Introduction To MR547077 Mass Air Flow MAF Sensor
The MR547077 is a premium 5-pin drop-in Mass Air Flow (MAF) sensor. It features an integrated intake air temperature (IAT) sensor designed for Mitsubishi applications.
This sensor serves as a direct-fit replacement interchangeable with part numbers MR547077 and 1525A016. It also cross-references codes 197400-2270, 197400-4030, and 197400-6020. It is widely used on renowned 4WD workhorses, including for Mitsubishi L200 / Triton (KB4T 2.5 DI-D) and for Mitsubishi Pajero / Montero / Shogun (V80 / V90 3.2 DI-D 4M41 & 3.8L V6 6G75). It is also compatible with for Mitsubishi Montero Sport / Challenger and for Mitsubishi Grandis.
The MR547077 integrates micro-machined hot-film air-mass metering circuitry. This is paired with an exposed fast-response NTC thermistor. It simultaneously senses intake charge volume and air temperature. The sensor then generates an ultra-precise linear analog output signal (0.5V to 4.5V DC) for the Engine Control Unit (ECU). This critical data allows the engine management system to regulate common-rail diesel injection timing, turbo boost pressure, and EGR rates.
It effectively resolves black exhaust smoke, sudden loss of acceleration, and excessive DPF soot accumulation. It also clears diagnostic trouble codes P0100, P0101, and P0102.

Professional Installation Guidelines
- Safety Preparation: Turn off the engine ignition switch and disconnect the vehicle’s negative battery terminal before servicing electrical components.
- Locate the Sensor: On for Mitsubishi L200, Triton, and Pajero, locate the MR547077 drop-in probe inserted into the air cleaner housing cover or the upper intake duct.
- Disconnect Harness: Depress the center locking tab on the 5-pin electrical connector and carefully pull to disconnect.
- Remove Fasteners: Remove the two retaining screws securing the sensor flange. Gently twist and pull the probe straight out.
- Inspect & Clean Housing: Wipe clean the mounting bore in the air cleaner cover. Ensure the new Viton O-ring is seated in the sensor groove and lightly lubricated.
- Install New Sensor: Insert the new MR547077 probe straight into the mounting hole. Reinstall the two retaining screws and tighten securely (do not over-tighten into plastic).
- Reconnect & ECU Reset: Push the 5-pin harness connector firmly until the lock tab clicks. Reconnect the battery terminal, start the diesel/gasoline engine, allow it to idle for 5–10 minutes to relearn fuel trim parameters, and clear any historical OBD trouble codes using a diagnostic scan tool.
