NTK 23070 Oxygen Sensor

Direct Fit Oxygen Sensor for Jeep and Dodge

NTK 23070 is a direct fit heated oxygen sensor built for specific applications on select Dodge Durango, Jeep Grand Cherokee, and Jeep Wrangler models. It uses a threaded mounting design, 4-wire configuration, and 10-inch wiring harness length for OE-style replacement on upstream and downstream positions.

Key Features

• Direct fit oxygen sensor for specific vehicle applications
• Heated sensor design for faster operating response
• 4-wire construction for proper signal and heater circuit function
• Threaded mounting type with 18 mm thread diameter
• 10-inch wiring harness length for application-specific routing
• Built to meet or exceed OE specifications through manufacturing testing

Product Details

NTK 23070 is part of the NTK Direct Fit Oxygen Sensor line, a product line focused on OE-style replacement coverage for import and domestic vehicles. NTK uses ceramic-based sensor technology and controlled manufacturing processes to maintain fit, form, and function across its oxygen sensor range. This part cross-references Bosch 18125 for the same application. It is listed for 2011 Dodge Durango, 2011 Jeep Grand Cherokee, and 2011 Jeep Wrangler applications, including upstream right, upstream left, downstream right, and downstream left positions where specified. For buyers searching for a 2011 Jeep Grand Cherokee upstream oxygen sensor or a 2011 Dodge Durango downstream oxygen sensor, NTK 23070 provides a direct replacement option.

Common Issues This Sensor Can Address

• Check engine light related to oxygen sensor circuit faults
• Incorrect air-fuel ratio readings from a worn sensor
• Slow sensor response during closed-loop fuel control
• Heater circuit trouble codes tied to a failing heated sensor
• Emissions test failures caused by degraded oxygen sensor performance

Installation Notes and Tips

Confirm the exact position before ordering, since this part is listed for both upstream and downstream locations on select vehicles. Match the connector, thread size, and harness routing to the original sensor before installation. For best results, inspect the exhaust threads and wiring path for damage, corrosion, or heat wear before fitting the replacement sensor. Search terms such as 2011 Dodge Durango upstream oxygen sensor, 2011 Jeep Grand Cherokee downstream oxygen sensor, and 2010-2011 Jeep Wrangler oxygen sensor all point to the same type of application-specific replacement coverage.

Quality Assurance

NTK is a major original equipment oxygen sensor manufacturer, and its sensors are extensively tested during production to help ensure reliable operation and OE-level specification compliance. NTK 23070 reflects that OE-focused approach for select Dodge and Jeep applications, including the 2011 Dodge Durango and 2011 Jeep Grand Cherokee.
