Product Details

NTK 23014 is a direct fit oxygen sensor for downstream locations on select 1995-1998 Dodge Viper, 1996 Dodge B1500, B2500, B3500, Dakota, Ram 1500, Ram 2500, and Ram 3500, plus 1996 Jeep Cherokee. It also serves downstream right and downstream left positions on 1997-1998 Dodge Viper. This part number 23014 is built for buyers searching for a replacement oxygen sensor that matches OE-style sensor type, connector count, and threaded installation requirements.

This part cross-references Bosch 13138 for the same application.

Common Problems This Sensor Can Address

• Check engine light related to oxygen sensor performance
• Incorrect air-fuel ratio readings from a worn downstream sensor
• Reduced emissions monitoring accuracy
• Slow sensor response from age or contamination
• Failed inspection tied to oxygen sensor fault codes

Installation Notes

Confirm the vehicle position before ordering, since fitment includes downstream right, downstream left, and downstream applications depending on model year. Verify the 4-wire connector, 18 mm thread diameter, and specific-fit configuration against the original sensor before installation. For 1996 Dodge Ram 1500, Ram 2500, and Ram 3500, the fitment notes indicate 1 or 2 sensors may be required depending on the vehicle setup.

Quality Assurance

NTK manufactures oxygen sensors with OE-focused engineering and extensive production testing to support quality and reliability that meets or exceeds original equipment specifications. The Direct Fit Oxygen Sensor line is backed by NTK’s role as a major original equipment oxygen sensor supplier.
