NTK 27005 Air / Fuel Ratio Sensor - Upstream

Overview

NTK 27005 is a direct-fit air/fuel ratio sensor built for specific applications and engineered to match OE-style fit, form, and function. It uses a heated 5-wire design with a 16.5-inch harness for the correct sensor layout on the vehicle.

Fits 2013 Ford Escape, upstream. This NTK 27005 sensor is a focused replacement for the original air/fuel ratio monitoring setup used on that application.

Key Features

• Direct-fit design for specific applications
• Heated 5-wire sensor construction
• 16.5-inch wiring harness length
• 18 mm thread diameter with 0.38 thread length
• Mounting bracket not included

Detailed Description

NTK 27005 is part of NTK’s Direct Fit 5-Wire A/F Sensor line, which is built for applications that require a precise replacement sensor rather than a universal unit. As an air/fuel ratio sensor, it monitors exhaust mixture feedback so the engine management system can maintain proper fuel control and emissions performance. NTK 27005 is a direct replacement for the original sensor on the listed application and is backed by NTK’s OE-focused manufacturing approach. This part cross-references DENSO Auto Parts 234-5039 for the same application.

For 2013 Ford Escape upstream fitment, the NTK 27005 sensor provides the correct heated configuration and connector-style harness length needed for the original installation point. The part number 27005 is also useful when verifying the correct replacement against service information or existing sensor markings.

What It Is Used For

• Replacing a failed air/fuel ratio sensor
• Restoring accurate exhaust mixture feedback
• Addressing check engine light concerns tied to sensor faults
• Correcting drivability issues caused by inaccurate fuel control data
• Maintaining emissions system performance on the listed application

Installation Notes and Tips

Confirm the upstream location and sensor connector style before installation. Verify thread size and harness length against the original part to ensure proper routing and fit. The part number 27005 should be matched to the vehicle application and service data before replacement.
