Parts for your 2010 Holden Captiva 7-Crank angle sensor

2010 Holden Captiva 7 crank-angle sensor (crankshaft position sensor)

Based on OEM service documentation, the 2010 Holden Captiva 7 does use a crank‑angle sensor (commonly called a crankshaft position sensor or CKP). GM Service Information (SI) for the Captiva CG series (2010) lists the CKP under Engine Controls for the 2.4L LE5 petrol, 3.2L LY7 V6 petrol, and 2.0L VCDi diesel, with diagnostic procedures for DTCs P0335/P0336 and a crank variation learn. Holden Workshop Manual, Captiva CG, Section 6E – Engine Controls, also details sensor description, location and testing. For the diesel variant, Bosch EDC16/EDC17 engine management references confirm a dedicated crankshaft speed/position sensor is required for injection timing.

On the 2010 Captiva 7, the crank‑angle sensor tells the engine control module exactly where the crankshaft is and how fast it’s spinning. That information is vital for spark timing on the petrol engines and injection timing on the diesel. If it goes out of whack, the ECM can’t sync fuel and spark properly, which can cause hard starts, random stalling, rough running, or a no‑start. It’s a small part with a big job, sitting near the crank centreline (location varies a touch by engine: typically low on the block or at the bellhousing reading the reluctor/flywheel teeth).

It’s not a routine “replace by kilometres” item, but it is worth a look during servicing. A quick visual of the connector and harness routing, especially near the exhaust and driveshafts, helps prevent heat or chafe damage. Light oil weepage at the rear of the engine can contaminate the sensor or connector, so cleaning and fixing the leak goes a long way.

• Common symptoms of a failing CKP: extended crank or no‑start, intermittent stall when hot, erratic tacho, reduced power, and fault codes P0335/P0336.
• Basic checks: scan for codes and live RPM data, inspect the plug for oil ingress or green corrosion, and wiggle‑test the loom for dropouts.

Replacement is straightforward with the right access: disconnect the battery, raise the vehicle safely, unplug the sensor, remove its retaining bolt, and ease it out (there’s an O‑ring). Lightly oil the new O‑ring, seat the sensor squarely, and torque the bolt to spec. After fitting, a crankshaft position system variation learn (often called a CASE relearn) using a suitable scan tool is recommended by GM SI so the ECM can recalibrate misfire diagnostics and timing correlation. That relearn step is the difference between “it runs” and “it runs right”. Reputable aftermarket sensors work fine, but OE‑quality Hall‑effect/magnetic sensors tend to be more stable with heat, which Captiva engines see plenty of in Aussie and Kiwi conditions.

Where is the crank‑angle sensor on a 2010 Holden Captiva 7?

It’s mounted near the crankshaft centreline. On the 2.4L petrol it’s typically low on the block near the transmission side, on the 3.2L V6 it’s accessed from underneath at the rear of the block, on the 2.0L diesel it commonly reads the flywheel at the bellhousing. A torch and a mirror help, and removing a splash shield often improves access.

What are the signs the crank‑angle sensor is failing?

Look for intermittent hot‑start issues, sudden stalling, uneven idle, or a dead‑crank no‑start. The tacho may drop to zero unexpectedly. Scan tools often show P0335 or P0336, or an implausible RPM signal during cranking.

Do you need a relearn after replacing the sensor?

Yes, GM SI specifies performing a crankshaft position variation learn (CASE relearn) with a capable scan tool after replacement. The car may start without it, but the relearn sharpens timing correlation and restores accurate misfire monitoring.
