Parts for your 2015 Holden Captiva 5-Map sensor

2015 Holden Captiva 5 MAP sensor — what it does and when to service it

Technical sources confirm the 2015 Holden Captiva 5 is fitted with a Manifold Absolute Pressure (MAP) sensor. Holden/GM Service Information (SI) for MY15 Captiva/Antara lists the MAP sensor in Engine Controls for both the 2.4‑litre petrol and 2.2‑litre diesel, with related diagnostic codes P0106, P0107 and P0108. The ACDelco GM Genuine Parts catalogue also carries a MAP sensor application for Captiva 5, further verifying fitment.

On this model, the MAP sensor constantly reads the pressure (vacuum/boost) inside the intake manifold and feeds that to the engine control module. The ECM uses that signal to juggle fuel, ignition timing, EGR operation and throttle strategy. On 2.4‑litre petrol Captiva 5s that also run a MAF, the MAP backs up the MAF and improves accuracy under rapid throttle changes and at different altitudes. On the 2.2‑litre diesel, it doubles as a boost/soot watcher, helping control turbo boost and EGR, and flagging when the manifold is gummed up.

There’s no fixed replacement interval in the factory schedule, but it’s smart maintenance to keep it clean and healthy. A Captiva 5 that shows slack throttle response, rough idle, higher fuel use, diesel smoke under load, or throws a check‑engine light with P0106–P0108 could be telling them the MAP sensor is reading off.

• Location: typically on the intake manifold near the throttle body on the 2.4 petrol, on or near the manifold/charge pipe on the 2.2 diesel.
• Service tip: at regular services, inspect the connector and wiring, and look for oil mist or soot build‑up around the sensor port.
• Cleaning: with the engine off, unplug it and remove the retaining screw. Use sensor‑safe electronics cleaner only, avoid harsh solvents or compressed air. Let it dry fully and refit with the O‑ring intact.
• Replacement: if cleaning and wiring checks don’t restore proper readings, fit a quality OE‑spec unit. Lightly lubricate the O‑ring, seat the sensor squarely, tighten the fastener to spec, clear any codes and perform an idle relearn if required by the scan tool.

For diesel owners, consider checking/cleaning the MAP every 40–60,000 km (more often if most driving is short trips). Petrol models generally need less frequent attention, but a quick look at major services helps keep fuel economy and drivability on song.

Popular questions about 2015 Holden Captiva 5 MAP sensors

Where is the MAP sensor on a 2015 Holden Captiva 5?
On the 2.4‑litre petrol, it’s mounted on the intake manifold close to the throttle body, held by a single screw and sealed by an O‑ring. On the 2.2‑litre diesel, it’s typically on the manifold or charge pipe, near the EGR/throttle mixer where soot can accumulate.

Does the Captiva 5 use both a MAF and a MAP sensor?
Yes, many 2.4 petrol Captiva 5s use both. The MAF measures incoming air mass, while the MAP tracks manifold pressure. The ECM blends both signals for accurate fueling and uses the MAP as a sanity‑check if the MAF misreads.

Can a bad MAP sensor harm the engine?
It won’t usually cause immediate damage, but it can lead to rich or lean running, poor economy and sluggish performance. On diesels, incorrect readings can upset boost control and DPF strategy. Sorting it early prevents knock‑on issues like fouled plugs (petrol) or excessive soot (diesel).
