Hella 7.05271.69.0 Oxygen Sensor - Downstream, Downstream Left or Downstream Right

Oxygen Sensor for Nissan and INFINITI

This Hella oxygen sensor, part number 7.05271.69.0, is a downstream replacement for select Nissan and INFINITI applications. It supports accurate exhaust monitoring for vehicles such as the Nissan Murano, Nissan Maxima, and INFINITI FX35 when the OE reference matches the listed fitment.

Brand Line: Pierburg distributed by Hella identifies this sensor as part of a Pierburg product line supplied through Hella distribution, giving buyers a direct OE-reference option for specific downstream positions.

• Downstream oxygen sensor for monitored exhaust feedback after the catalytic converter
• Fits select Nissan and INFINITI models with OE No. 226A1AM601, 226A1AR210, or 226A18U700 as listed
• Application-specific fitment for downstream left, downstream right, and downstream positions
• Hella part number 7.05271.69.0 for catalog and cross-check use
• Compatible with multiple 2002-2010 Nissan and INFINITI platforms

Detailed Fitment and Application

Compatible With 2006-2010 INFINITI M45, downstream left; 2004-2009 Nissan Quest, downstream left; 2003-2008 INFINITI FX45, downstream left; 2007-2008 Nissan Maxima, downstream; 2003-2007 Nissan Murano, downstream; 2003-2006 INFINITI FX35, downstream left; 2003-2006 INFINITI G35, downstream left; 2006 INFINITI M35, downstream left; 2002-2006 INFINITI Q45, downstream left; 2003-2006 Nissan 350Z, downstream left; 2004-2006 Nissan Altima, downstream right or downstream; 2004-2006 Nissan Maxima, downstream left; 2003-2006 Nissan Sentra, downstream; and 2003-2004 INFINITI M45, downstream left.

What This Sensor Helps Address

• Check engine light related to downstream oxygen sensor performance
• Incorrect exhaust oxygen readings after the catalytic converter
• Emissions inspection failures tied to sensor faults
• Rough fuel control caused by inaccurate exhaust feedback
• Diagnostic trouble codes associated with the listed downstream sensor positions

Installation Notes

Verify the OE number and sensor position before ordering, since this part is listed for downstream left, downstream right, and downstream locations depending on vehicle. Match the connector and routing to the original sensor on the specific Nissan or INFINITI model, and confirm the application against the vehicle identification data before installation.
