Parts for your 2015 Holden Captiva 5-Crank angle sensor

2015 Holden Captiva 5 crank angle sensor – what it does and when to replace it

Technical sources confirm the 2015 Holden Captiva 5 is fitted with a crank angle sensor (also called a crankshaft position or CKP sensor). Holden/GM Service Information for the CG Captiva (Engine Controls – Crankshaft Position Sensor), the Holden Electronic Parts Catalogue for CG Captiva 2015 2.4L (LE9), and ACDelco parts listings all specify a CKP sensor for this model, making it a relevant and critical engine management component.

On the Captiva 5’s 2.4‑litre petrol engine, the crank angle sensor constantly tracks crankshaft speed and position using a toothed reluctor wheel. The engine control module then uses that signal to time spark and fuel injection, stabilise idle, and coordinate with the cam sensors for variable valve timing. If the CKP signal drops out or drifts, the Captiva can be hard to start, misfire, stall at idle, or throw the check‑engine light with codes like P0335/P0336.

There’s no scheduled replacement for the CKP sensor, it’s a “replace on fault” item. During regular servicing, good workshops will scan for stored fault codes and review live data to confirm a clean, stable crank signal—especially if the owner reports intermittent stalling or no‑start when hot. If replacement is required, the sensor is mounted on the engine block (rear side on the 2.4 LE9), reading the crank reluctor through the housing. Access varies by tools and lift, but the job is straightforward for a trained tech.

• Typical symptoms: long crank/no start, sudden stall, rough running, poor fuel economy, CEL on with CKP codes.
• Basic checks first: battery/earth health, harness chafe near the sensor, oil contamination at the connector, and correct gap/fitment.
• Replacement tips: use a quality OE‑equivalent sensor, lightly oil the O‑ring, seat fully, and torque to service‑manual spec. Clear codes and complete a road test to confirm stable RPM and no pending faults.

Owners who mainly drive short trips or in hot conditions should be extra alert to heat‑soak no‑start symptoms, as marginal sensors often show up after a hot shut‑down. Because a failing CKP can cause sudden stalling, it’s not something to put off—book it in promptly if those warning signs appear.

Popular questions

Where is the crank angle sensor on a 2015 Captiva 5?
On the 2.4‑litre petrol, it’s mounted on the rear side of the engine block, reading the crankshaft’s reluctor wheel through the housing. Access is from underneath on most hoists, on the driveway, removing lower shields can help visibility. Always disconnect the battery and let the engine cool before working near the sensor.

Can a bad CKP sensor cause the Captiva 5 to stall at traffic lights?
Yes. A weak or intermittent crank signal can cut spark and fuel synchronisation, causing an abrupt stall, often with a longer crank to restart. If that’s happening, it’s wise to scan for CKP‑related codes and address it quickly for safety and to avoid being stranded.

Do CKP sensors need routine servicing?
No scheduled service is required. However, during regular servicing a technician should inspect the harness and connector for oil ingress or damage, verify clean signal data on a scan tool, and update the engine ECU if a calibration is available to improve hot‑restart behaviour.
