What This Oxygen Sensor Helps Address

• Check engine light concerns related to oxygen sensor performance
• Incorrect air-fuel mixture readings from a worn sensor
• Emissions test failures tied to sensor response issues
• Rough idle or drivability problems caused by inaccurate exhaust feedback
• Replacement needs on aging Chrysler, Dodge, Plymouth, and Jeep exhaust systems

Installation Notes and Tips

Confirm the sensor position, connector shape, thread size, and overall length against the vehicle application before installation. This part is listed for multiple positions, including front, rear, rear left, front right, and right, so position-specific verification is important on vehicles such as the Dodge Ram 1500 and Jeep Cherokee.

Inspect the harness routing and connector condition before installation, and compare the existing sensor length to the 490.0 specification. Use the included instruction sheet during replacement and verify the application tab for the exact fitment on your vehicle.
