Parts for your 2007 Holden Captiva 5-Camshaft sensor

2007 Holden Captiva 5 camshaft sensor — what it does and how to look after it

Based on technical sources including the Holden CG Captiva Service Manual (Engine Controls), GM Global Service Information for 2007 Captiva/Antara, and the Holden/ACDelco Electronic Parts Catalogue for the 2007 VIN range, the 2007 Holden Captiva 5 is fitted with a camshaft position sensor. Both the 2.4‑litre four‑cylinder and the 3.2‑litre Alloytec V6 use camshaft position sensing, the V6 employs a sensor on each bank. So the camshaft sensor is definitely relevant to this model.

The camshaft sensor on a 2007 Holden Captiva 5 feeds the engine control module precise information about where the cam(s) are in their rotation. That lets the ECM fire the injectors and coils at the right moment and manage any variable valve timing gear so the engine starts crisply, idles smoothly, and doesn’t waste fuel. If the sensor signal goes walkabout, the ECM can fall back on the crank sensor to keep the show on the road, but owners will notice long cranks, doughy throttle response, and a lit check engine lamp.

It’s not a scheduled service item, but it does benefit from a quick look during routine servicing. Heat, vibration, and a light oil weep can harden the sensor’s O‑ring or wick oil into the plug. A tech should check the connector for brittle insulation, green corrosion, or oil contamination, and make sure the sensor body is seated squarely in the head.

• Common symptoms: hard starting, rough idle, reduced power, poor economy, and DTCs such as P0340/P0341 (and on V6s, bank‑specific codes).
• Replacement tips: key off, remove the engine cover, unplug the connector, pull the retaining bolt, twist and withdraw the sensor, fit a fresh O‑ring lightly oiled, refit and tighten to the workshop‑manual spec, reconnect, clear codes, and warm‑up test.
• Quality matters: use OE or OE‑equivalent parts so the waveform and timing are spot on. Cheap sensors often cause intermittent faults.

Most Captiva 5s don’t need programming after a cam sensor swap, the ECM will relearn on its own after a few drive cycles. A shop scan tool can run a cam/crank correlation check if the light returns. For the 3.2 V6, remember there’s a sensor on each bank—diagnose before replacing both.

Keeping the sensor clean, dry, and properly sealed goes a long way to avoiding random no‑start dramas and keeping the Captiva 5 running sweet as on Kiwi and Aussie roads.

Popular questions

Where is the camshaft sensor on a 2007 Holden Captiva 5?
On the 2.4‑litre, it’s mounted at the cylinder head near the cam cover, accessible once the engine cover is off. On the 3.2‑litre V6 there’s one on each bank, near the front of the heads. The exact spot varies slightly by engine code, but all are a short, single‑bolt sensor with a two‑ or three‑pin plug.

What fault codes point to a bad camshaft sensor?
Typical Captiva 5 codes include P0340 and P0341 for camshaft position circuit/performance. V6 models may show bank‑specific codes (e.g., intake or exhaust, Bank 1 or Bank 2). Pairing symptoms like long cranks or a rough idle with these codes is a strong hint the sensor or its wiring needs attention.

Does a camshaft sensor need programming after replacement?
Generally no. The ECM will adapt after a few starts and a short drive. Clear stored codes, then road‑test. If a code returns, a workshop can perform a cam/crank correlation check with a scan tool and verify wiring integrity and timing marks.
