Product Details

NTK is part of the NGK family of products and focuses on oxygen sensor coverage for import and domestic vehicles. The brand controls ceramic sensor production from raw material through finished component, which supports consistent sensor construction and application accuracy. NTK 23566 is manufactured and tested to meet or exceed OE specifications, making it a direct replacement choice for vehicles that need the correct sensor response and connector layout.

This part cross-references Bosch 15122 and Mopar 56029085AA for the same application. It is a direct fit oxygen sensor for 2005-2007 Chrysler Pacifica, Town & Country, Dodge Caravan, and Grand Caravan upstream Bank 1 Sensor 1 applications, plus 2007 Jeep Wrangler upstream left and 2008-2009 Dodge Caliber downstream applications.

What This Oxygen Sensor Helps Address

• Check engine light concerns related to oxygen sensor performance
• Incorrect air/fuel ratio readings from a worn upstream sensor
• Slow sensor response affecting fuel control and emissions monitoring
• Fault codes tied to downstream oxygen sensor efficiency
• Replacement needs for damaged wiring or failed heated sensor elements

Installation Notes

Verify the vehicle position before ordering, since this part is used in upstream and downstream locations depending on application. Confirm the connector style, wire count, thread diameter, and harness length against the original sensor before installation. For 2005 Chrysler Pacifica, Town & Country, Dodge Caravan, and Grand Caravan applications, this sensor is listed for Bank 1 Sensor 1. For 2007 Jeep Wrangler, it is listed for upstream left. For 2008-2009 Dodge Caliber, it is listed for downstream.

Quality Assurance

NTK manufactures oxygen sensors with OE application coverage and extensive production testing to support reliable operation and specification match. As a major original equipment oxygen sensor supplier, NTK 23566 is built for consistent performance in the intended Chrysler, Dodge, and Jeep applications.
