Parts for your 2010 Suzuki Splash-Crank angle sensor

2010 Suzuki Splash crank angle sensor — what’s fitted and why it matters

Yes, the 2010 Suzuki Splash uses a crank angle sensor (often called a crankshaft position sensor, CKP). This isn’t optional kit — it’s a core engine control input on both the K‑series petrol engines (K10B/K12B) and the 1.3 DDiS diesel. Technical references confirming fitment include: Suzuki Splash/Opel Agila (B) workshop manuals under Engine Control System (CKP sensor), Suzuki Electronic Parts Catalogue listings for “Crankshaft Position Sensor” on 2010 Splash variants, and Maruti Suzuki Ritz service documentation (the Ritz is the Indian-market Splash twin). These sources describe the CKP signal being used by the ECU for ignition and injection timing and engine speed.

On the Splash, the crank angle sensor reads a toothed reluctor on the crankshaft to tell the ECU exactly where the crank is and how fast it’s spinning. Without that live timing feed, the injectors and coils don’t know when to fire, so start-up and smooth running go out the window. If it drops out, owners will typically see a crank/no-start or abrupt stalling once warm, sometimes with a dead tachometer and a check engine light. Common fault codes are P0335–P0339.

• Typical symptoms: long crank or no-start, intermittent stall, rough idle or misfire, sudden loss of power, MIL on, P0335–P0339 stored, erratic tacho.
• Likely causes: sensor internal failure, heat-soaked wiring/connector issues, metal debris on the sensor tip, damaged reluctor teeth, oil intrusion.

Servicing-wise, the CKP isn’t a scheduled replacement item, but it’s smart to give it attention during major services. A quick visual of the harness routing low on the engine, a check for oil leaks dripping onto the plug, and confirming the connector is clean and latched can save headaches. Because the sensor sits low and faces the crank, it can pick up metallic fuzz, gently wipe the tip if accessible. The air gap is factory set on these engines, so there’s no adjustment — if the sensor or mounting face is damaged, replace it.

Replacing the crank angle sensor is a straightforward driveway job for the confident DIYer, and a short book time for a workshop. Steps are generally: disconnect the battery, safely raise the front, access the sensor low on the block (by the crank pulley/bellhousing area, model dependent), unplug, remove the single retaining bolt, and twist-pull the sensor out. Lightly oil the new O‑ring, install, and tighten to the manufacturer torque spec. Route the loom away from hot exhaust and moving bits, reconnect the battery, and clear codes. Some ECUs may perform a quick relearn after a few kilometres of mixed driving, if an idle relearn is specified in the service manual, follow it. If faults return, dig into wiring continuity and scope the signal — don’t throw parts at it.

Where is the crank angle sensor on a 2010 Splash?

It’s mounted low on the engine facing a reluctor on the crankshaft — typically by the crank pulley at the front or near the gearbox bellhousing, depending on engine/market. Access is usually from underneath after removing splash shields. A torch and a small ratchet help.

Is it safe to drive with a failing CKP sensor?

Not really. A marginal sensor can cut out without notice, causing sudden stalling or a no‑restart once hot. If the light’s on with P0335–P0339 or there are stall/no‑start symptoms, plan repair promptly and avoid long trips until it’s sorted.

Do I need to reprogram the ECU after replacement?

No coding is normally required. Clear any stored codes and let the ECU relearn idle over a short drive. If the manual specifies an idle relearn, follow that procedure. Persistent faults point to wiring/reluctor issues rather than coding.
