the SAME as the downstream sensor; do NOT order if different sensors are required.
• Confirm vehicle compatibility using the model-year fitment table provided.
• Contact support with your VIN if you need help confirming fitment.

Who is this for: This NewYall pack of four O2 sensors is aimed at owners and mechanics of Chrysler, Dodge, and Jeep vehicles listed in the fitment table who need to replace multiple identical sensors at once. It suits customers seeking a complete set for ease of installation or those replacing sensors on both engine banks, provided the identical sensor specification matches their vehicle. If your application calls for different upstream and downstream sensors, choose a part number set that specifies each sensor separately.
