BRAND NEW *OEM Quality* wideband oxygen sensor (broadband lambda) to suit Holden Commodore VZ/VE / Adventra / Berlina / Calais / Crewman / One Tonner / Caprice WL/WM / Statesman WL/WM / Colorado RC / Rodeo RA 3.6L V6.

If your Holden has a Check Engine light with O2 sensor codes, is running rich, or showing poor fuel economy, a failed wideband lambda sensor is a common cause. This is the pre-cat upstream sensor covering the full 3.6L Alloytec V6 range - dispatched same-day before 12pm from Cranbourne VIC.

TO SUIT

Designed for the full 3.6L Alloytec V6 range across Commodore VZ and VE Sedan/Ute/Wagon (2004-2013), Adventra VZ Wagon AWD, Berlina VZ and VE, Calais VZ and VE, Crewman VZ, One Tonner VZ, Caprice WL and WM, Statesman WL and WM, Colorado RC Ute/Platform (2008-2012), and Rodeo RA Ute/Platform (2006-2008). Covers all engine variants including LY7/LLT/LFX and LPG dual fuel.

FITMENT CHECK

Left bank (pre-cat upstream) position only on the Adventra VZ - confirm which bank before ordering. All other applications use a single pre-cat sensor. Colorado RC and Rodeo RA use the same OEM sensor at this location.

ABOUT THIS SENSOR

This is a broadband wideband lambda sensor (LSU 4.2 type) - not a standard narrowband O2 sensor. The wideband sensor measures a much wider range of air-fuel ratios, providing the ECU with precise fuel mixture feedback across the full operating range rather than just a rich/lean signal.

On the 3.6L Alloytec V6 engine, the wideband lambda sensor is mounted upstream before the catalytic converter. A failing sensor causes the ECU to run on open-loop fuel control, leading to rich running, increased fuel consumption, and loss of power. This same sensor part number covers the full Alloytec V6 family from VZ through to the Colorado RC and Rodeo RA applications.

COMMON SYMPTOMS OF FAILURE

Check Engine light with codes P0130 P0131 P0132 P0133 P0134 P0135 P0136
Engine running rich - increased fuel consumption or black smoke
Loss of power or flat spots in acceleration
Failed emissions test
Poor idle quality or hesitation
Catalytic converter damage from prolonged rich running

How do I replace an oxygen sensor?

Most O2 sensors thread directly into the exhaust pipe or manifold. You will need an O2 sensor socket (22mm with a slot for the wire) and penetrating oil if the sensor is seized. Allow the exhaust to cool completely before starting. Some sensors also require a wiring harness connector to be unplugged. Always clear fault codes with an OBD2 scanner after replacement.

What fault codes does a faulty O2 sensor trigger?

A faulty O2 sensor typically triggers codes P0130 to P0167. The specific code indicates which sensor has failed - P0130 to P0138 relate to Bank 1 sensors and P0150 to P0158 relate to Bank 2 sensors. An OBD2 scanner will identify the exact sensor location.

Can I use a universal O2 sensor on my vehicle?

Universal sensors can work but require splicing the wiring harness which introduces risk of connection faults. A direct-fit aftermarket OEM replacement sensor with the correct connector plugs directly in with no cutting or splicing required. SensorGal stocks direct-fit sensors cross-referenced to OEM part numbers for most Australian vehicles.

How do I know if my O2 sensor is bad?

Common signs include poor fuel economy, rough idle, failed emissions test, rotten egg smell from the exhaust, and a Check Engine light with codes P0130-P0167. An OBD2 scanner showing a flat or sluggish O2 sensor waveform on live data also indicates a faulty sensor.

What is the difference between upstream and downstream O2 sensors?

The upstream (pre-cat) sensor monitors exhaust gases to help the ECU calculate fuel trim. The downstream (post-cat) sensor monitors catalytic converter efficiency. They serve different functions and are not interchangeable even if they look identical.

Can a bad O2 sensor damage my catalytic converter?

Yes. A faulty upstream O2 sensor can cause the engine to run rich, sending unburnt fuel into the catalytic converter. Over time this overheats and destroys the catalyst. Replacing the O2 sensor promptly protects your catalytic converter.

How many O2 sensors does my vehicle have?

Most 4-cylinder vehicles have two O2 sensors (one upstream, one downstream). V6 and V8 engines typically have four - one upstream and one downstream per bank. Contact us with your vehicle details and we will confirm the correct quantity and part numbers.
