Parts for your 2008 Suzuki Splash-Crank angle sensor

2008 Suzuki Splash crank angle sensor: what it does and how to look after it

Yes, the 2008 Suzuki Splash does use a crank angle sensor (also called a crankshaft position sensor). This isn’t guesswork — Suzuki’s factory workshop information for the K10B 1.0 and K12B 1.2 petrol engines includes specific removal/installation steps and wiring for the crankshaft position sensor, and the engine management diagrams show the ECU using its signal for ignition timing and fuel injection. Trade data sources such as Autodata list the CKP sensor under component locations and fault codes (e.g., P0335/P0336), and the 1.3 DDiS diesel (Fiat/GM Multijet with Bosch EDC) also references a CKP input for synchronisation. These technical references confirm the Splash relies on a crank angle sensor for normal running.

On the 2008 Splash, the crank angle sensor’s job is to tell the ECU exactly where the crank is in its rotation and how fast it’s spinning. That lets the ECU fire the coils and injectors at the right moment, trim timing for cold starts and knock control, and coordinate with the cam sensor for variable valve timing on K-series engines. If that signal drops out, the Splash can crank but not start, stumble, or cut out once warm.

It’s not a scheduled service item, but it deserves a look-in during routine servicing. A sensible approach is:

• Scan for fault codes and check live data for a steady crank signal, especially if there have been hard-starts or misfires.
• Inspect the sensor connector and harness near the front/side of the block for oil wicking, heat hardening or chafing.
• Make sure the sensor tip and trigger wheel area are clean — excess sludge or metallic debris can distort the signal.

Replacement is straightforward for most Splash variants: disconnect the battery, unplug the sensor, remove the retaining bolt, and ease the sensor out. Lightly oil the O-ring on the new unit, seat it fully, and refit the bolt to spec. Always clear codes and verify a clean crank signal on the scan tool. If faults persist, check crank trigger wheel runout and confirm cam sensor correlation — a stretched timing chain or slipped reluctor can mimic a dud sensor.

Common symptoms owners notice include intermittent no-start when hot, sudden stalling at lights, a bouncing tacho while cranking, and richer-than-usual fuel use. Given the modest cost and the high impact on drivability, many workshops will recommend proactive replacement once a CKP shows intermittent dropout or damaged wiring. Keeping good oil quality and fixing any leaks around the front cover also helps the sensor live a long and happy life.

Popular questions about the 2008 Suzuki Splash crank angle sensor

Where is the crank angle sensor on a 2008 Splash?
On most K10B/K12B petrol Splashes, it’s mounted low on the engine block near the crank pulley area, reading a toothed reluctor on the crank. Access is from the front or side under the bonnet, sometimes the splash guard underneath needs to come off for room. The 1.3 DDiS diesel also has the sensor at the crank, but access can vary with ancillary layout.

What are the signs the Splash’s crank sensor is failing?
Typical giveaways are hard starting (especially hot), random stalling, no-start with a working starter, and engine light with codes like P0335/P0336. A scan tool will often show an RPM drop-out during cranking. Before condemning the sensor, check the connector, harness, and for oil intrusion at the plug.

Can a faulty crank sensor damage the engine?
It usually won’t cause mechanical damage by itself, but it can leave the Splash stranded or running poorly. Prolonged misfires or rich running from a bad signal aren’t ideal, so it’s best to diagnose promptly. Replacing the sensor and sorting any wiring or timing issues restores proper ignition and fuel control.
