MOTOKU Upstream & Downstream Oxygen Sensor Pair for Chrysler 200 2015–2017 — Direct-Fit, OE-Equivalent

MOTOKU's upstream and downstream oxygen sensor pair replaces worn O2 sensors to restore accurate exhaust oxygen readings for compatible Chrysler, Jeep, Fiat and Ram vehicles.

This MOTOKU oxygen sensor set is engineered to match the fit and function of original equipment sensors for a range of FCA vehicles. If your check-engine light, fuel economy, or emissions testing performance points toward an oxygen sensor issue, this pair is a direct-fit aftermarket replacement designed to simplify repair and get your engine control module receiving correct air/fuel ratio data again.

Which vehicles will these MOTOKU oxygen sensors fit?

These sensors were selected to cover multiple Chrysler, Jeep, Fiat and Ram applications from mid‑2010s models. Always confirm the factory part number and sensor location before ordering to ensure compatibility with your vehicle's engine and exhaust layout.

• Chrysler 200 model years 2015–2017
• Fiat 500X model years 2016–2018
• Jeep Cherokee model years 2014–2019 and Renegade 2015–2020
• Ram ProMaster City model years 2015–2020

How do these upstream and downstream sensors affect performance?

Upstream (pre‑catalyst) sensors monitor the exhaust oxygen content for the engine control module to adjust fuel delivery in real time, while downstream (post‑catalyst) sensors help evaluate converter efficiency. Replacing failing sensors can reduce rough running, improve fuel metering and help clear emission‑related trouble codes when the root cause is the sensor itself.

• Upstream sensor provides immediate air/fuel feedback to the ECU
• Downstream sensor verifies catalytic converter function
• Restores proper fuel trim and can reduce surging or hesitation
• Helps meet emissions inspection requirements when sensors are the issue

What part numbers and OE references does this MOTOKU pair replace?

These MOTOKU oxygen sensors are manufactured to match multiple original equipment references so installation is straightforward and reliable. Use the replaced part numbers to cross‑check your vehicle's required sensor before purchase.

• Replaces common reference numbers: 234-5150, 234-4545, 2344554, 2345151
• Also fits OE references: 5149180AA, 7B0906262B, 68087364AA
• Compatible with additional OE numbers: 68195741AA, 05149180AA

How easy is installation and what should I prepare?

Installation is typically a direct swap using factory mounting points and harness plugs; however, access to the upstream sensor may require lifting the vehicle or removing heat shields. Use proper O2 sensor sockets, anti-seize where appropriate, and verify connector compatibility before securing underbody panels.

• Direct-fit design with factory-style connectors for most listed models
• Recommended tools: O2 sensor socket, ratchet, penetrating oil and torque wrench
• Inspect wiring harness and connector for corrosion before installation
• Clear codes with a scanner after replacement to confirm proper operation

Who is this for: The MOTOKU upstream and downstream oxygen sensor pair is intended for DIY mechanics and professional technicians working on compatible Chrysler, Jeep, Fiat or Ram vehicles from the mid‑2010s. It's suited for anyone replacing faulty O2 sensors to restore proper engine management, improve drivability, or address emissions test failures, provided you verify fit using the listed model years and part numbers.
