NTK 27036 Air / Fuel Ratio Sensor - Upstream

Overview

NTK 27036 is a direct-fit air/fuel ratio sensor built for specific applications and engineered for accurate exhaust feedback. It uses a heated, 5-wire design and is made to match OE fit, form, and function for service replacement work.

Compatible with 2014-2017 Fiat 500L, upstream. This NTK 27036 sensor is a focused replacement for import applications that require precise air/fuel monitoring.

Key Features

• Direct-fit air/fuel ratio sensor for specific applications
• Heated sensor design for faster operating readiness
• 5-wire configuration for the correct signal setup
• 18.000 mm thread diameter with 0.38 thread length
• 23.62 wiring harness length for application-specific routing
• NTK OE-style engineering backed by extensive manufacturing testing

Detailed Description

NTK 27036 is part of the Direct Fit 5-Wire A/F Sensor line and is engineered for vehicles that require a specific upstream air/fuel ratio sensor. For 2014-2017 Fiat 500L applications, it provides the correct sensor architecture for maintaining accurate exhaust monitoring and engine management feedback. The heated design helps the sensor reach operating temperature efficiently, while the 5-wire layout supports the intended signal configuration. NTK 27036 is built with OE-level fit, form, and function in mind, and the part is extensively tested during manufacturing to meet or exceed original equipment specifications. This part cross-references FCA (e.g., 68201261AA) for the same application.

What It Is Used For

• Replacing a worn or slow-responding air/fuel ratio sensor
• Restoring accurate exhaust mixture feedback to the engine control system
• Addressing sensor-related fault codes tied to upstream monitoring
• Correcting drivability issues caused by inaccurate air/fuel data
• Maintaining proper emissions system operation on the Fiat 500L

Installation Notes and Tips

Verify the vehicle application, upstream location, and connector/wire count before installation. Match the thread diameter and thread length to the original sensor specification, and inspect the harness routing path so the 23.62-length lead is positioned without strain. Use the part number 27036 to confirm the correct replacement before service.

Quality Assurance

NTK is part of the NGK family of products and is recognized for OE oxygen sensor manufacturing. The 27036 sensor is extensively tested during production to help ensure quality and reliability that meet or exceed OE specifications.
