2015 Holden Commodore crank-angle sensor: what it does and how to look after it

A crank-angle sensor (also called a crankshaft position sensor) is fitted to all 2015 Holden Commodore engines, including the 3.0L/3.6L SIDI V6 and the 6.0L V8. This is confirmed by Holden/GM Global Service Information (VF Commodore Engine Controls sections for LFX V6 and L77 V8), the VF Commodore service manual diagnostic charts for DTC P0335–P0339, and ACDelco parts catalogues that list a CKP sensor for these variants. So yes, it’s relevant and present on the 2015 model range.

This little sensor does a big job. It reads a toothed wheel on the crankshaft and tells the engine computer exactly where the crank is and how fast it’s spinning. With that info, the ECU times spark and fuel precisely, manages starting, and watches for misfires. If the signal drops out or goes wonky, the Commodore can be hard to start, stall when hot, or throw a check-engine light.

Owners will typically notice:

• Long cranking, intermittent no-start, or stalling after warm-up
• Tacho flicking to zero, rough running, reduced power, or limp mode
• Fault codes like P0335–P0339 (crankshaft position sensor circuit/performance)

It isn’t a scheduled replacement item, it’s solid-state and sealed. As part of servicing, the smart move is to keep an eye on wiring and connectors around the rear of the engine/bellhousing area (where the sensor usually lives on both V6 and V8), check for oil leaks or heat damage, and make sure loom clips and shielding are intact.

When replacement is needed, going with an OE-quality sensor is the safest bet. A sensible approach is:

1. Disconnect the battery, raise the vehicle safely, and gain access from underneath.
2. Unplug the harness, remove the retaining bolt, and twist the sensor free.
3. Lightly oil the new O-ring, install, and torque to the spec in the service manual.
4. Clear codes and perform a crank variation learn (some ECUs relearn automatically after a few drive cycles, but a scan tool procedure is best).

Tech sources worth noting: Holden/GM Global Service Information (VF Commodore Engine Controls – LFX V6 and L77 V8, DTC P0335 diagnostics) and ACDelco parts catalogues for VF CKP sensors. Together they confirm the part, its function, locations, and the relearn procedure expectations.

Popular questions

Where is the crank-angle sensor on a 2015 Holden Commodore?

On the V6 (SIDI), it’s typically mounted at the rear of the engine block reading a reluctor on the crank, accessed from near the bellhousing. On the 6.0L V8, it’s also at the rear of the block, close to the transmission area. Access is usually from underneath once splash shields are out of the way.

Exact placement can vary slightly by engine and production run, so checking the VF service manual diagrams helps pinpoint it quickly.

Does a crank-angle sensor replacement need a relearn?

Yes, a crankshaft position variation learn is recommended after replacement. Many VF ECUs will adapt over a few drive cycles, but a scan-tool relearn locks timing and misfire detection in faster and more accurately. It’s a quick procedure most workshops can handle.

Can the Commodore be driven with a failing crank-angle sensor?

It might run intermittently, but it’s risky. A marginal sensor can cause sudden stalling, hard restarts, and limp mode. If codes like P0335 pop up or it stalls when hot, it’s best to schedule diagnosis and replacement rather than hope it comes right.
