Goss OX672 Oxygen Sensor – OEM-Style Lambda Sensor Replacement

PRODUCT OVERVIEW

The Goss OX672 oxygen sensor (lambda sensor) accurately measures oxygen content in exhaust gases to enable precise air/fuel ratio control for engine efficiency, performance and emissions control.

KEY FEATURES

• Direct replacement O2 sensor for worn or failed units
• Helps maintain correct air/fuel ratios for performance and fuel economy
• Supports reduced emissions and smoother engine operation
• OEM-style design for straightforward installation

FUNCTION

This oxygen sensor continuously monitors the oxygen level in the exhaust stream and sends feedback to the engine control unit (ECU). The ECU uses this data to adjust fuelling and help prevent rich or lean running conditions that can cause poor fuel economy, loss of power and increased emissions.

WHEN TO REPLACE

• Illuminated check engine light with O2 sensor fault codes
• Noticeable drop in fuel economy
• Rough idle, hesitation or poor performance
• Failed or borderline emissions test results

TESTING & DIAGNOSIS

Before replacement, suspected sensors can be checked with a multimeter or scan tool to confirm correct voltage, resistance and signal response. Replacing a faulty sensor restores accurate ECU feedback and helps protect the engine and catalytic converter from damage caused by incorrect fuelling.
