Vemo V38-76-0021 Oxygen Sensor

VEMO Oxygen Sensor for Nissan and INFINITI

The Vemo V38-76-0021 is a 4-circuit oxygen sensor built for downstream and upstream-left applications across select Nissan and INFINITI models. With a thread pre-greased design, it supports cleaner serviceability and accurate exhaust feedback for emissions control systems.

Compatible With 2002-2018 Nissan Frontier, Pathfinder, Xterra, TITAN, Armada, Sentra, NV1500, NV2500, NV3500, Pathfinder Armada, and 2004-2010 INFINITI QX56 applications. The VEMO line focuses on OE-style replacement parts for emission control and sensor service needs.

Key Features

• Part number: V38-76-0021
• Lambda sensor with thread pre-greased for easier installation prep
• 4-circuit design for signal and heater circuit operation
• Emission control sensor for downstream and upstream-left positions
• Fits a wide range of Nissan Frontier and Nissan TITAN applications
• Also used on select Nissan Pathfinder, Xterra, Armada, Sentra, NV1500, NV2500, NV3500, and INFINITI QX56 models

Product Details

The VEMO V38-76-0021 oxygen sensor is specified for multiple exhaust locations, including downstream, downstream left, downstream right, rear, rear left, upstream, and upstream left positions depending on vehicle application. This broad coverage makes it a practical replacement for Nissan and INFINITI vehicles that rely on precise exhaust oxygen monitoring for fuel control and emissions performance. If you are sourcing a direct-fit oxygen sensor for a Nissan Frontier, Nissan TITAN, or related platform, V38-76-0021 is a relevant OE-style reference to verify against your original part.

This part cross-references Continental 64552 and Delphi ES20172 for the same application.

Common Issues It May Address

• Check engine light related to oxygen sensor performance
• Incorrect air-fuel ratio readings from a worn sensor
• Reduced emissions system efficiency
• Rough idle or drivability concerns tied to exhaust feedback data
• Failed emissions inspection caused by sensor output faults

Installation Notes and Tips

Confirm the exact position, year, and engine application before ordering, since this sensor is listed for multiple downstream and upstream-left locations. The thread pre-greased design helps with removal and installation, but the sensor should still be matched to the original connector, circuit count, and mounting location on the vehicle. For Nissan Frontier, Nissan TITAN, and INFINITI QX56 applications, verify the OE part number and exhaust position against the removed sensor before installation.

Quality Assurance

VEMO parts are positioned as OE-style replacement components for emission control service, with application-specific fitment data used to support accurate part selection. Always confirm the part number V38-76-0021 against the vehicle’s original sensor and service information before installation.
