Vemo V38-76-0020 Oxygen Sensor

Oxygen Sensor Overview

Vemo V38-76-0020 is a post-catalyst oxygen sensor built for direct replacement applications that use OE number 226A0-ET000. It is specified for a 4-wire, 4-circuit setup with an M18 x 1.5 thread, angular connector, and 450 mm lead length.

Compatible with a wide range of Infiniti and Nissan applications, this sensor is listed for downstream and rear positions across multiple model years. Use V38-76-0020 when replacing a post-catalyst sensor on vehicles such as the Infiniti G37, Infiniti Q70, and Nissan 370Z.

Key Features

• Post-catalyst oxygen sensor for downstream exhaust monitoring
• 4-circuit, 4-pole design for the specified electrical configuration
• Angular connector and black socket color for OE-style routing
• M18 x 1.5 thread size with thread pre-greased for installation prep
• 450 mm lead length for fitment-specific harness reach
• Cross-references Monroe Shocks & Struts 172286 and 182286 for the same application

Detailed Description

Vemo V38-76-0020 is an emission control oxygen sensor intended for post-catalyst use, where it monitors exhaust conditions after the catalytic converter. The sensor’s 4-wire construction, angular connector, and OE-number match to 226A0-ET000 support fitment across many Infiniti and Nissan platforms, including the Infiniti G35, Infiniti FX35, and Nissan Cube. Its compact body dimensions and pre-greased threads help simplify replacement in tight exhaust locations.

This part number, V38-76-0020, is a practical choice for drivers addressing a failed downstream sensor on compatible Infiniti and Nissan vehicles. The application list includes rear and downstream positions, with notes for specific build dates and emissions configurations where applicable.

What It Is Used For

• Replacing a faulty downstream oxygen sensor
• Restoring exhaust feedback after catalyst operation
• Addressing check engine light conditions tied to sensor performance
• Correcting drivability issues caused by inaccurate exhaust readings
• Resolving emissions-related fault codes on supported applications

Installation Notes and Tips

Confirm the OE number 226A0-ET000, connector style, thread size, and lead length before installation. Fitment for V38-76-0020 varies by model year, position, and build date, so verify the exact application on the vehicle before ordering. The sensor is listed for downstream and rear locations, including some left- and right-side applications on select Infiniti models.

Quality Assurance

Vemo V38-76-0020 is cataloged as an aftermarket replacement for the specified OE application and is built to match the listed electrical and mechanical requirements for the supported vehicles.
