BRAND NEW *OEM Quality* mass airflow sensor to suit Mitsubishi Triton and Pajero with the 4D56, 4D56-T and 4D56-HP diesel engines.

The 4D56 is notorious for MAF sensor issues - a failing sensor causes black smoke, sluggish performance and rough idle, often accompanied by a P0100-series fault code. This BRAND NEW direct-fit replacement restores correct air metering and ECU fuelling on the 4D56 without any wiring modification. Packed and shipped from Cranbourne VIC with same-day dispatch.

TO SUIT

This sensor suits the Mitsubishi Triton K-series and KA/KB series with the 2.5L 4D56 and 4D56-T diesel engines (1986-2015), including the Pajero and Challenger with the same engine family fitted with an intercooler. Covers both the earlier SOHC 8-valve and later DOHC 16-valve 4D56-HP variants. See full vehicle list above.

FITMENT CHECK

This sensor suits Triton and Pajero models fitted with an intercooler. Normally-aspirated diesel variants use a different sensor. Confirm your vehicle is turbocharged before ordering.

ABOUT THIS SENSOR

The MAF sensor on the intercooled 4D56 diesel measures intake air volume post-intercooler so the ECU can control fuel injection quantity and boost pressure together. The sensor operates at 12V with a bolted mounting and an integrated temperature element.

When the sensor fails on a turbocharged 4D56 the ECU defaults to a conservative fuel map, causing black smoke, sluggish throttle response and poor towing performance.

COMMON SYMPTOMS OF FAILURE

Check engine light with codes P0100-P0103
Heavy black smoke under acceleration
Sluggish throttle response and poor towing performance
Rough idle or hunting at operating temperature
Increased fuel consumption
Limp mode or reduced power on later KA/KB models

Can I clean my MAF sensor instead of replacing it?

Yes - if the sensor is contaminated rather than electrically failed, cleaning with a dedicated MAF sensor cleaner spray can restore correct readings. Do not use brake cleaner or generic electrical contact cleaner as these leave residue that damages the sensing wire. Allow the sensor to dry completely before reinstalling. If cleaning does not resolve the fault codes, the sensor requires replacement.

What is the difference between a MAF sensor and a MAP sensor?

A MAF (Mass Air Flow) sensor directly measures the mass of air entering the engine using a hot wire element in the intake. A MAP (Manifold Absolute Pressure) sensor measures intake manifold pressure to calculate air density. Most modern engines use one or the other - some use both. Your vehicle service manual or OBD2 fault codes will confirm which sensor type your engine uses.

Will a faulty MAF sensor cause my vehicle to fail an emissions test?

Yes. A faulty MAF sensor causes the ECU to miscalculate fuel delivery, typically resulting in a rich running condition that increases CO and hydrocarbon emissions. Most roadworthy and emissions checks will fail a vehicle with an active MAF sensor fault code or visibly excessive exhaust smoke.

What are the symptoms of a bad MAF sensor?

Common symptoms include rough idle, hesitation or stumbling on acceleration, poor fuel economy, black smoke from the exhaust, and an illuminated Check Engine light. Your ECU may log fault codes P0100 to P0104.

Can I drive with a faulty MAF sensor?

You can drive short distances but it is not recommended. A faulty MAF sensor causes the ECU to run incorrect fuel mixtures, which can damage the catalytic converter and O2 sensors over time. Have it replaced as soon as possible.

How do I test if my MAF sensor is bad?

Use an OBD2 scanner to check for fault codes P0100-P0104. You can also use a multimeter or live data scanner to check the sensor output voltage against your vehicle's specification. A reading significantly outside spec confirms a faulty sensor.

What causes a MAF sensor to fail?

The most common causes are a dirty or contaminated sensing element (often from a missing or damaged air filter), oil contamination from an over-oiled aftermarket air filter, heat damage, or general wear over time.

Do I need to reset my ECU after replacing the MAF sensor?

It is good practice to clear any stored fault codes using an OBD2 scanner after replacement. Some vehicles will self-adapt within a short drive cycle, but clearing codes ensures the ECU recalibrates from a clean baseline.
