Parts for your 2009 Suzuki Splash-Crank angle sensor

2009 Suzuki Splash crank-angle sensor: what it does, how it fails, and when to replace it

Based on OEM technical literature, the 2009 Suzuki Splash is fitted with a crank-angle sensor (also called a crankshaft position sensor). The Suzuki Splash Workshop Manual for K10B/K12B engines (Engine Control System section, DTC P0335 diagnosis), the Suzuki Electronic Parts Catalogue entries for Splash petrol variants (listing a dedicated crankshaft position sensor in the engine electrical group), and the Opel/Vauxhall Agila B (the Splash’s twin) TIS procedures for “Crankshaft position sensor – remove and install (K10B/K12B)” all document the sensor, its wiring to the ECM, and service steps. These sources confirm the part is standard on both the 1.0 K10B and 1.2 K12B petrol engines, and likewise on the 1.3 DDiS diesel.

On a 2009 Suzuki Splash, the crank-angle sensor is the ECM’s timekeeper. It tracks the crank’s exact position and speed so the computer can fire the injectors and coils precisely. No crank signal equals no start, a flaky signal means rough running, misfires, and random stalling at the worst possible time. Because these K-series engines rely on sequential injection and coil control, the CKP data is critical for fuel economy and cold-start manners too.

Owners can think of it as a simple, sealed magnetic pickup that lives down low on the block near the crank pulley or behind the flywheel, reading a toothed reluctor wheel. Over time, heat, oil mist, and road grime can cook the sensor or its connector. A failing unit often throws fault codes like P0335/P0336, triggers a crank/no-start when hot, or causes the tacho to drop out as the engine dies.

As part of routine servicing on a Splash, it’s smart to:

• Scan for stored CKP-related fault codes, even if the MIL’s off.
• Inspect the sensor harness for rubbing, oil contamination, or loose pins, clean the connector and apply dielectric grease sparingly.
• Check for metal filings on the sensor tip if removed, light debris can be wiped away.
• Verify engine earth straps are clean and tight, voltage drops can mimic sensor failure.

Replacement is straightforward for most driveways. Let the engine cool, disconnect the battery, unplug the sensor, remove its single retaining bolt, and ease it out with a gentle twist. Lightly oil the O-ring on the new OEM-quality sensor, seat it squarely, and torque the bolt to spec. On most Splash variants there’s no coding required, the ECM will pick up the new signal straight away. If the idle is a bit wonky after battery-off, a short relearn drive—mixed conditions, a few minutes at idle, then light throttle through the gears—usually tidies it up. Given the relatively low cost of the part and the grief it can cause when it dies, many workshops in Aus/NZ will recommend pre-emptive replacement around high kilometre marks if intermittent faults are appearing.

They’ll also remind owners: if the Splash suddenly cranks but won’t fire after a hot soak, the CKP is high on the suspect list—keep a scan tool handy or arrange a tow rather than cranking endlessly.

Popular questions about the 2009 Suzuki Splash crank-angle sensor

Where is the crank-angle sensor located on a 2009 Suzuki Splash?
It’s mounted low on the engine, reading a toothed wheel on the crank. On K10B/K12B petrol engines, look down the front/side of the block near the crank pulley. Some variants place it at the bellhousing looking at the flywheel. Access is from under the bonnet or underneath with the splash shield off.

If it’s hard to spot, follow the two- or three-pin plug from the lower engine harness, its short lead goes straight to the sensor body.

What symptoms point to a failing crank-angle sensor on a Splash?
Common signs include intermittent no-start when hot, sudden stalling with the tacho dropping to zero, rough idle, and poor throttle response. The check engine light may illuminate with P0335/P0336. It can behave when cold and play up once heat-soaked.

If the starter spins the engine briskly but it won’t catch—and fuel and spark checks are inconclusive—the CKP is a prime candidate.

Does the sensor need programming after replacement?
Typically no. The Splash’s ECM reads the new sensor without coding. After battery disconnection, a brief idle and drive cycle can help the ECM settle trims. If a fault returns immediately, double-check connector pins, wiring, and the sensor’s seating and bolt torque.
