2011 Holden Captiva 5 Camshaft Sensor — What It Does and When To Replace It

Yes, the 2011 Holden Captiva 5 uses a camshaft position sensor (CMP). Technical references including the Holden/GM Global Service Information (CG Captiva engine controls), the Opel Antara/GM powertrain documentation for the 2.4‑litre DOHC petrol, and mainstream parts catalogues for GM Genuine Parts/ACDelco all list camshaft position sensor(s) for this model. On the 2.4‑litre petrol with dual VVT there are typically two CMP sensors (intake and exhaust), while the common‑rail diesel variant uses a single cam sensor along with the crank sensor for timing.

On this Captiva 5, the camshaft sensor tells the engine computer exactly where the cams are in their rotation. That live position data is crucial for three things: precise fuel injection timing, accurate spark timing on coil‑on‑plug ignition, and feedback control for the variable valve timing. Without a clean signal the ECU can’t sync the show properly, which can lead to hard starting, rough idle, sluggish performance, or the dreaded check engine light. Common fault codes include P0340, P0341 or P0365, depending on which cam and bank the ECU isn’t happy with.

It’s not a scheduled replacement item in normal servicing, but it pays to keep an eye on it. At regular service intervals (say each 10,000–15,000 km), a tech will usually scan for stored codes, check the wiring and connector under the bonnet, and make sure there’s no oil wicking into the plug. Using the correct, clean engine oil is also key—sludgy oil can upset VVT operation and contaminate the sensor area over time.

Replacement is straightforward for most trims: disconnect the battery negative, unplug the connector, remove the retaining bolt, and ease the sensor out. A light smear of clean oil on the new O‑ring helps it seat without tearing. Fit the new sensor, torque the bolt to spec, reconnect and clear codes. Some Captiva engines will perform a self‑learn, if not, a quick cam/crank relearn with a scan tool finishes the job. Go OE or reputable OE‑equivalent—cheapies can throw noisy signals and bring the light back on.

Signs it’s time to act include intermittent no‑start when hot, sudden loss of power, poor fuel economy, or ongoing misfire that doesn’t move with coils or plugs. If those crop up, a scan and live‑data check will usually pinpoint the culprit. Done right, a cam sensor swap is a tidy, driveway‑friendly fix that restores smooth running and keeps the Captiva’s VVT behaving as it should.

• Typical symptoms: hard start, rough idle, flat spots, check engine light (P0340/P0341/P0365).
• Good practice: inspect wiring/connector, maintain correct oil spec and intervals, use quality parts.
• After replacement: clear codes and perform cam/crank relearn if required.

Popular questions

Where is the camshaft sensor on a 2011 Captiva 5?
On the 2.4‑litre petrol it’s mounted at the end of each camshaft in the top of the cylinder head—one for the intake cam and one for the exhaust cam. They sit under the engine cover, with a small single bolt holding each sensor. On the diesel, the single cam sensor is also at the top end of the engine near the timing cover.

Do I need to replace both cam sensors on the 2.4‑litre if only one fails?
Not necessarily. If diagnostics and codes point to just the intake or the exhaust sensor, replacing the faulty one is fine. That said, on higher‑kilometre cars it’s reasonable to pre‑emptively replace the pair if labour access is the same and you want to avoid a second visit.

Will a bad cam sensor damage the engine?
It’s unlikely to cause mechanical damage by itself. The ECU will usually fall back to a safe strategy, but you’ll notice poor running and higher fuel use. Prolonged misfires can load up the catalytic converter, so it’s best to diagnose and fix the issue promptly.
