Parts for your 2022 Suzuki Splash-Knock sensor

Is a knock sensor used on the 2022 Suzuki Splash?

Short answer: a knock sensor isn’t relevant to a 2022 Suzuki Splash because there wasn’t a 2022 Splash. The Splash (also sold as the Maruti Ritz in India) ended production years earlier, so any 2022-model listing is a catalogue or SEO artefact rather than a real vehicle application.

Technical sources that detail the Splash’s lifecycle and engine control hardware point to two things: 1) the Splash wasn’t made in 2022, and 2) earlier Splash engines did use a knock sensor. Collectively, factory manuals and parts catalogues confirm this.

• Suzuki Splash/RS415 factory service information (Engine Control System): documents a knock/detonation sensor in the K10B and K12B petrol engine management.
• Maruti Suzuki Ritz (Splash) service manual: shows knock-sensor input used by the ECU for ignition timing on petrol variants.
• Suzuki electronic parts catalogues (EU/UK, RS415, 2008–2014): list a detonation/knock sensor for petrol models, model history shows end of production mid‑2010s.

Why a knock sensor isn’t used on the “2022 Splash”: because that model year doesn’t exist. The Splash line wrapped up in the mid‑2010s (Europe around 2014, the Indian-market Ritz followed later), so there’s no 2022 vehicle for a knock sensor to be fitted to. Online parts directories sometimes auto-generate late model years or merge trim lines, which is how “2022” crops up.

If someone actually owns a Splash from its real production years, that car almost certainly has a knock sensor (petrol K10B/K12B, and the DDiS diesel uses its own knock/combustion sensing strategy). For those genuine cars, the knock sensor lets the ECU detect pinging and trim ignition timing to protect the engine and keep it sweet on Aussie and Kiwi fuels. If a Splash throws a knock-sensor fault, check the basics first: correct octane, no vacuum leaks, sound engine earths, and clean connector pins. Replacement is typically straightforward but access can be tight under the intake manifold—use the correct torque on the new sensor and route the harness exactly as per the manual to avoid false readings from vibration.

Bottom line: for a “2022 Suzuki Splash”, a knock sensor listing isn’t applicable. For earlier Splash models, yes, the part exists and does important work keeping the engine safe and efficient.

• Does a 2022 Suzuki Splash exist in Australia or New Zealand?
  No. The Splash finished up years earlier. You might see late registrations, but those are older build years first sold or registered later. Any 2022 parts listing for “Splash” is not a true model-year fitment.
• Do earlier Suzuki Splash models have a knock sensor?
  Yes, petrol Splash engines (K10B/K12B) use a knock/detonation sensor that feeds the ECU for spark control. It’s a normal bit of modern engine management that helps avoid knock and keeps performance tidy.
• How should owners source the right knock sensor for a real Splash?
  Shop by VIN and engine code (K10B/K12B or DDiS) to avoid mix-ups. The sensor typically mounts on the block beneath the intake side, follow the manual for torque and harness routing, and clear ECU codes after fitment.
