Parts for your 2017 Suzuki Splash-Crank angle sensor

2017 Suzuki Splash crank-angle sensor (crankshaft position sensor): what it does and how to look after it

Relevant technical sources confirm the 2017 Suzuki Splash uses a crank‑angle sensor (commonly called a crankshaft position sensor or CKP). The Suzuki Splash/Ritz service manual for the K10B/K12B engines details the CKP as a primary engine control input, and the Suzuki Electronic Parts Catalogue lists a “Sensor, Crankshaft Position” for Splash variants across K10B, K12B and D13A engines. Independent repair data providers (e.g., Autodata/Haynes) also show the CKP as a key ECU input for fuel and ignition timing on Splash models. That makes the crank‑angle sensor both relevant and fitted on this vehicle.

The crank‑angle sensor on a 2017 Suzuki Splash is the engine’s timekeeper. Mounted near the crank pulley or at the transmission bellhousing, it reads a toothed reluctor wheel on the crankshaft and sends that pulse train to the ECU. From those pulses the ECU knows exact crank position and speed, then sets ignition timing, injector sequencing and checks for misfire. Without a clean CKP signal, the Splash can crank but not start, stumble, or randomly stall when hot.

It’s not a scheduled service item, but it benefits from a bit of care. Keeping oil leaks in check around the front cover, ensuring the harness isn’t rubbing through on brackets, and making sure the connector seal is intact all help longevity. When diagnosing rough running or a no‑start on these Suzukis, scan for faults like P0335–P0339, check live RPM data during cranking, and inspect the sensor tip for metal fuzz from the reluctor.

Replacement is straightforward for a competent tech. Disconnect the battery, lift the bonnet, and access the sensor from below or the right‑hand wheel arch depending on engine. Unplug the connector, remove the retaining bolt, and withdraw the sensor. Lightly oil the new O‑ring, seat the sensor squarely, and torque the bolt to the factory spec. Route the loom exactly as original to avoid heat or chafe. No special programming is typically required, the ECU will sync on first start. Use a quality OEM‑equivalent part, as cheap imitations can give weak signals that trigger intermittent stalls once hot.

Common symptoms owners notice include:

• Cranks but won’t fire, especially after a hot soak.
• Sudden stall at idle or when pulling up to lights, then long crank.
• Check Engine light with P0335‑type codes and erratic tacho behaviour.

If the Splash is clocking up high kilometres or shows those symptoms, a proper diagnosis and timely sensor replacement will keep it starting first pop and running sweet.

FAQs

Where is the crank‑angle sensor on a 2017 Suzuki Splash?
On most K10B/K12B petrol Splash models it’s mounted low on the engine near the crank pulley or at the gearbox bellhousing, reading a toothed ring on the crank. Access is usually from underneath or via the right front wheel arch with the liner eased back.

What are the signs the Splash’s crank‑angle sensor is failing?
Hard starting when hot, random stalls, rough idle, no tachometer movement while cranking, and a Check Engine light with CKP‑related codes (P0335–P0339). Live data showing zero RPM while cranking is a giveaway.

Does the crank‑angle sensor need regular servicing?
It’s not a routine service item. Preventative care is about keeping connectors clean and dry, fixing oil weeps promptly, and securing the harness. Replace the sensor only when faults or symptoms indicate it’s on the way out, and always refit with a new O‑ring.
