Parts for your 2007 Holden Captiva 5-Map sensor

2007 Holden Captiva 5 – Is a MAP sensor fitted and what does it do?

Yes, the 2007 Holden Captiva 5 uses a MAP (Manifold Absolute Pressure) sensor. This is documented in the Holden Captiva CG Series Service Manual (2006–2011) under Engine Controls, which details the MAP sensor’s role and diagnostics for the 2.4L petrol and applicable diesel variants. GM’s diagnostic references for the CG Captiva also list DTCs P0106, P0107 and P0108 as MAP sensor-related faults. In parts catalogues for GM/ACDelco, the 2007 CG Captiva 5 is shown with an application for a MAP sensor on the intake manifold, confirming it’s a standard fitment on this model.

On the Captiva 5, the MAP sensor measures pressure in the intake manifold so the engine control module can calculate how much air is actually getting into the engine. That data keeps fuelling and ignition timing on the money, which means better drivability, decent fuel economy and lower emissions. Even on versions that also use a MAF, the MAP is still used for load calculation, altitude compensation and plausibility checks.

When the MAP sensor starts to go off, the Captiva can feel flat, chew more fuel or throw a check engine light. Common signs include hard starting, rough idle, hesitation on take-off, and codes like P0106–P0108. Because the sensor reads pressure, anything that messes with manifold vacuum—like split hoses, loose clamps or a leaky gasket—can look like a dud MAP, so it’s worth checking the plumbing first.

Replacement and maintenance are straightforward. The sensor sits on or near the intake manifold and is usually held by a small bolt with an O-ring seal. If servicing at home, disconnect the connector, remove the bolt, ease the sensor out, and inspect the port for oil mist or carbon. A light clean of the sensor tip and port with electronics-safe cleaner is fine, avoid scrubbing or using aggressive solvents. Always fit a fresh O-ring, seat the sensor squarely, and nip the bolt to spec—over-tightening can crack the housing. Clear any stored codes and take it for a quick road test to confirm trims and idle are happy.

• Inspect vacuum hoses and the PCV line for splits or loose fittings.
• Make sure the electrical connector is clean and the terminals are snug.
• If faults persist after cleaning and hose checks, replace the sensor with a quality unit.

Where is the MAP sensor on a 2007 Captiva 5?
It’s mounted on the intake manifold, typically on the top or side where it can sample manifold pressure directly. Look for a small, rectangular sensor with a two- or three-pin connector and a single retaining bolt. On the 2.4L petrol, access is generally from the top of the engine bay without removing major components.

What are common symptoms of a bad MAP sensor on a Captiva 5?
Drivers often notice rough idle, sluggish acceleration, increased fuel use, stalling when coming to a stop, and the check engine light. Scan tools will frequently show codes P0106, P0107 or P0108, and short-term fuel trims may swing rich or lean as the ECU tries to compensate.

Should the MAP sensor be cleaned or just replaced?
If it’s only lightly contaminated with oil mist, a gentle clean with electronics-safe cleaner can restore proper readings. If there’s internal failure, water intrusion, corrosion, or persistent fault codes after cleaning and hose checks, replacement is the better bet. Always renew the O-ring to prevent vacuum leaks.
