higherbro Oxygen O2 Sensor Kit for Chrysler 200 & Dodge Avenger 2.4L — 2PCS Upstream + Downstream, Direct-Fit

higherbro 2PCS Oxygen O2 Sensor kit provides one upstream and one downstream replacement sensor engineered to restore accurate air-fuel feedback for compatible Chrysler, Dodge and Jeep 2.4L engines.

This two-piece sensor set is designed as a direct-fit replacement for specific model years and engines, offering the wiring, connector interface and sensing element needed to integrate with original exhaust monitoring systems. Each sensor is built to match factory fitment dimensions and wiring locations so installation requires minimal modification. The kit helps the vehicle control module receive more reliable exhaust oxygen readings after an original sensor has aged, contaminated, or failed.

Which vehicles and engines will accept this higherbro O2 sensor kit?

This pair fits many Chrysler, Dodge and Jeep applications primarily using 2.4L engines, plus several additional model variations listed by year. Confirm fitment by checking make, model, year and engine at the product page before ordering.

• Chrysler 200 (2011–2014) and many PT Cruiser/Cruiser derivatives with 2.4L engines.
• Dodge Avenger (2011–2014), Caliber, Dart, Neon, Caravan, Journey and Dakota variants as specified.
• Jeep Compass, Liberty, Patriot and Wrangler 2.4L (and select older Wrangler/Ram/Dakota engines where listed).

How do these upstream and downstream sensors differ, and why replace both?

The upstream (front) sensor measures oxygen in exhaust gases before the catalytic converter for fuel trim adjustments; the downstream (rear) sensor monitors converter efficiency afterward. Replacing both ensures consistent readings on both sides of the converter, avoiding mixed signals to the engine control unit and preventing misdiagnosis.

• Upstream sensor: controls fuel mixture by sending fast, responsive signals to the ECU.
• Downstream sensor: verifies catalytic converter performance and emissions control.
• Pair replacement helps reset fuel trim learning and reduces repeated fault codes.

What should I expect during installation and maintenance?

These sensors are supplied to match factory electrical connectors and thread sizes to minimize installation time. Typical installation involves lifting the vehicle, removing the old sensors from the exhaust pipe or manifold, and fitting the new units with proper torque and anti-seize where recommended.

• Tools needed: oxygen sensor socket, ratchet, penetrating lubricant, torque wrench.
• Installation time: usually 30–90 minutes depending on access and corrosion.
• After installation: clear stored fault codes and allow the engine to complete a drive cycle for ECU relearning.

What warranty and pre-purchase checks should I be aware of?

higherbro includes a 1 year unlimited mileage quality guarantee on this sensor pair, and recommends verifying vehicle compatibility using the site’s Select Your Vehicle tool before purchase. Keep original purchase records and note any installation conditions that may affect return eligibility.

• 1 year unlimited mileage quality guarantee for parts defects.
• Confirm make, model, year and engine in the fitment checker before ordering.
• Retain proof of purchase and evidence of installation for warranty claims.

Who is this for: Mechanics, DIY enthusiasts and fleet owners with Chrysler, Dodge or Jeep vehicles that match the listed years and engine types who need a matched upstream and downstream oxygen sensor replacement. This higherbro kit suits anyone seeking factory-style fit and wiring compatibility to restore reliable exhaust oxygen measurement and support emissions and fuel management systems.
