Parts for your 2010 Holden Captiva 5-Crank angle sensor

2010 Holden Captiva 5 crank-angle sensor: what it does and how to look after it

Based on technical sources including GM Service Information (SI) for the 2010 Captiva/Antara Powertrain – Engine Controls (Crankshaft Position Sensor Description and Operation, DTC P0335–P0339), the Holden CG Captiva workshop manual (Engine Control section), and OE parts catalogues from ACDelco/Delphi/Bosch listing a crankshaft position sensor for the 2010 Captiva 5 2.4‑litre petrol, this model is fitted with a crank-angle sensor (also called a crankshaft position sensor, CKP). So yes, it’s relevant to the 2010 Holden Captiva 5.

The crank-angle sensor on a 2010 Captiva 5 is the quiet achiever that lets the engine computer know exactly where the crank is and how fast it’s spinning. Using a magnetic or Hall-effect pickup aimed at a toothed reluctor on the crankshaft, it feeds the ECU precise timing info to fire the spark and inject fuel at just the right moments. Without it, the Captiva will crank but often won’t start, or it may stall, misfire or run roughly.

On the 2.4‑litre petrol, the sensor is mounted low on the engine block, reading the crank’s reluctor wheel. There’s no set replacement interval, but it’s smart to inspect the wiring and connector during regular services, especially if there are oil leaks or road grime where the harness runs. Poor connections are a common culprit for intermittent faults.

• Typical symptoms of a failing CKP: hard starting or no-start, random stalling once warm, tachometer dropping out, uneven idle, and engine light with codes like P0335/P0336.
• Good practice when replacing: disconnect the battery, access the sensor from underneath after removing the splash shield, unbolt the sensor (usually a single small bolt), lightly oil the new O‑ring, seat it cleanly, and torque to spec. Clear fault codes and perform a crank variation relearn with a capable scan tool so the ECU can sync accurately.
• Use quality OE-equivalent parts (ACDelco/Delphi/Bosch) to avoid repeat issues, and check for oil leaks that can contaminate the connector.

Most workshops will knock this job over in under an hour if access is straightforward. If the Captiva shows the tell-tale symptoms, a quick scan and a CKP signal check will usually confirm whether the sensor or its wiring is the cause.

Popular questions

Where is the crank-angle sensor on a 2010 Holden Captiva 5?
On the 2.4‑litre petrol, it’s mounted low on the engine block where it reads a toothed wheel on the crankshaft. Access is typically from underneath after removing the front lower splash shield. The connector and wiring run close to the block, so watch for heat or oil exposure when inspecting.

Can a bad crank-angle sensor cause a no-start on a Captiva 5?
Absolutely. If the ECU can’t see a clean crank signal, it can’t time spark or fuel properly. You may get a long crank with no fire, or it may start and then stall as the signal drops out. A scan showing P0335/P0336 plus a missing or erratic RPM reading during cranking points strongly to the CKP or its wiring.

Do I need a relearn after replacing the sensor?
Yes, on these GM powertrains a crank variation relearn is recommended after CKP replacement. It helps the ECU map the exact relationship between the sensor and reluctor so timing stays spot on. Most decent scan tools can run the procedure, skipping it can leave a subtle misfire or recurring fault codes.
