Goss Oxygen Sensor OX479 – OEM-Quality Lambda / O2 Sensor

PRODUCT OVERVIEW

The Goss OX479 oxygen sensor (lambda / O2 sensor) continuously monitors oxygen levels in exhaust gases to enable precise air/fuel ratio control. This helps maintain efficient combustion, stable idle and optimal engine performance.

KEY FEATURES

• Part Number: OX479
• Direct replacement oxygen (O2) / lambda sensor
• Designed to help maintain correct air/fuel ratios
• Supports fuel efficiency and reduced emissions
• Manufactured to OEM-equivalent fit and performance standards

FUNCTION

The oxygen sensor sends feedback to the engine control unit (ECU), allowing it to adjust fuel delivery and ignition parameters. A correctly functioning sensor helps prevent rich or lean mixtures that can cause loss of power, increased fuel consumption or potential engine damage.

WHEN TO REPLACE

• Illuminated check-engine light with O2 sensor fault codes
• Increased fuel consumption or poor emissions test results
• Rough idle, hesitation or loss of power
• Known aged or contaminated sensor

INSTALLATION NOTES

• Always confirm compatibility using the vehicle fitment guide before purchase
• Compare new sensor connector and length to the old unit before installation
• A thread-safe anti-seize compound may be required on the sensor threads (avoid sensor tip)
• Clear any stored fault codes and verify readings after installation
