Name: Oxygen Sensor Holden Rodeo RA 3.6L V6 LCA 2006-2008 Pre-Cat Wideband
Brand: Aftermarket OEM Replacement
SKU: COS1194-RODEO
Price: 143.66 AUD
Availability: InStock

BRAND NEW wideband oxygen sensor (broadband lambda) to suit Holden Rodeo RA 3.6L V6 LCA 2006-2008.

If your Rodeo RA 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 for the 3.6L LCA V6 - dispatched same-day before 12pm from Cranbourne VIC.

TO SUIT

Designed for Holden Rodeo RA TFR27 and TFS27 3.6L V6 LCA (H9) 157kW (January 2006 to June 2008). Covers Ute and Platform/Chassis cab configurations.

PACKAGE INCLUDES

1 x BRAND NEW wideband oxygen / lambda sensor. 6-pin connector, 5-wire, M18x1.5 thread, 670mm cable. Pre-cat upstream fitment. Direct plug-in replacement - no wiring modification required.

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 Rodeo RA 3.6L LCA V6, the wideband lambda sensor is mounted upstream before the catalytic converter. The Rodeo RA shares the same OEM sensor (12575904) with the Colorado RC, both running the LCA (H9) engine. A failing sensor causes the ECU to run on open-loop fuel control, leading to rich running, increased fuel consumption, and loss of power.

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.
