Parts for your 2021 Suzuki Splash-Throttle position sensors

2021 Suzuki Splash throttle-position-sensors: are they relevant and are they used?

Based on Suzuki model documentation and parts catalogues, a 2021 Suzuki Splash wasn’t produced, so a throttle-position-sensor for a “2021 Suzuki Splash” isn’t applicable. The Splash (also known as Opel Agila B in some markets) ended European production by mid-2014, and the India-market Maruti Suzuki Ritz (the Splash’s twin) was discontinued in 2017. Technical sources such as Suzuki workshop manuals for the K10B/K12B engines, Suzuki’s Electronic Parts Catalogue (EPC), and service information for the Opel Agila B confirm the production timelines and the engine management layout used on actual Splash/Ritz vehicles.

Because the Splash wasn’t built in 2021, a throttle-position-sensor isn’t “used” on that model year simply because that vehicle doesn’t exist. If someone’s rego or listing says “2021 Splash”, it’s almost certainly a data entry error, a later first-registration date for an older build, or a different Suzuki model entirely.

For owners of earlier Splash/Ritz models (2008–2014 in most markets, up to 2017 in India), throttle position sensing is very much a thing. Those cars use electronic throttle control on K10B/K12B petrol engines, with the throttle-position sensor integrated into the throttle body assembly (typically dual-track for redundancy). In practice, that means the sensor usually isn’t sold separately, if it fails or goes out of range (think fault codes like P0120/P0121/P0220), workshops generally replace the complete electronic throttle body and perform an idle/throttle relearn with a scan tool. Regular servicing approach is straightforward: keep the intake tract clean, avoid washing the throttle electronics with harsh solvents, and check live data and fault memory if there’s rough idle, hesitation, or a lit MIL. If cleaning carbon from the throttle plate, use proper throttle cleaner and don’t force the blade on drive-by-wire units. That’s the safest way to keep things sweet and avoid chasing gremlins across kilometres of daily driving.

Does a 2021 Suzuki Splash have a throttle-position-sensor?

No. There wasn’t a 2021 model-year Splash. Earlier Splash/Ritz models (2008–2014 Europe, up to 2017 India) do use throttle-position sensing, typically built into the electronic throttle body.

Where is the throttle-position-sensor on a Suzuki Splash?

On Splash/Ritz models that exist, it’s integrated into the electronic throttle body on the intake manifold. It’s not usually a separate, serviceable sensor, the assembly is replaced as a unit if the sensor fails.

How do you check a Splash throttle-position-sensor if you’re getting hesitation or a MIL?

Scan for DTCs like P0120/P0121/P0220 and compare live data for accelerator pedal and throttle angle. Inspect the intake for air leaks, ensure the throttle body and connector are clean and sound, and only use appropriate cleaners. If the sensor is faulty, the fix is commonly a new throttle body followed by a throttle/idle relearn.
