NTK 22136 Oxygen Sensor - Upstream

Direct Fit Oxygen Sensor for Ford and Mercury

NTK 22136 is a direct fit heated oxygen sensor built for specific upstream applications on select Ford and Mercury vehicles. It is engineered for Bank 1 Sensor 1 placement and uses a threaded mounting design with a 4-wire harness for OE-style replacement.

Compatible with 2011-2012 Ford Escape upstream, 2011-2012 Ford Fusion upstream, and 2011 Mercury Milan upstream, this NTK oxygen sensor supports accurate exhaust feedback for the engine management system. The NTK Direct Fit Oxygen Sensor line focuses on application-specific fit, form, and function for import and domestic coverage.

Key Features

• Part number 22136 direct fit oxygen sensor
• Heated sensor design for faster operating response
• Specific fit for targeted OE replacement applications
• 4-wire configuration with 15.0000-inch wiring harness length
• 18.000 thread diameter and threaded mounting type
• Bank 1 Sensor 1 upstream placement

Application Details

Fits 2011-2012 Ford Escape, upstream. Fits 2011-2012 Ford Fusion, upstream. Fits 2011 Mercury Milan, upstream. This part cross-references DENSO Auto Parts 234-4740 for the same application.

NTK is a major original equipment oxygen sensor manufacturer, and this part reflects that OE-focused approach. The sensor is manufactured with ceramic technology control from raw material through finished product, then tested during production to help meet or exceed OE specifications for fit and performance. If you are replacing a failing upstream oxygen sensor on a Ford Escape, Ford Fusion, or Mercury Milan, NTK 22136 provides a direct replacement path.

What This Sensor Helps Address

• Check engine light related to upstream oxygen sensor faults
• Incorrect air-fuel ratio feedback to the engine control module
• Rough idle or drivability issues tied to sensor signal errors
• Emissions test failures caused by a worn oxygen sensor
• Slow sensor response from an aging heated O2 sensor

Installation Notes and Tips

Confirm Bank 1 Sensor 1 location before installation and verify connector style, thread size, and harness routing against the original sensor. Because this is a specific-fit threaded oxygen sensor, proper exhaust thread condition and secure electrical connection are important for reliable operation. Use the vehicle service information for torque and diagnostic reset procedures.

Quality Assurance

NTK manufactures oxygen sensors to OE-level application standards and tests them during production for quality and reliability. The Direct Fit Oxygen Sensor line is built to support accurate replacement on import and domestic vehicles, including Ford Escape, Ford Fusion, and Mercury Milan applications.
