NTK 23522 Oxygen Sensor

Direct Fit Oxygen Sensor for Mitsubishi and Chrysler

NTK 23522 is a heated direct fit oxygen sensor built for specific downstream applications on Mitsubishi, Chrysler, and Dodge vehicles. It is designed to match original equipment fit, form, and function for service replacement on models such as the Mitsubishi Eclipse, Galant, and Montero.

Key Features

• Heated oxygen sensor with a specific-fit design
• Direct fit replacement for threaded mounting applications
• 4-wire configuration with a 28.5-inch wiring harness
• 18 mm thread diameter for OE-style installation
• Built for downstream rear, downstream right, downstream left, downstream front, and downstream positions where listed
• NTK part number 23522 for catalog and service identification

Product Details

NTK Direct Fit Oxygen Sensor 23522 is part of the NTK Sensor Specialist line, developed for import and domestic emission control service. NTK uses ceramic manufacturing expertise and OE-focused engineering to control sensor materials from raw input through finished product. The result is an oxygen sensor platform that is manufactured and tested to meet or exceed OE specifications for fit and reliability. This part cross-references Bosch 13412 and DENSO Auto Parts 234-4656 for the same application.

Compatible With 2001-2012 Mitsubishi Eclipse, downstream rear; 2004-2009 Mitsubishi Galant, downstream rear; 2001-2006 Mitsubishi Montero, downstream right; 2001-2005 Chrysler Sebring, downstream right or downstream left; 2001-2005 Dodge Stratus, downstream right or downstream left; and additional downstream applications listed for Mitsubishi Galant, Eclipse, and Montero. Use NTK 23522 when replacing an OE-style heated oxygen sensor on these vehicles.

Common Issues This Sensor Can Address

• Check engine light related to oxygen sensor performance
• Fault codes tied to downstream sensor response or signal output
• Incorrect air-fuel feedback from a worn heated oxygen sensor
• Emissions test failures caused by a degraded sensor
• Rough fuel control from an aging OE-style sensor

Installation Notes and Tips

Verify the vehicle year, engine/emissions configuration, and sensor position before ordering. This sensor uses a threaded mounting type and a 4-wire heated design, so connector routing and harness length should be checked against the original part. For best results, compare the removed sensor to NTK 23522 before installation on Mitsubishi Eclipse, Galant, Montero, Chrysler Sebring, or Dodge Stratus applications.

Quality Assurance

NTK is a major original equipment oxygen sensor manufacturer with extensive manufacturing test procedures in place to support OE-level fit and reliability. The brand’s direct fit oxygen sensor line is engineered for service replacement across import and domestic emission control applications.
