Common Issues This Sensor Can Address

• Check engine light related to oxygen sensor performance
• Incorrect air-fuel ratio readings from a worn rear sensor
• Slow sensor response after exhaust heat-up
• Emissions test failures tied to faulty downstream sensor data
• Rough fuel control caused by inaccurate exhaust feedback

Installation Notes and Quality

Verify the exact sensor position on your vehicle before ordering, since ES20082 is position-specific for center left, rear left, and rear right locations. Confirm connector shape, wire count, and thread size against the original sensor to ensure proper installation on your Mitsubishi Eclipse, Endeavor, Outlander, Galant, Diamante, Montero Sport, or Montero.
