2016 Holden Captiva 7 Camshaft Sensor — purpose, fitment and servicing tips

Yes, the 2016 Holden Captiva 7 uses a camshaft position sensor (CMP). Technical sources including GM/Holden Service Information (CG/MY16), the Holden Electronic Parts Catalogue, and common OEM parts catalogues (e.g., ACDelco/Delphi) all list a CMP for the Captiva 7’s engines. GM diagnostic procedures also reference CMP-related DTCs such as P0340/P0341 (intake) and P0365/P0366 (exhaust), confirming the sensor is fitted across the 2.4L petrol four, 3.0L V6 petrol and 2.2L turbo-diesel variants.

On the Captiva 7, the camshaft sensor’s job is to tell the engine control module exactly where the cam(s) are in their rotation. That lets the ECU synchronise sequential fuel injection, fire the coils at the right time and manage variable valve timing. When the CMP signal goes missing or erratic, drivers can see hard starting, rough idle, sluggish performance, poor fuel economy and a glowing check-engine light. The ECU may fall back to a limp strategy using the crank sensor, but drivability won’t be flash.

It’s not a scheduled-service item, but it’s smart to give it a look during regular servicing. A few quick checks help avoid headaches:

• Inspect the plug and wiring for oil intrusion, broken clips or chafing near the timing cover.
• Keep an eye out for weeping rocker cover gaskets that can oil-soak the connector.
• Scan for stored or pending CMP-related fault codes if the idle isn’t right.

Replacement is straightforward with basic hand tools. Typically, the sensor sits on the cylinder head near the timing cover (the 2.4L petrol commonly has two sensors: one for intake, one for exhaust, the 3.0L V6 has one per bank). Disconnect the battery negative, unplug the connector, remove the retaining bolt, and gently twist the sensor free so the O-ring doesn’t tear. Lightly oil the new O-ring, seat the sensor squarely and tighten the bolt to spec per the service manual. Always route the harness as original and avoid swapping the intake and exhaust connectors if there are two sensors.

After fitting, clear codes and road test. Some scan tools will prompt a cam/crank correlation or idle relearn—do that to keep the ECU happy. If CMP codes return, don’t overlook mechanical timing issues like a stretched chain or a misaligned timing job, which can mimic a dodgy sensor.

FAQs

How many camshaft sensors does a 2016 Captiva 7 have?
It depends on the engine. The 2.4L petrol typically runs two sensors (intake and exhaust), the 3.0L V6 has one per bank, and the 2.2L diesel usually has a single cam sensor. Always confirm by VIN/engine code or a quick visual under the bonnet.

Do new camshaft sensors need programming?
Generally, no. Fit the sensor, clear the codes and perform an idle or cam/crank correlation relearn if your scan tool requests it. If a fault returns, check wiring and mechanical timing before blaming the new part.

Can a faulty camshaft sensor cause a no-start?
It can cause long cranking and rough starting, and in some cases a start-then-stall. The ECU may attempt fallback using the crank sensor, but if the CMP signal is wildly off or there’s a wiring fault, it can be a full no-start.
