Product Details

NTK Direct Fit Oxygen Sensor 23020 is part of the NTK Sensor Specialist line, focused on import and domestic coverage with OE application technology. NTK manufactures oxygen sensors using controlled ceramic production and extensive manufacturing tests to help maintain fit, form, and function that align with OE specifications. This sensor is listed for downstream positions on 1996-1999 Chrysler Sebring, 1996-1999 Dodge Avenger, 1996-1999 Mitsubishi Eclipse, and 1997-2000 Mitsubishi Mirage applications.

This part cross-references Bosch 13417 and DENSO Auto Parts 234-4083 for the same application.

Common Issues This Sensor May Address

• Check engine light related to downstream oxygen sensor faults
• Incorrect air-fuel feedback from a worn heated O2 sensor
• Emission test failures tied to sensor response or signal degradation
• Rough idle or drivability concerns caused by inaccurate exhaust oxygen readings
• Replacement needs for a damaged or aging threaded oxygen sensor

Installation Notes and Tips

Verify the vehicle year, make, model, and downstream position before installation. Confirm the 4-wire connector style, 25.0000 harness length, and 18.000 threaded mounting specification match the original sensor. For best results, inspect the exhaust threads and wiring routing before installing the new sensor on Mitsubishi Mirage, Chrysler Sebring, Dodge Avenger, or Mitsubishi Eclipse applications.
