2016 Holden Commodore MAP sensor — what it does and how to look after it
Based on Holden/GM technical documentation, the 2016 Holden Commodore is fitted with a Manifold Absolute Pressure (MAP) sensor. References include the Holden VF Series II Service Manual (Engine Controls – 3.6L LFX and 6.2L LS3), GM Global Service Information (GSI) procedures for DTCs P0106–P0108, and ACDelco Genuine Parts catalogues listing a MAP sensor for VF/VF Series II Commodore applications. These sources confirm the MAP sensor is used alongside the ECU to calculate engine load and fuelling.
On the 2016 Commodore, the MAP sensor measures the pressure inside the intake manifold so the ECU can gauge how much air the engine is actually drawing. That pressure signal is critical for fuelling, spark timing, idle control, and for catching intake leaks. On the V6 LFX models the MAP sensor works with the Mass Air Flow (MAF) sensor to fine‑tune airmass, on the LS3 V8 it’s equally central to load calculation. If the MAF ever goes out to lunch, the ECU can still run a “speed density” strategy off the MAP reading to keep the Commodore drivable.
There’s no set replacement interval for a MAP sensor, but it pays to add a quick check at service time. A technician will usually:
- Inspect the connector for loose pins, corrosion, or broken locks, and ensure the wiring isn’t chafing on the manifold.
- Confirm the O‑ring seals snugly into the manifold and isn’t cracked or flattened.
- Scan for fault codes like P0106, P0107, or P0108 and compare live MAP kPa against barometric pressure with ignition on, engine off.
- Check for intake leaks that can skew MAP readings and cause rough idle, high fuel use, or a sooty exhaust.
If replacement’s needed, it’s a straightforward job: key off, unplug, release the clip or small bolt, ease the sensor out, lightly lube a new O‑ring with clean engine oil, install, and reconnect. Don’t poke tools into the port or drown the sensor in solvent—contact cleaner is fine for the connector only. Most Commodores don’t need special relearns after a MAP swap, clear codes, then a short drive will let trims settle. For owners chasing smooth idle and decent economy on Aussie or Kiwi roads, keeping that little sensor healthy makes a bigger difference than most expect.
Location notes: on V6 LFX it’s typically on the upper intake near the throttle body, on the LS3 V8 it sits on top at the rear of the manifold. Always confirm by VIN in GM service info.
Popular questions about 2016 Holden Commodore MAP sensors
Where is the MAP sensor on a 2016 Commodore?
On the 3.6L V6 (LFX) it’s mounted on the upper intake plenum near the throttle body. On the 6.2L LS3 V8 it’s usually at the rear top of the intake manifold. Access is generally easy with basic hand tools.
Does the Commodore use both a MAF and a MAP sensor?
Yes, the V6 models use both. The ECU blends MAF and MAP data for accurate airmass. If the MAF fails, the ECU can run on a speed‑density backup using the MAP. The LS3 also relies on the MAP for load sensing.
How often should the MAP sensor be serviced or replaced?
There’s no fixed interval. Inspect the connector and seal at regular services, especially if drivability issues appear. Replace if there are faults like P0106–P0108, contamination, or obvious damage. Clearing codes and a short drive cycle typically finalises the repair.
