2025 Mitsubishi ASX MAP sensor: what it does and how to look after it

Based on OEM technical documentation, a MAP (manifold absolute pressure) sensor is fitted and relevant on the 2025 Mitsubishi ASX. Mitsubishi Motors service information for ASX/Outlander Sport (GA series) details a manifold pressure input used by the engine control module, and the Mitsubishi ASA electronic parts catalogue lists a manifold absolute pressure sensor for ASX applications. For the European 2025 ASX (the Renault Captur–based model), the Renault workshop manual likewise specifies a MAP/T-MAP sensor across the 1.0 TCe/1.3 TCe and E‑Tech hybrid powertrains. Together, these sources confirm the 2025 ASX uses a MAP or combined T‑MAP sensor as part of its engine management.

The MAP sensor measures the absolute pressure inside the intake manifold. The ECU uses that reading to work out engine load, then trims fuel delivery, spark timing and (on turbo or hybrid variants) boost and torque blending. It also helps with altitude compensation and idle quality. On local AU/NZ 2.0‑litre non‑turbo models, it’s a key signal for smooth take‑off, decent fuel economy and consistent kilometres per litre in varied conditions.

Owners will usually notice a crook MAP sensor through a rough idle, flat spots on acceleration, poor fuel use, hard starting or a glowing check‑engine light. Common fault codes include P0106, P0107 and P0108, and sometimes correlation codes with the MAF if that sensor is also fitted.

There’s no fixed replacement interval, it’s a “as needed” item. During routine servicing, it’s smart to:

• Visually check the sensor connector and harness for chafing or corrosion.
• Inspect the O‑ring/seal for cracks or hardening if the sensor is removed.
• Verify live data on a scan tool (kPa tracks barometric pressure KOEO, responds promptly to throttle).

If contamination is suspected, a light mist of electronics contact cleaner on the sensing port can help, but avoid poking the element or soaking it. Oil vapours from the PCV system are the usual culprit, fixing any breather issues prevents repeat fouling. Replacement is straightforward: depressurise the intake, unplug, remove the retaining screw(s), swap the O‑ring, and refit to the specified torque. After reconnecting, a short relearn drive (idle to operating temp, a few gentle accelerations) lets the ECU settle trims.

Note: Some ASX variants use both a MAF and a MAP/T‑MAP. That’s normal—each signal serves a different job, and a mismatch between them is what triggers fault codes.

Popular questions

Does the 2025 Mitsubishi ASX have a MAP or a MAF sensor?

The 2025 ASX includes a MAP (or combined T‑MAP) sensor. Many variants also run a MAF. Turbo and hybrid European models rely heavily on the T‑MAP for load and boost, while AU/NZ 2.0‑litre models use the MAP alongside the MAF for accurate fueling and spark.

What fault codes point to a bad MAP sensor on a 2025 ASX?

Typical MAP‑related DTCs are P0106 (MAP performance/range), P0107 (low input) and P0108 (high input). You might also see correlation codes with the MAF if both are fitted. Always confirm with live data and a smoke test if vacuum leaks are suspected.

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

Light surface contamination can sometimes be cleared with electronics‑safe contact cleaner. Don’t scrape or use harsh solvents. If readings remain erratic, replace the sensor and its O‑ring. There’s no scheduled maintenance interval—service it when symptoms or fault codes appear.
