Parts for your 2024 Mitsubishi Asx-Maf sensor

2024 Mitsubishi ASX MAF Sensor

Based on Mitsubishi service literature for the 4B11 2.0‑litre petrol used in the 2024 ASX (Group 13A – Fuel/Engine Control) and the Mitsubishi ASA electronic parts catalogue for ASX (GG/GK series), this model is fitted with a hot‑film Mass Air Flow (MAF) sensor on the air cleaner outlet duct. Major aftermarket catalogues (Denso and NGK/NTK) also list a direct‑fit MAF for 2010–2024 ASX 2.0L, supporting its use on current AU/NZ vehicles.

The 2024 Mitsubishi ASX relies on a MAF sensor to precisely measure the mass of air entering the engine, letting the ECU trim fuel and ignition so it runs clean, smooth and sparky under the bonnet. By constantly reporting airflow, it helps the 2.0‑litre MIVEC deliver decent economy around town and steady torque on the motorway, while keeping emissions in check.

When a MAF starts to go off, the ASX can feel doughy or hesitant on take‑off, idle a bit rough, or sip more petrol than usual. It can also throw a check‑engine light with codes like P0100–P0104. Because the sensing element is delicate, the first step is always inspection and a careful clean rather than diving straight to replacement.

As part of regular servicing, it’s worth giving the MAF some attention every 20,000–30,000 km (or sooner if the ASX sees dusty roads):

• Use a proper MAF‑safe cleaner only, avoid brake/carb sprays that can leave residue.
• Don’t touch the hot‑film element with fingers or tools.
• Check the airbox seal, intake duct clamps and PCV hoses for leaks that skew readings.
• Avoid over‑oiled aftermarket filters, which can contaminate the sensor.

If cleaning doesn’t restore smooth running, a quality replacement is the go. Stick with genuine Mitsubishi or a reputable brand that matches the OE calibration and connector. Replacement is straightforward: disconnect the battery (protects electronics and can help a quick relearn), unplug the connector, swap the sensor, and ensure the O‑ring seats properly. After refit, let the engine idle for a few minutes, then take a gentle drive so the ECU can adapt. If a light remains, scan and clear any codes and check for unmetered air leaks.

Looked after, the ASX’s MAF works quietly in the background, keeping fuel trims tidy and drivability crisp for the long haul.

Popular questions

Where is the MAF sensor on a 2024 Mitsubishi ASX?
It’s mounted in the intake duct just downstream of the air filter box. Pop the bonnet and follow the airbox outlet towards the throttle body—you’ll spot the small sensor housing with an electrical plug.

This position lets it measure all incoming air before it reaches the throttle, giving the ECU the most accurate airflow data.

Can a dirty MAF cause high fuel use on an ASX?
Yes. Contamination makes the sensor under‑ or over‑report airflow, so the ECU adds too much fuel. Drivers often notice more frequent fills, a lazier throttle response, or a check‑engine light.

A careful clean with a dedicated MAF cleaner often restores proper readings and trims fuel use back to normal.

How often should the MAF be cleaned?
For typical AU/NZ driving, every 20,000–30,000 km is a sensible interval. If the ASX regularly sees gravel roads or coastal air, inspect and clean it more frequently.

Always ensure the airbox is sealed and the filter is in good nick—preventing dust and oil vapour from reaching the sensor is half the battle.
