Parts for your 2024 Mitsubishi Asx-Map sensor

2024 Mitsubishi ASX MAP sensor: what it does and how to look after it

Yes, a MAP (manifold absolute pressure) sensor is fitted to the 2024 Mitsubishi ASX sold in Australia and New Zealand. This is supported by Mitsubishi workshop manuals for the GA2W-platform ASX 2.0-litre petrol, Mitsubishi parts catalogues that list a “manifold absolute pressure” sensor for the ASX through the 2024 model year, and major aftermarket catalogues (Bosch, NGK/NTK, Delphi, Repco/Supercheap) that specify direct-fit MAP sensors for 2010–2024 ASX 2.0 models. Euro-market ASX (the Renault Captur–based model) also uses a MAP/T‑MAP sensor across its turbo and hybrid engines.

On the 2.0-litre MIVEC petrol, the MAP sensor measures pressure inside the intake manifold. The engine control unit uses this reading (often alongside data from the MAF and intake temperature sensors) to calculate engine load, fuel delivery and ignition timing. A healthy MAP sensor helps the ASX start cleanly, idle smoothly, pull well up hills, and keep fuel use in check.

There’s no scheduled replacement interval for the MAP sensor, it’s a monitor-and-maintain item. At regular servicing, it’s worth checking the electrical connector for corrosion, ensuring the sensor’s O‑ring seals properly, and confirming the harness isn’t chafed. If oil mist or carbon accumulates at the port, a careful clean with electronics-safe cleaner can restore a lazy sensor, but avoid poking the sensing element.

• Common clues of a dodgy MAP: rough idle, flat spots, poor economy, hard starts, higher emissions, and a check engine light (codes like P0106/P0107/P0108).
• Basic swap tips: disconnect the battery, release the plug, remove the retaining fastener(s), lift the sensor straight out, fit a new O‑ring, seat the replacement squarely, and nip the fastener to the workshop spec—don’t over-tighten.

After replacement, a brief idle and gentle drive lets the ECU settle fuel trims. If a fault remains, confirm manifold vacuum integrity and wiring continuity, the issue can mimic vacuum leaks or a failing MAF. Quality branded sensors tend to give the most consistent results, especially on vehicles that see lots of urban stop–start driving.

• Does the 2024 ASX have both a MAF and a MAP sensor?
  Many ANZ-market 2.0-litre ASX models run both. The ECU cross-checks airflow (MAF) against manifold pressure (MAP) to keep fuelling accurate and provide a fallback if one reading drifts. European Captur-based ASX variants typically use a combined T‑MAP on turbo/hybrid engines.
• How often should the MAP sensor be replaced?
  There’s no fixed interval. Replace only if it’s failed testing, throwing relevant fault codes, or causing drivability issues. Otherwise, periodic inspection and keeping the port clean is enough.
• Is it safe to drive with a faulty MAP sensor?
  The car will usually run, but it may be gutless, thirsty, and could trigger limp behaviour. It’s best to diagnose and fix promptly to avoid catalyst damage and unnecessary fuel spend.
