What This Sensor Helps Address

• Check engine light related to oxygen sensor performance
• Incorrect air-fuel mixture feedback to the engine control module
• Reduced emissions system efficiency
• Rough idle or drivability issues tied to exhaust sensor signal loss
• Failed inspection results caused by a worn upstream or downstream sensor

Installation Notes and Tips

Confirm the exact position on your vehicle before ordering, since ES20084 is listed for front left, rear left, and rear right locations depending on application. Verify the connector shape, wire count, and 18 x 1.5 mm thread size against the original sensor before installation. Use the vehicle application data to match California Emission System requirements where noted, and route the harness to avoid exhaust heat and abrasion.
