2014 Mitsubishi ASX MAP Sensor — What it does and how to look after it

Technical sources confirm the 2014 Mitsubishi ASX is fitted with a MAP (Manifold Absolute Pressure) sensor. The Mitsubishi Motors Workshop Manual for ASX/RVR/Outlander Sport (2010–2015), Engine and Emissions Control sections, details MAP sensor operation and diagnostics, and the Mitsubishi ASA electronic parts catalogue lists a manifold pressure sensor across both 2.0L petrol (4B11) and diesel variants. Independent databases such as Autodata/HaynesPro also specify MAP-sensor test values and fault code references (P0106–P0108) for this model year.

On a 2014 Mitsubishi ASX, the MAP sensor reads the absolute pressure inside the intake manifold so the ECU can work out air density and engine load. That lets the car trim fuel delivery, spark timing and, on diesels, control boost and EGR. It also helps with altitude compensation and keeps idle quality tidy. Even on petrol models that use a MAF, the MAP is used for transient load accuracy and as a backup strategy if the MAF reading goes off.

It’s not usually a scheduled service item, but a quick check under the bonnet during regular servicing pays off. Look for oil mist or soot on the sensor tip, cracked O-rings and brittle wiring. If it’s a bit grubby, remove it and clean the tip with an electronics-safe cleaner (avoid harsh carb/brake cleaners). Don’t poke the sensing element. Refit with a light smear of clean engine oil on the O-ring and torque the fixing bolts snug (around 8–10 N·m is typical, check the manual for your exact engine).

• Common symptoms of a failing MAP: lazy throttle response, higher fuel use, rough idle, black smoke on diesel, limp mode, and a check-engine light (P0106, P0107, P0108).
• If a code keeps returning after cleaning, replacement with a quality OE-equivalent sensor is the go.

Replacement is straightforward on most ASX engines: disconnect the battery, unplug the connector, remove the retaining screw(s), lift the sensor, swap the O-ring, and refit. After replacement, clear codes and perform an idle relearn if your scan tool supports it, then road-test to verify boost and load values look normal on live data.

For diesel ASX owners, add a quick check of the intercooler and MAP passage for oil build-up, and make sure the EGR system isn’t loading the manifold with soot that’ll foul the MAP again.

Popular questions about the 2014 Mitsubishi ASX MAP sensor

Where is the MAP sensor on a 2014 Mitsubishi ASX?
On the 2.0L petrol engine it’s mounted on or near the intake manifold, facing the plenum with a two- or three-pin connector. Diesel models position it on the intake manifold or charge pipe so the ECU can read boost. It’s accessible from the top once the engine cover is off.

Can you drive with a bad MAP sensor?
It’ll usually still run, but it may chew more fuel, feel flat, and on diesel models may smoke or go into limp mode. Prolonged driving with a faulty MAP can stress the DPF (diesel) or catalyst (petrol). Best bet is to diagnose, clean, and replace if readings are out of spec.

What are the typical fault codes for a MAP issue?
The common ones are P0106 (MAP range/performance), P0107 (low input), and P0108 (high input). You might also see mixture or EGR-related codes because dodgy pressure data throws off fuelling and gas flow calculations.
