96958775 Car Oxygen Sensor For Chevrolet Daewoo Holden (Australia / New Zealand) Opel / Vauxhall

This Lambda Sensor replaces the following Original Equipment Manufacturer (OEM) and interchange part numbers. Check your old sensor to confirm a match:

Note: Always verify physical fitment before purchasing, as aftermarket interchange numbers may not be identical in all applications.

This Lambda Sensor is primarily used in General Motors (GM) vehicles, particularly Chevrolet and Daewoo models from the early to mid-2000s. It also fits certain Opel / Vauxhall models.

Please verify the connector shape and wire length with your old unit before purchasing.

Note: This sensor is typically located in the upstream (pre-catalyst) or downstream (post-catalyst) position depending on the specific vehicle configuration. Verify your vehicle's requirements before ordering.

Consider replacing your Lambda Sensor if you experience any of the following:

• Illuminated Check Engine Light – OBD-II fault codes related to oxygen sensor circuit (e.g., P0130-P0167 range)

• Increased Fuel Consumption – A faulty sensor may cause the engine to run rich (excess fuel) because the ECU cannot accurately adjust the air-fuel mixture

• Poor Engine Performance – Hesitation, stumbling, surging, or lack of power during acceleration

• Rough Idle – The engine may idle erratically or stall unexpectedly

• Failed Emissions Test – High hydrocarbon (HC) or carbon monoxide (CO) readings due to incorrect combustion

• Rotten Egg Smell (Sulphur Odour) – Indicates a rich-running condition that may damage the catalytic converter

• Black Smoke from Exhaust – Sign of excessive fuel in the combustion mixture

Potential causes of sensor failure:

• Normal wear and tear over mileage (typically 60,000 - 100,000 miles / 100,000 - 160,000 km)

• Contamination from oil, coolant, or silicone sealants

• Heater circuit electrical failure

• Physical damage from road debris or improper handling

• This is a direct-fit sensor with a specific 4-pin female black connector. It is not a universal splice-in sensor.

• Always cross-reference your old sensor's part number, connector shape, and wire length (approx. 680mm) before ordering.

• While this OE number is listed for Chevrolet, Daewoo, Opel, and Holden, connector designs may vary subtly by market. Physical inspection of your original sensor is strongly recommended.

• This part number (96958775) is commonly used as a pre-catalyst (upstream / Bank 1 Sensor 1) sensor for many Aveo and Kalos applications.

• However, some configurations may use it downstream. Check your vehicle's service manual or the location of your old sensor before purchasing.

• If you need a downstream sensor for the same vehicle, a different part number may be required.

• Allow the exhaust system to cool completely before removal to avoid burns and prevent thread damage.

• Use an O2 sensor socket (22mm or 7/8") to prevent stripping the sensor during removal/installation.

• Apply anti-seize compound to the threads of the new sensor (avoiding the sensor tip) to prevent seizing in the exhaust bung over time. Check if your sensor comes with pre-applied anti-seize.

• Do not use silicone sealants near the exhaust system, as they can contaminate and destroy the sensor.

• Avoid touching the sensor tip – oils from your skin can contaminate the element and cause premature failure.

• Tighten to the correct torque – Typically 40-50 Nm (30-37 ft-lb). Overtightening can damage threads.

• Lambda sensors degrade over time, even without fault codes. Replacement every 100,000 miles (160,000 km) is recommended to maintain:

  • Optimal fuel efficiency (potential savings of up to 15%)

  • Catalytic converter health and longevity

  • Lower emissions output

• Quality aftermarket Lambda Sensors typically come with a warranty period (e.g., 12 months / 20,000 km to 2 years / unlimited mileage). Check with your specific retailer for their warranty terms and return policy.

• While this is a direct-fit part, professional installation is recommended if you are not experienced with automotive exhaust systems. Improper installation can lead to:

  • Exhaust leaks around the sensor bung

  • Cross-threaded or damaged exhaust manifold threads

  • Sensor damage from dropping or contamination

  • Wiring damage from contact with hot exhaust components

• O2 sensor socket (22mm / 7/8") or deep offset wrench

• Ratchet and extension bar (for access)

• Anti-seize compound (if not pre-applied)

• Jack and jack stands (if safe under-vehicle access requires lifting)
