2015 Holden Commodore MAP sensor: purpose, servicing and when to replace

Yes, a MAP sensor is used on the 2015 Holden Commodore. Technical documentation from GM Holden’s VF Service Manual (Engine Controls, GM SI) identifies a Manifold Absolute Pressure (MAP) sensor as an engine control input on the 3.0/3.6‑litre SIDI V6 and the 6.0/6.2‑litre V8 variants. Genuine GM/ACDelco parts catalogues for VF also list a MAP sensor for these engines. Those sources confirm the MAP sensor is fitted and relevant across the VF range.

On the Commodore, the MAP sensor sits on or near the intake manifold and reports intake manifold pressure to the ECU. Alongside the MAF and throttle/oxygen sensors, it helps the ECU calculate engine load, fuelling, and spark, and it steadies things like idle quality, cold starts and tip‑in response. If the MAP data goes missing or out of whack, the car can stumble off the line, drink more petrol, throw a check‑engine light (often with P0106/P0107/P0108), and feel flat through the revs.

While it’s not a scheduled service item, giving the MAP sensor some attention during routine servicing can save headaches down the road. Under the bonnet, a quick visual check for cracked vacuum hoses, brittle connectors, oil mist around the sensor port, or a chafed harness goes a long way. If there’s drivability grief, scan live data—on a healthy Commodore, MAP readings will change smoothly with throttle and match expected kPa at idle and cruise.

If replacement is needed, it’s a simple driveway job for most owners:

• Let the engine cool, disconnect the battery negative, and unplug the sensor connector.
• Release the retaining clip/bolts and lift the old sensor out of the manifold.
• Lightly clean the port (no debris into the manifold), seat the new genuine‑quality sensor, refit fasteners, and reconnect the plug.
• Reconnect the battery, clear any fault codes, and verify readings on a short test drive.

A couple of tips: avoid solvent flushing through the sensor—if it’s oil‑soaked or electrically faulty, replacement is the go. Stick to OE or reputable brands so the ECU sees accurate kPa values. If the car’s had intake work or a vacuum leak, recheck MAP data and fuel trims once everything’s buttoned up.

Done right, the Commodore’s MAP sensor quietly keeps the tune crisp, the idle smooth, and the fuel bill reasonable—just the way local owners like it.

Popular questions

Where is the MAP sensor on a 2015 Holden Commodore?
It’s mounted on the intake manifold. On V6 models it’s typically on the upper manifold/plenum area, on V8s it’s on the manifold body near the rear or centre, depending on engine. It has a small electrical connector and sits in a port that sees manifold vacuum/pressure.

If you’re unsure, follow the intake from the throttle body to the manifold and look for a small, clip‑in sensor with a two‑ or three‑pin connector.

What are the signs a MAP sensor is failing on a VF Commodore?
Common clues include a check‑engine light, rough idle, sluggish acceleration, poor fuel economy, hard starts, and inconsistent throttle response. Scan tools may show MAP‑related fault codes or jumpy, implausible kPa readings that don’t match throttle position or RPM.

Because vacuum leaks can mimic MAP faults, it’s smart to smoke‑test or inspect hoses and gaskets before buying parts.

Should a MAP sensor be cleaned or just replaced?
If the sensor tip has light oil mist, a gentle wipe and careful port clean may help. If it’s contaminated internally, gives erratic readings, or sets recurring codes, replacement is the reliable fix. MAP sensors aren’t expensive and swapping one is quick with basic tools.

When replacing, choose OE or quality aftermarket to keep fuelling and timing calculations spot‑on.
