Parts for your 2020 Suzuki Splash-Crank angle sensor

2020 Suzuki Splash crank angle sensor (crankshaft position sensor): what it does and how to look after it

Is a crank angle sensor used on a 2020 Suzuki Splash? Yes. Suzuki’s small petrol engines in the Splash range (K10B 1.0L and K12B 1.2L) use a crankshaft position sensor as a core input for the engine control module. This is documented in Suzuki workshop manuals for the Splash/Ritz under Engine Electrical – Crankshaft Position Sensor (CKP), reflected in the Suzuki Electronic Parts Catalogue listings for CKP sensors on K10B/K12B engines, and supported by Suzuki diagnostic procedures referencing OBD‑II DTCs like P0335/P0336 for crank sensor faults. Even though the Splash’s production wrapped up earlier in some markets, vehicles registered and serviced in 2020 still rely on this sensor.

On the 2020 Suzuki Splash, the crank angle sensor (often called a CKP sensor) tells the ECU exactly where the crankshaft is and how fast it’s spinning. That timing info lets the ECU fire the injectors and coils bang on time, which keeps starting crisp, idle smooth, and fuel economy tidy. If the sensor signal drops out or goes messy, the ECU can’t time things properly—hello rough running, hard starting, or a no‑start.

There’s no fixed replacement interval for the CKP on a Splash. It’s a “replace on condition” part, but a little attention during regular servicing goes a long way:

• Check the harness and plug for oil ingress, corrosion, or broken locking tabs.
• Look for damaged loom insulation near the sensor and around the front of the engine.
• If there’s intermittent stalling or a long crank when hot, scan for codes (P0335/P0336) and live‑data dropouts.
• Make sure any oil leaks are sorted—oil can wick down wiring and upset the signal.

Replacement on these engines is generally straightforward for a trained tech: disconnect the battery, unplug the sensor, remove the retaining bolt, and swap the sensor, lightly oiling the O‑ring if fitted. The air gap is typically set by the sensor design, so there’s no shimming to muck about with—just torque the bolt to spec and clear codes. Always use quality OEM‑equivalent parts, cheap sensors can cause phantom misfires or random stalls that’ll drive anyone spare.

Signs it’s time to act include:

• Cranks but won’t start, especially when hot, then starts again once cooled.
• Sudden cut‑out at idle or at a stop, with the tacho dropping to zero.
• Check Engine Light with crank sensor codes and erratic RPM in scan data.

For most Splash owners in Australia and New Zealand, a CKP sensor is a rare replacement during the car’s life, but when it plays up, sorting it promptly restores reliable, fuss‑free motoring.

Popular questions

Where is the crank angle sensor on a 2020 Suzuki Splash?
On K10B/K12B engines it’s typically mounted low on the engine block or timing cover, reading a toothed reluctor on the crank. Access is from the front or underside, depending on splash guards and model specifics. A workshop manual or a quick look from underneath with a torch usually spots the single‑bolt sensor with a two‑ or three‑pin plug.

Can a faulty crank sensor cause stalling and no‑start issues?
Absolutely. If the ECU loses a clean crank signal, it can’t control spark or fuel timing. Symptoms range from random stalls and hard hot‑starts to complete no‑start. A scan showing P0335/P0336 and an RPM signal that drops to zero while cranking is a strong pointer to a failing CKP or its wiring.

Do crank sensors need calibration after replacement?
On the Splash’s petrol engines, the new sensor is plug‑and‑play—no special calibration. Fit the sensor, torque it correctly, check for clean wiring and good battery voltage, then clear any stored codes. If issues persist, inspect the reluctor ring for damage and recheck earths and loom routing.
