Parts for your 2016 Subaru Exiga-Map sensor

2016 Subaru Exiga MAP sensor

Yes—the 2016 Subaru Exiga is fitted with a MAP (Manifold Absolute Pressure) sensor. Technical references that confirm this include Subaru’s Factory Service Manual for the Exiga YA series (Engine/OBD diagnostics listing DTCs P0105–P0108 for the Manifold Absolute Pressure circuit) and Subaru’s FAST electronic parts catalogue, which lists a “manifold absolute pressure/pressure sensor” for 2016 Exiga variants. Subaru commonly uses both MAF and MAP sensing across FB- and EJ-series engines, including Exiga models of this era.

On the 2016 Exiga, the MAP sensor feeds the ECU real-time intake manifold pressure so the engine can calculate load accurately. That helps it trim fuelling and ignition timing for smooth performance, good economy, and clean emissions. On turbo variants, it’s also key for boost control and knock prevention, on naturally aspirated versions it assists transient response, altitude compensation, and serves as a fallback if the MAF reading goes wonky.

Location-wise, owners will typically find the MAP sensor mounted on or near the intake manifold. Some EJ turbo layouts use a short vacuum hose to a remotely mounted pressure sensor, while FB engines usually have the sensor bolted directly to the manifold near the throttle body. Either way, it’s an easy reach under the bonnet with basic hand tools.

Signs the MAP sensor’s having a bad day include:

• Sluggish take-off, rough idle, or stalling after starts
• Heavier-than-normal fuel use and sooty tailpipe
• Check Engine Light with codes like P0106, P0107, or P0108

As part of regular servicing, a quick MAP sensor check pays off. Make sure the connector is snug and clean, inspect any vacuum hose for splits or oil soak, and confirm the sensor port isn’t clogged with carbon or oil mist. If cleaning is needed, use a plastic-safe electronics/contact cleaner—go easy, don’t soak it, and never poke the sensing element. Avoid generic carb cleaners that can attack plastics.

If replacement’s on the cards, choose a quality OE or reputable aftermarket unit. Swap is typically a 10–20 minute job: disconnect the battery if you like to be cautious, unplug the connector, remove the fasteners, transfer the O-ring if applicable, and refit. Nip the small bolts to the factory spec from the service manual—no gorilla torque. After installation, clear fault codes and let the ECU relearn with a short mixed drive. Keeping the MAP sensor healthy helps the Exiga run crisply, saves fuel on long Kiwi and Aussie road trips, and protects the catalytic converter from over-fuelling.

Does the 2016 Subaru Exiga have both a MAF and a MAP sensor?

Yes. Subaru calibrations of this era commonly use a MAF for primary airflow measurement and a MAP for manifold pressure/load modelling, transient response, altitude compensation, and diagnostics. That dual-sensor strategy improves drivability and reliability.

How often should the MAP sensor be checked or cleaned?

Give it a look every 20,000–30,000 kilometres or at major services. Only clean it if you see signs of contamination or you’re chasing related fault codes. Always inspect the connector and any vacuum hose at the same time.

Is it safe to drive with a faulty MAP sensor?

The engine will usually run, but it may default to a backup strategy with poor fuel economy, flat spots, and a glowing MIL. Prolonged use can risk over-fuelling and damage to the catalytic converter. Best to diagnose and fix it promptly.
