Parts for your 2017 Mitsubishi Outlander-Map sensor

2017 Mitsubishi Outlander MAP sensor — what it does and how to look after it

Yes, the 2017 Mitsubishi Outlander uses a MAP (Manifold Absolute Pressure) sensor. Technical documentation including the Mitsubishi Outlander Workshop Manual (Engine Control – “Manifold Absolute Pressure Sensor”), Mitsubishi ASA/parts catalogue listings for 2015–2018 Outlander (engines 4B11/4B12 2.0–2.4 petrol, 6B31 3.0 V6, 4N14 2.2 diesel, and PHEV variants), and independent service databases like Autodata/Mitchell confirm a dedicated MAP or boost pressure sensor is fitted across these powertrains.

The MAP sensor’s job is to read absolute pressure inside the intake manifold so the ECU can work out engine load. That data helps fine‑tune fuel delivery, ignition timing, EGR operation and, on the diesel, turbo boost control. On the Outlander PHEV and petrol models, it keeps drivability tidy when transitioning between light throttle and heavier acceleration, on the 2.2 diesel it’s critical for boost and smoke control. Some models also run a MAF sensor up-stream — the MAP doesn’t replace it, they simply work together for accuracy.

It’s not a scheduled replacement item, but it does benefit from a bit of care. Under the bonnet, check the MAP sensor’s electrical connector for corrosion or loose terminals, make sure the harness isn’t rubbing through, and confirm the sensor’s O‑ring/seal is sound. If your variant uses a short vacuum gallery or hose to the sensor, ensure there are no splits or oil blockage. If cleaning is needed, use electronics-safe MAF/MAP cleaner only — don’t poke the port with anything sharp.

• Common clues it’s playing up: rough idle, flat spots, hard starts, poor fuel economy, diesel soot, or the check engine light with codes like P0106, P0107 or P0108.
• Replacement tips: verify with live data and vacuum/pressure tests first. Fit a quality OEM-spec sensor, lightly lubricate the O‑ring, torque to spec, reconnect the battery, clear codes and perform an idle relearn/road test. Avoid cheap knock-offs that skew readings by a few kPa — that’s enough to upset fuel trims.

For Outlander owners in Australia and New Zealand, a healthy MAP sensor helps keep emissions in check and fuel use sensible on long kilometres. If symptoms appear, don’t wait — a quick diagnosis can save a DPF headache on the diesel and keep the family SUV feeling crisp around town.

• Popular questions about 2017 Mitsubishi Outlander MAP sensors

Where is the MAP sensor on a 2017 Outlander?
On most petrol variants it’s mounted on or near the intake manifold plenum, secured with a small bolt and an O‑ring seal. The 2.2 diesel uses a boost pressure sensor on the intercooler pipework or manifold, serving the same MAP role. It has a three‑pin connector.

Can a dirty MAP sensor cause high fuel use?
Absolutely. If it reads low pressure (thinks there’s less air), the ECU can over‑fuel, hurting economy and making the engine feel doughy. A careful clean and checking for vacuum leaks usually sorts it, otherwise replacement is straightforward.

Do I need to replace the MAP sensor as part of regular servicing?
No routine interval is specified in Mitsubishi service schedules. Inspect it during services, clean if contaminated, and only replace if fault codes or testing confirm it’s out of range or sluggish.
