234-4881 Heated Oxygen Sensor – Jeep Compass, Patriot & Wrangler | Direct Fit O2 Sensor

Restore Performance, Economy and a Clean Dash

A failing oxygen sensor can trigger a check engine light, increase fuel use, and shorten the life of your catalytic converter. This direct-fit heated oxygen sensor is a replacement for part number 234-4881. It bolts in and plugs in, with no splicing and no modification.

Key Features

• Direct fit: Factory-style connector for plug-and-play installation
• 4-wire heated design: The internal heater brings the sensor to operating temperature quickly for faster closed-loop operation and lower cold-start emissions
• Accurate air/fuel feedback: Helps your ECU keep fuel trims correct and your catalytic converter working efficiently
• Cost-effective repair: A quality aftermarket alternative to dealer-priced sensors
