Parts for your 2012 Mitsubishi Outlander-Map sensor

2012 Mitsubishi Outlander MAP Sensor — what it does and how to look after it

Based on Mitsubishi’s factory literature and parts catalogues, a MAP sensor is used on the 2012 Outlander. The Mitsubishi Outlander 2012 Service Manual (engine electrical/ECU inputs) details a Manifold Absolute Pressure sensor for the petrol 4B12 2.4 and V6 6B31 engines, and a boost/MAP sensor for the 2.2 Di-D (4N14) diesel. Mitsubishi ASA parts listings for CW-series Outlander models also show a “sensor, manifold absolute pressure” fitted across these variants, and independent repair databases (e.g., Autodata/AllData) document related diagnostics (P0106–P0108). So yes—this model does run a MAP sensor, and it matters.

The MAP sensor tells the ECU how much pressure is in the intake manifold, which the ECU blends with throttle angle, engine speed and intake air temperature to calculate load. On the petrol Outlander it works alongside the MAF to keep fuelling and ignition tidy, on the diesel it measures boost and helps manage EGR and DPF strategies. When it’s healthy, you get smooth idle, decent fuel economy, and solid take-off without that doughy hesitation.

There’s no set replacement interval—think of it as “inspect and clean if needed.” Common clues it’s grumpy include:

• Sluggish acceleration, higher-than-usual fuel use, or a rough idle
• Check-engine light with P0106, P0107 or P0108
• Black smoke on diesels or an off-smell from the exhaust

Basic care is easy under the bonnet:

1. Ignition off. Find the sensor: on petrol models it’s bolted to the intake manifold near the throttle, on diesels it’s on the manifold/intercooler outlet reading boost.
2. Unplug the connector and remove the fixing screws. Note the O-ring—replace if flattened or torn.
3. If dirty, mist the tip with electronics-safe MAF/MAP cleaner. Don’t poke the diaphragm or use compressed air up close.
4. Refit, nip the screws to workshop spec, reconnect and clear any codes.

A sensor that’s oil-soaked, cracked, or repeatedly sets pressure range codes is best replaced rather than endlessly cleaned. Always check for split vacuum hoses (where fitted), loose intake clamps, or soot build-up on diesels—those can mimic a bad MAP reading. After replacement, a quick test drive and a live-data check (kPa tracking barometric at key-on, then responding smoothly with throttle) will confirm the fix.

FAQs

Does a 2012 Mitsubishi Outlander have a MAP or just a MAF?
It has both on the petrol models: a MAF in the airbox ducting and a MAP on the manifold. The diesel uses a MAP/boost sensor on the intake to manage turbo pressure and EGR. This layout is confirmed in Mitsubishi’s 2012 service information and parts listings for CW-series Outlanders.

Where is the MAP sensor located on a 2012 Outlander?
Petrol 2.4 and V6: bolted to the intake manifold near the throttle body, with a small O-ring seal. Diesel 2.2: mounted to the intake/charge pipe or manifold where it can read boost pressure. It’s a small rectangular sensor with a 3-pin plug.

Can a dirty MAP sensor be cleaned, or should it be replaced?
Light contamination can be cleaned with electronics-safe sensor cleaner. If it’s oil-soaked, physically damaged, or keeps throwing range/performance codes after a clean and hose check, replacement is the better bet. Always inspect hoses and clamps first, as leaks skew readings.
