Parts for your 2007 Mitsubishi Outlander-Map sensor

2007 Mitsubishi Outlander MAP sensor – what it does, where it fits, and when to replace it

Relevant or not? According to Mitsubishi technical information, the 2007 Outlander’s need for a MAP (manifold absolute pressure) sensor depends on the engine. The 3.0‑litre V6 (engine code 6B31, CW6W/ZG‑ZH) uses a MAP sensor mounted on the intake manifold for speed‑density load calculation. The 2.4‑litre four‑cylinder (engine code 4B12, CW5W/ZG‑ZH) primarily uses a MAF (mass air flow) sensor and does not rely on a separate MAP sensor for normal operation. This is documented in the Mitsubishi Outlander 2007 Workshop Manual, Engine Electrical (Group 13A), and confirmed by the Mitsubishi ASA Electronic Parts Catalogue for CW6W/CW5W models.

For Outlander models fitted with a MAP sensor (notably the 3.0 V6), the part’s job is simple but crucial: it reads the absolute pressure in the intake manifold and tells the ECU how hard the engine’s working. With that signal, the ECU trims fuel delivery and ignition timing to keep performance crisp, fuel economy tidy, and emissions in check. It also helps with smooth idle, clean take‑offs, and consistent shift quality in autos.

Owners will often notice a tired or faulty MAP sensor through a handful of tell‑tales: lazy acceleration, rough idle, stalling at lights, thirsty fuel use, and the check‑engine lamp. Common fault codes include P0106 (MAP range/performance), P0107 (low input), and P0108 (high input), sometimes alongside mixture codes like P0171/P0172.

On the 6B31 V6, the MAP sensor is typically perched on the upper intake manifold near the throttle body, using a 3‑pin connector and sealed with an O‑ring. It’s not a regular “replace on schedule” item, but it’s smart to check it at major services (say, every 60,000 km) or whenever drivability turns average.

• Visual checks: look for cracked wiring, loose plugs, or perished O‑rings.
• Cleaning: if contamination is suspected, use electronics‑safe cleaner sparingly, don’t drown the sensor.
• Vacuum integrity: ensure no manifold leaks that can throw readings out.
• Refit: seat the O‑ring squarely and nip fasteners evenly, clear any stored codes and road‑test.

If replacement’s needed, go for quality OEM‑grade sensors (calibration matters). After fitment, clearing codes and letting the ECU relearn trims (a short mixed‑route drive) helps restore tip‑top behaviour. For 2.4‑litre owners chasing similar symptoms, attention should turn to the MAF sensor and intake leaks rather than a MAP sensor, as the MAP isn’t part of the normal load‑sensing strategy on that engine.

Technical basis: Mitsubishi Outlander 2007 Workshop Manual, Engine Electrical/ECU Inputs (Group 13A), Mitsubishi ASA Electronic Parts Catalogue (CW6W 6B31 lists “Sensor, Manifold Absolute Pressure”, CW5W 4B12 lists “Mass Air Flow Sensor”).

Popular questions

Does my 2007 Outlander have a MAP or a MAF sensor?

The 3.0‑litre V6 uses a MAP sensor on the intake manifold and does not use a MAF. The 2.4‑litre four‑cylinder uses a MAF in the intake ducting and typically doesn’t have a separate MAP for load sensing. Check your engine code: 6B31 (V6) = MAP, 4B12 (2.4) = MAF.

What fault codes point to a bad MAP sensor on the V6?

Common ones are P0106 (range/performance), P0107 (low input) and P0108 (high input). You might also see mixture codes like P0171 or P0172 if the readings throw fuelling off. Always rule out vacuum leaks and wiring faults before condemning the sensor.

Can a dirty throttle body or vacuum leak mimic a MAP fault?

Absolutely. A sticky throttle plate or a split hose can cause unstable manifold pressure and trigger MAP‑style symptoms or codes. Cleaning the throttle body and smoke‑testing for leaks are smart first steps before replacing parts.
