What This Sensor Helps Address

• Check engine light related to oxygen sensor performance
• Incorrect air-fuel ratio readings from a worn upstream or downstream sensor
• Rough idle, hesitation, or drivability issues tied to exhaust feedback
• Reduced fuel economy caused by inaccurate exhaust oxygen data
• Emission test failures linked to sensor response problems

Installation Notes

Confirm the exact position on your vehicle before ordering, since ES20081 is used in multiple locations such as front left, rear right, rear left, center, and front. Match the connector shape, wire count, and thread size to the original sensor, and verify California Emission System notes where listed. For Mitsubishi Montero, Montero Sport, and Diamante applications, position and emissions configuration are critical for correct fitment.
