• OE-style replacement for Chrysler Sebring and Dodge Stratus
• NTK part number 23146

Product Details

NTK Direct Fit Oxygen Sensor 23146 is engineered for import and domestic emission control applications, with manufacturing control over the ceramic sensing element from raw material through finished sensor. As part of NTK’s direct fit oxygen sensor line, this unit is built for superior fit, form, and function and is tested during production to meet or exceed OE specifications. It is a direct replacement choice for 2003-2004 Chrysler Sebring upstream Bank 1 Sensor 1 service and 2003-2004 Dodge Stratus upstream Bank 1 Sensor 1 service. This part cross-references Bosch 15299 and DENSO Auto Parts 234-4596 for the same application.

Common Issues This Sensor Can Address

• Check engine light related to upstream oxygen sensor performance
• Incorrect air-fuel ratio readings from a worn sensor
• Slow sensor response affecting fuel control
• Emissions test failure caused by a faulty Bank 1 Sensor 1 unit
• Rough idle or drivability concerns tied to oxygen sensor degradation

Installation Notes and Tips

• Fits 2004 Chrysler Sebring, Upstream; B1S1; w/o Next Gen. Eng. Controller; 16.75" pigtail; black connector
• Fits 2004 Dodge Stratus, Upstream; B1S1; w/o Next Gen. Eng. Controller; 16.75" pigtail; black connector
