Parts for your 2023 Suzuki Splash-Maf sensor

2023 Suzuki Splash MAF sensor — used or not?

Short answer: a MAF sensor isn’t used on a 2023 Suzuki Splash. The Splash nameplate ended global production years earlier, and the petrol Splash models (K10B 1.0 and K12B 1.2) use a MAP-based (speed–density) system rather than a hot-film MAF. Only the older 1.3 DDiS diesel variant was equipped with a MAF on the air intake. So for any late-registered or imported “2023” Splash in Australia or New Zealand, if it’s petrol, there’s no MAF to service.

Why no MAF on the petrol Splash? Suzuki’s engine management for the K-series engines calculates air mass from manifold absolute pressure, intake air temperature and engine speed. That approach is robust, cost-effective, and well suited to small-capacity engines. It trims parts count under the bonnet, avoids a delicate hot-wire element, and is less fussy about minor intake changes. The ECM strategy still meets emissions and drivability targets without the added complexity of a dedicated airflow meter.

Technical references that support this: Suzuki Splash service documentation for K10B/K12B details a MAP sensor and IAT input with speed–density fuelling, and the Suzuki parts catalogue lists a MAP sensor for petrol variants but does not list an airflow meter. Conversely, documentation covering the 1.3 DDiS (Fiat Multijet with Bosch EDC) specifies a hot-film MAF in the intake tract. That’s why owners of diesel Splashes will find a MAF, while petrol owners won’t.

What does this mean for servicing a “2023” Splash? For petrol cars, maintenance focuses on the MAP sensor and the intake path: keep the air filter fresh, ensure there are no vacuum leaks or split hoses, and avoid over-oiled aftermarket filters that can contaminate the MAP or throttle body. If there are symptoms that feel like a dodgy MAF—rough idle, flat spots, high fuel use—on a petrol Splash the usual culprits are a dirty throttle body, a compromised MAP sensor port, intake leaks, or ageing O2 sensors, not a failed MAF.

Popular questions

Does a 2023 Suzuki Splash have a MAF sensor?
For petrol versions, no. They use a MAP sensor and speed–density fuelling. Only the older 1.3 DDiS diesel Splash used a MAF on the intake, and the Splash wasn’t produced new in 2023.

Where is the MAP sensor on a Suzuki Splash?
On petrol models, the MAP sensor is mounted on or near the intake manifold with a direct port to manifold vacuum. It’s typically held by a small bracket or bolts and connects via a multi-pin plug.

What symptoms mimic a bad MAF on a petrol Splash?
Rough idle, hesitation and poor fuel economy can come from a dirty throttle body, clogged or contaminated MAP sensor port, vacuum leaks, or tired oxygen sensors—rather than a MAF, which the petrol Splash doesn’t have.
