2014 Holden Commodore crank-angle-sensor: purpose, fitment and service tips

Yes, the 2014 Holden Commodore is fitted with a crank-angle-sensor (more commonly listed by Holden/GM as the crankshaft position sensor, CKP). This is confirmed in GM Service Information for the VF Commodore (Engine Controls, DTC P0335–P0339 diagnostic sections) and the Holden VF workshop manual, both of which describe sensor location, fault codes and replacement procedures. ACDelco/GM parts catalogues for the VF’s V6 (LFX) and V8 (L77) engines also list the CKP as a serviceable component.

On the VF Commodore, the crank-angle-sensor is the engine’s timekeeper. It reads a toothed reluctor wheel on the crankshaft and feeds the ECU exact crank position and speed. The ECU then syncs fuel injection and spark timing to the degree, which keeps starting crisp, idle smooth and power delivery clean. If the signal drops out, the engine can crank without firing, stall, or run roughly as the ECU loses its timing reference.

Owners will typically see a Check Engine light with codes like P0335/P0336 if the sensor or its wiring is unhappy. Other tell-tales include hard starting, intermittent stalling at lights, tachometer flicks, and misfire-like surging. Because the sensor sits low on the block, heat, vibration and oil contamination can take a toll over time.

There’s no scheduled replacement interval for the CKP on a VF, it’s a “fix when faulty” item. Preventative care is mostly about inspection: check the wiring loom for chafe, make sure the connector is clean and locked, and keep oil leaks sorted so they don’t wick into the plug. When replacement is required, use a quality OEM-spec sensor (ACDelco or equivalent) and a fresh O-ring.

• Location: typically low and towards the rear of the engine block. On the L77 V8 it’s near the starter/bellhousing area, on the LFX V6 it’s mounted low in the block, accessed from underneath.
• Replacement basics: disconnect the battery, safely raise and support the vehicle, unplug the connector, remove the retaining bolt, twist the sensor free, lubricate the new O-ring with clean engine oil, seat the sensor fully and tighten the bolt to the factory spec in GM SI.
• Post-fit step: perform a crank variation relearn (CASE relearn) with a suitable scan tool so the ECU stores the new signal profile.

Done right, a fresh crank-angle-sensor restores rock-solid starts and smooth running, keeping the VF Commodore feeling spot on for the long haul.

FAQs

Where is the crank-angle-sensor on a 2014 VF Commodore?
It’s mounted low on the engine block by the crankshaft. On the L77 V8 it’s near the starter and bellhousing area, on the LFX V6 it’s low at the rear of the block, usually accessed from underneath with the splash shield removed.

What are common symptoms of a failing crank-angle-sensor?
Hard starting or a no-start when hot, random stalling, rough idle, tachometer dropouts, and a Check Engine light with codes like P0335/P0336 are common. Wiring or connector issues can mimic a bad sensor, so testing is wise before replacing.

Does the crank-angle-sensor need regular servicing?
There’s no routine service interval. It’s replaced when it fails. During servicing, a quick check of the harness and connector for oil, heat damage, or chafing helps prevent intermittent faults.
