Parts for your 2007 Holden Commodore-Map sensor

2007 Holden Commodore MAP sensor — what it does, why it matters, and how to look after it

Based on technical sources including the Holden VE Commodore Service Manual (Engine Controls – 6E, DTC P0106/P0107/P0108), GM Global Service Information for 2007 VE/WM models, and parts catalogues from major OEM suppliers (ACDelco and Bosch) that list a manifold absolute pressure (MAP) sensor for both the 3.6L V6 and 6.0L V8, the 2007 Holden Commodore is fitted with and relies on a MAP sensor. It’s a relevant, routinely serviced engine control component on these vehicles.

On a 2007 Commodore, the MAP sensor reads the absolute pressure inside the intake manifold and lets the ECU know how much air the engine is actually pulling. Paired with inputs from the MAF, throttle position and engine speed, it helps the ECU trim fuel, set ignition timing and manage idle quality. That’s why a crook MAP can show up as rough idle, flat spots, higher fuel use and a gutless feel, often with fault codes like P0106, P0107 or P0108.

It’s not a scheduled replacement item, but it’s smart to eyeball it during regular services (for example when doing the air filter). On the VE, the MAP sensor sits on the intake manifold with a small O-ring seal and an electrical connector. Oil mist from crankcase ventilation can sometimes leave residue at the port, a quick check for contamination or a perished O-ring goes a long way.

Tips the workshop likes to follow on a 2007 Commodore MAP sensor:

• Look for split vacuum hoses or manifold leaks first, a vacuum leak can mimic a bad MAP reading.
• If cleaning is needed, use an electronics-safe cleaner sparingly on the port only, don’t poke tools into the sensor.
• If replacing, use quality OEM-equivalent parts and a fresh O-ring. Seat it squarely and tighten the retaining screw to manufacturer spec.
• After refit, clear codes, check fuel trims and take it for a short drive so the ECU can settle. A throttle/idle relearn isn’t usually required, but a scan tool check is good practice.

Signs it’s time to test or replace the MAP on a 2007 Commodore include poor cold start, hunting idle, black smoke, sluggish kickdown, and persistent P0106–P0108 codes. Given how much this little sensor influences drivability and economy, keeping it clean, sealed and talking nicely to the ECU is cheap insurance.

Does a 2007 VE Commodore have both a MAF and a MAP sensor?

Yes. The VE’s ECU uses the MAF for primary airflow measurement and the MAP for manifold load and transient response. If one goes out, the car may still run using fallback strategies, but performance and fuel economy usually suffer until the fault is fixed.

What fault codes point to a dodgy MAP sensor on a 2007 Commodore?

Common ones are P0106 (MAP range/performance), P0107 (low input) and P0108 (high input). Before condemning the sensor, rule out vacuum leaks, wiring issues and a dirty throttle body, as they can all skew manifold pressure readings.

Where is the MAP sensor on the VE, and is it easy to replace?

It’s mounted on the intake manifold (V6 and V8 alike). Access is straightforward with basic tools. Disconnect the connector, remove the retaining screw, lift the sensor, swap the O-ring if needed, and refit. Always clear codes and verify trims after replacement.
