What This Oxygen Sensor Helps Address

• Check engine light concerns related to oxygen sensor performance
• Incorrect air-fuel ratio readings
• Rough idle or drivability issues tied to exhaust feedback
• Failed emissions testing caused by a worn sensor
• Slow sensor response on heated oxygen sensor circuits

Installation Notes and Tips

Verify the exact position on your vehicle before ordering, since this part is listed for front, front left, front right, and rear locations depending on application. Match the connector shape, wire count, and thread size to the original sensor, and confirm California Emission System coverage where noted in the fitment list. For Mitsubishi Eclipse, Galant, Mirage, and Endeavor applications, position and emissions configuration are critical for correct selection.

Quality Assurance

Delphi builds aftermarket parts using OE experience and engineering knowledge developed through long-term supply relationships with major automakers. That OE background is reflected in the ES20148 oxygen sensor’s application-specific design and fitment-focused construction.
