Parts for your 2006 Holden Commodore-Crank angle sensor

2006 Holden Commodore crank angle sensor

Technical service literature and parts catalogues confirm the 2006 Holden Commodore does use a crank angle sensor (also called a crankshaft position sensor, CKP). It’s fitted across 2006 VZ and early VE models, including the 3.6-litre Alloytec V6 and the 6.0-litre V8. This sensor is critical to engine management and is a known service/diagnostic item on these engines.

• Holden/GM GlobalTIS and VE Commodore Service Manual: Engine Controls – procedures for “Crankshaft Position Sensor – Replace/Diagnose” (3.6L LY7, 6.0L L76).
• Gregory’s/Haynes workshop manuals for Commodore VZ–VE: Engine management section lists CKP sensor testing and fault codes.
• ACDelco and Bosch Australian catalogues: CKP sensor listings for 2006 Commodore 3.6 V6 and 6.0 V8 applications.
• Autodata/Repco trade data: Diagnostic trouble codes P0335–P0339 and replacement guidance for Commodore CKP.

The crank angle sensor on a 2006 Holden Commodore keeps the ECU in the loop about where the crankshaft is and how fast it’s spinning. That live feed lets the computer time spark and fuel bang-on, and keeps it synced with the cam sensor so the injectors fire on the right stroke. If the signal drops out, the engine can stumble, stall, or not start at all.

It’s not a scheduled replacement item, but it’s smart to give it attention during servicing. They’ll check the wiring loom for chafing, heat damage or oil soak, make sure the connector pins are clean and tight, and confirm the sensor is mounted firmly. Typical red flags are hard starting when hot, random stalling, rough idle, or a dead crank with no fire. The dash may light up the MIL and store codes like P0335–P0339.

• If replacement’s needed, use a quality OE-equivalent sensor and a fresh O-ring (where fitted).
• Battery off, vehicle safely supported, and let hot engines cool before working near the exhaust.
• Route the harness in the factory clips to keep it away from headers and moving parts.
• A CKP variation relearn (CASE) with a capable scan tool is often recommended, some ECUs adapt after a few drive cycles, but a relearn gives the best result.

Location varies by engine: most Alloytec V6s place the CKP low at the rear of the block near the bellhousing, many Gen IV 6.0 V8s mount it in the front timing cover by the crank pulley. Access ranges from straightforward to a bit fiddly. If the car is cutting out or won’t restart when warm, don’t keep pushing your luck—get it tested and sorted before it leaves you stranded.

FAQs

Where is the crank angle sensor on a 2006 Holden Commodore?
On most 3.6L Alloytec V6s it’s mounted low at the back of the engine near the transmission bellhousing. On many 6.0L V8 L76 engines it sits in the front timing cover close to the crank pulley. Exact placement can vary, so a quick look-up by engine code helps.

What are the symptoms of a failing crank angle sensor?
They’ll often see hot no-start, intermittent stalling, rough idle, misfires, or sudden loss of power. The check engine light may appear with codes like P0335. As the fault worsens, it can turn into a complete no-start.

Do you need a relearn after replacing the sensor?
A crankshaft variation relearn (often called CASE) is recommended with a suitable scan tool. Some ECUs will relearn over a few drive cycles, but performing the procedure speeds things up and ensures crisp starting and stable idle.
