Parts for your 2023 Suzuki Splash-Temperature sensors

2023 Suzuki Splash temperature sensors — applicability and guidance

Based on published technical and model-history sources — including Suzuki’s global model chronology, European catalogue data for Splash production (circa 2008–2014), and Maruti Suzuki documentation noting the Ritz (Splash twin) ending around 2016 — there is no factory 2023 Suzuki Splash. Because the model wasn’t built for that year, a “2023 Suzuki Splash temperature sensors” listing isn’t relevant to a genuine 2023 model-year vehicle.

What often happens in Australia and New Zealand is that a used import or previously unregistered vehicle can be first complied or first registered locally in 2023. Registration paperwork may show 2023 as a first NZ/AU use date, but the actual build year for the Splash is typically 2008–2016. For those vehicles, temperature sensors absolutely exist and are critical: the engine coolant temperature (ECT) sensor informs the ECU for cold starts and fan control, intake air temperature (IAT) helps fuel trims, and an ambient sensor feeds the climate control and dash display. Workshop and owner’s manuals for K10B/K12B Splash engines describe these sensors and their diagnostic trouble codes in detail.

So while temperature sensors aren’t “used on a 2023 Suzuki Splash” due to the model-year mismatch, they are very much used on the 2008–2016 Splash that many owners in AU/NZ drive today. The practical next step is to match parts by VIN, engine code (K10B/K12B), and connector style rather than relying on a 2023 model-year tag. That ensures the right sensor calibration, thread, and plug fit.

• Check the build plate or VIN decode to confirm the actual model year (usually pre-2017 for Splash/Ritz).
• Identify engine code (K10B 1.0L or K12B 1.2L) to select the correct ECT/IAT sensor.
• If symptoms include hard cold starts, erratic idle, rich running, high fan speed, or a stuck temp gauge, scan for ECT/IAT DTCs (e.g., P0115–P0119 range codes) before ordering parts.
• When replacing an ECT sensor on these models, refresh coolant and bleed air, poor coolant condition can damage a new sensor.

Technical basis: Suzuki model-history listings for Splash production run, Maruti Suzuki announcements on Ritz discontinuation, and Splash/Ritz K10B/K12B workshop and owner’s manuals detailing ECT/IAT and ambient temperature sensor functions.

Popular questions about 2023 Suzuki Splash temperature sensors

Is there actually a 2023 Suzuki Splash with temperature sensors?

No. The Splash wasn’t produced in 2023. If paperwork shows 2023 in AU/NZ, that’s typically the first local registration or compliance date for an earlier-build Splash (2008–2016). Those vehicles do use engine coolant, intake air, and ambient temperature sensors.

Which temperature sensors are fitted to a Splash and what do they do?

Typical Splash/Ritz models with K10B or K12B engines use an engine coolant temperature (ECT) sensor for fuelling, warm-up, and radiator fan control, an intake air temperature (IAT) sensor for fuel trims, and an ambient sensor for the climate system and display. Faults can cause hard starts, rough idle, high fan speeds, poor economy, or a wonky temp gauge.

How should owners pick the right temperature sensor for a Splash registered in 2023?

Match by VIN, engine code, and connector style — not the registration year. Confirm whether it’s K10B or K12B, check the sensor’s thread and plug, and scan for related DTCs. Replacing the ECT sensor is typically straightforward, but always use the correct coolant and bleed the system to avoid false readings.
