2017 Holden Commodore MAP sensor — purpose, servicing and replacement

Yes, a MAP sensor is relevant and fitted to the 2017 Holden Commodore (VF Series II). Technical sources including the Holden VF Commodore Service Manual (Engine Controls for both the 3.6‑litre SIDI V6 and the 6.0/6.2‑litre V8), GM Service Information “MAP Sensor — Description and Operation”, and parts catalogues from major suppliers (e.g., ACDelco and Tridon) all list a manifold absolute pressure sensor for these engines. The V6 models use the MAP alongside a MAF, while the V8 relies on the MAP as a primary load input.

The MAP sensor measures the absolute pressure inside the intake manifold. The engine control module uses that pressure, intake air temperature and engine speed to work out how much air is going in, then trims fuel, spark timing and EGR/EVAP behaviour to suit. On the VF V6 it also cross‑checks the MAF reading, helping the car cope with rapid throttle changes and altitude. The result is smoother idle, better throttle response and reliable cold and hot starts.

On VF models the MAP sensor sits on the intake manifold (typically top or rear section near the throttle body), sealed by an O‑ring and connected with a three‑pin plug. It’s a solid‑state part with no scheduled replacement interval, but it appreciates a clean, dry connector and an intact seal so it reads true manifold pressure without leaks.

• Common signs of a dodgy MAP: sluggish take‑off, rough idle, hard starting, higher fuel use, black smoke on rich running, and a check‑engine light (codes like P0106, P0107, P0108 or correlation faults such as P0068).
• Simple care: keep the electrical connector clean and clipped firmly, and make sure the O‑ring isn’t flattened or split. Avoid soaking the sensing port with solvent or carby cleaner.

When replacement is needed, choose an OE‑equivalent sensor and a fresh O‑ring. With the engine off, unplug the connector, undo the retaining screw, lift the sensor out, lightly oil the new O‑ring, seat it squarely and refit the screw to snug (not gorilla‑tight). Plug back in, clear any codes, then let the engine idle for a few minutes and take a short drive so the ECM can settle trims. If the vehicle has been tuned or modified, ensure the calibration matches the sensor’s range. It’s also smart to check nearby hoses and the manifold for vacuum leaks at the same time—no point asking a brand‑new sensor to report through a leak.

Where is the MAP sensor on a 2017 Holden Commodore?

It’s mounted on the intake manifold. On the V6 it’s typically near the rear/top of the plenum, on the V8 it’s close to the throttle body area on the manifold. Look for a small, black, three‑pin sensor clipped in with a single screw and sealed by an O‑ring.

Can a MAP sensor be cleaned, or should it just be replaced?

If it’s only dusty, a gentle air blow‑off and a wipe of the connector is fine. Avoid flooding the sensing port with harsh cleaners. If it’s oil‑soaked, cracked, or throwing repeat codes after checks for vacuum leaks and wiring, replacement is the reliable fix.

What fault codes point to a MAP sensor issue on a VF Commodore?

Common ones are P0106 (range/performance), P0107 (low input), P0108 (high input) and sometimes P0068 (MAP/MAF correlation). Confirm power/ground integrity, check the connector and O‑ring, and rule out manifold or hose leaks before condemning the sensor.
