Parts for your 2021 Suzuki Splash-Maf sensor

2021 Suzuki Splash MAF sensor — is it there or not?

Short answer: a 2021 Suzuki Splash doesn’t use a MAF (mass air flow) sensor. Suzuki set the Splash up with a speed‑density system, which measures intake air using a MAP (manifold absolute pressure) sensor and an intake air temperature sensor, then the ECU calculates airflow. That means there’s no hot‑wire MAF in the airbox on this model.

This isn’t guesswork. Technical references including the Suzuki Splash/Swift K‑series workshop literature (Engine Control System section), Maruti Suzuki Ritz (the Indian‑market Splash twin) K12 service manual, and Suzuki’s Electronic Parts Catalogue list a MAP sensor for the K10/K12 engines and do not list a MAF. Bosch engine‑management documentation also explains why small‑displacement engines commonly run speed‑density: fewer parts, robust operation in dusty conditions, and simpler packaging.

Why skip the MAF on the Splash? MAP‑based systems suit the compact intake layout and stable volumetric efficiency of the K‑series engines. They’re cheaper, less fragile, and less sensitive to airbox or snorkel changes. For Aussie and Kiwi owners, that also means fewer headaches after a filter or intake duct swap.

What should a driver or tech look for instead? There’ll be no sensor sitting in the airbox outlet. Instead, a small MAP sensor bolts to the intake manifold (or connects via a short vacuum port) with a 3‑pin plug. Intake air temperature is read separately (location varies by engine code and market—either in the manifold or intake duct). The ECU blends MAP, IAT, throttle position, and O2 feedback to nail fuelling.

• Chasing rough idle or dodgy fuel trims on a Splash? Think MAP, vacuum leaks, or gunked throttle body—don’t go hunting for a MAF that isn’t fitted.
• If a scan tool shows airflow‑related faults, typical MAP codes are P0106–P0108. Clean the throttle body, check PCV and breather hoses, ensure the MAP port isn’t blocked, and verify IAT readings before condemning parts.
• Aftermarket listings that say “MAF” for Splash often mean the MAP—double‑check the part description and connector.

Bottom line: for a 2021‑registered Splash, the factory setup is MAP‑based. Service the intake tract, keep vacuum plumbing tight, and the little Suzuki will be happy without a MAF ever entering the picture.

Popular questions

Does a 2021 Suzuki Splash have a MAF sensor?
No. The Splash uses a MAP sensor and intake air temperature sensor to calculate airflow. Suzuki’s service manuals and parts listings for K10/K12 engines show no MAF on this platform.

What actually measures the intake air on a 2021 Splash, and where is it?
A MAP sensor on the intake manifold reads pressure, and an IAT sensor reads air temperature (location varies by engine code—manifold or intake duct). The ECU combines these with throttle and O2 inputs to set fuelling.

My scanner shows a “MAF” code—what now?
Some generic tools label airflow faults as MAF even on MAP systems. On a Splash, look for MAP‑related faults (P0106–P0108), vacuum leaks, a blocked MAP port, or incorrect IAT values before replacing anything.
