Sangyue Oxygen Sensor Set for Chrysler/Dodge 2005–2010 3.3L/3.8L — Upstream & Downstream OE-Fit 2-Piece

Sangyue replacement oxygen sensors — a matched upstream and downstream set designed to restore accurate air-fuel monitoring for compatible Chrysler and Dodge V6 engines.

These Sangyue oxygen sensors are sold as a pair (one upstream, one downstream) engineered to fit specific Chrysler Town & Country, Dodge Grand Caravan and Chrysler Pacifica model years and engine sizes. They supply the signals your engine computer uses to adjust fuel delivery and emissions control. Each sensor is manufactured to match OE fitment and wiring, simplifying swap-in replacement for vehicles listed below. Before ordering, confirm your exact vehicle year, engine displacement and original sensor position using the "Select Your Vehicle" option on the product page to ensure correct compatibility.

Which vehicles and engines are these sensors compatible with?

These sensors are built for several Chrysler and Dodge models with 3.3L or 3.8L V6 engines across mid-2000s model years. Compatibility focuses on head and exhaust positions that vary by model and year.

• Chrysler Town & Country: 2006–2010, 3.3L and 3.8L engines
• Dodge Grand Caravan: 2006–2010, 3.3L and 3.8L engines
• Chrysler Pacifica: 2005–2008, 3.8L engine
• Caravan (listed as Caravan): 2005–2007, 3.3L engine

How are the upstream and downstream sensors supplied and installed?

The product ships with one upstream sensor and one downstream sensor so you can replace both critical monitoring points at once. Each sensor includes the connector and pigtail compatible with the OEM harness on the listed vehicles.

• Packaged as a 2-piece set: 1 upstream + 1 downstream
• Direct-fit connectors to match factory wiring harnesses
• Torque and installation follow standard oxygen sensor procedures — anti-seize may be pre-applied or provided

What benefits should I expect after replacing failing oxygen sensors?

Fresh upstream and downstream sensors help the engine control module receive accurate exhaust composition data for better fuel trims and emissions regulation. Replacing both sensors at once reduces diagnostic ambiguity and helps prevent recurring fault codes.

• Restores reliable O2 voltage and heater circuit responses
• Helps clear or prevent check engine light codes related to O2 sensors
• Improves engine management accuracy during warm-up and steady-state operation

Is there a warranty or guarantee with these Sangyue sensors?

Yes — the sensors come with a one-year unlimited mileage quality guarantee that covers manufacturing defects under normal use. Keep your purchase information and proof of installation for warranty claims or returns.

• One Year Unlimited Mileage Quality Guarantee included
• Warranty covers defects but not damage from improper installation or abuse
• Contact seller with vehicle details and purchase proof for support

Who is this for: These Sangyue upstream and downstream oxygen sensors are aimed at DIY mechanics, independent shops and fleet owners who maintain mid-2000s Chrysler and Dodge V6 vehicles (3.3L or 3.8L). If your vehicle matches the listed model years and engine sizes and you need a direct-fit replacement with a backed quality guarantee, this paired sensor set provides a practical, cost-effective option. Always verify fitment with your vehicle selector before purchasing to ensure correct sensor location and connector compatibility.
