Parts for your 2021 Suzuki Splash-Knock sensor

2021 Suzuki Splash knock sensor — not applicable to this model year

Short answer: a “2021 Suzuki Splash” isn’t a thing, so a 2021 Splash knock sensor isn’t relevant. Technical sources including Suzuki global model catalogues and press materials show the Splash ended production in Europe mid-2010s and was replaced by the Celerio. In India, the Splash’s twin (Maruti Ritz) was discontinued in 2017. There was no factory 2021 Splash, so there’s no 2021-specific knock sensor to fit or maintain.

That doesn’t mean Splash models never used a knock sensor. Earlier Splash variants (2008–2014, petrol K10B/K12B) commonly featured a knock sensor as part of their engine management. Workshop manuals for those engines identify a single block-mounted sensor feeding the ECU to control ignition timing and protect against detonation. But for a 2021 model year query, the part is simply not used because the vehicle itself wasn’t produced.

If someone’s searching for a “2021 Splash knock sensor,” it’s likely a parts listing quirk or an SEO catch-all. If the car in the driveway is a Splash from the late 2000s or early 2010s, that’s the version to reference for servicing. The right approach is to confirm the build year and engine code from the VIN plate and then look the sensor up in Suzuki’s EPC or a trusted parts catalogue.

Practical checks for an earlier-year Splash:

• Run a scan tool: detonation/knock faults often flag as P0325–P0334 ranges.
• Visual check: a small, single-wire or two-wire sensor bolted to the engine block, typically below the intake side.
• Order parts by VIN: ensures correct connector style and calibration for K10B vs K12B.

Technical sources referenced for this conclusion:

• Suzuki global model catalogues and press releases indicating Splash end-of-production in EU and shift to Celerio in the mid-2010s.
• Maruti Suzuki communications confirming Ritz (Indian Splash) discontinuation in 2017.
• Suzuki Electronic Parts Catalogue (EPC) model-year listings for Splash/Ritz.
• Suzuki Splash/Maruti Ritz service manuals for K10B/K12B engines, which include knock sensor details for those earlier engines.

If the vehicle is actually a 2021 Suzuki (for example Ignis, Swift, or Baleno), those engines generally do use a knock sensor, and guidance would need to follow the correct model and engine code for that year.

Popular questions about a 2021 Suzuki Splash knock sensor

Is there a 2021 Suzuki Splash, and does it have a knock sensor?
No. There wasn’t a 2021 Splash in Suzuki’s line-up, so there’s no 2021-specific knock sensor. If the car is a Splash from around 2008–2014, it likely has a knock sensor and parts should be matched to that actual build year and engine code.

How can someone tell if their (earlier) Splash has a knock sensor?
Check the VIN and engine code, then confirm in the Suzuki EPC or workshop info. A physical look under the bonnet helps too: most K10B/K12B Splash engines have a single knock sensor bolted to the block on the intake side. A scan tool throwing knock-related fault codes is another giveaway.

I’m seeing “2021 Splash knock sensor” in online shops. What should I order?
Treat those listings as generic. Use the car’s exact VIN/build year. Order a sensor specified for your engine (K10B or K12B), and follow the workshop manual for installation and torque. That way, the connector style and calibration will be correct, and you won’t be stuck with a part that doesn’t fit.
