2009 Suzuki Splash Camshaft Sensor — What It Does and How to Look After It

Yes, the 2009 Suzuki Splash uses a camshaft position sensor across its common engines (1.0 K10B, 1.2 K12B petrol, and 1.3 DDiS/Multijet diesel). This is confirmed by Suzuki’s service literature for K-series engines (Engine Control System sections), the Suzuki Electronic Parts Catalogue listings for the Splash/Swift of the same era, and independent workshop data providers such as Autodata and Bosch ESI[tronic], all of which show a camshaft position sensor input for sequential injection, ignition timing, and—on K-series with VVT—cam phasing feedback.

On the 2009 Splash, the camshaft sensor is a small, solid-state unit that reads the position of the cam relative to the crank. The engine control module uses that signal to fire injectors in the right order, sharpen ignition timing at idle and cold start, and manage variable valve timing where fitted. If the signal goes walkabout, the ECU can fall back to batch injection and fixed strategies, but owners will usually feel rougher running, a lazy throttle, and a drop in fuel economy. It’s one of those small parts that quietly keeps the whole show tidy under the bonnet.

Servicing is straightforward: there’s no routine replacement interval, so it’s a “replace on condition” item. During scheduled services, a technician will typically check for stored DTCs (think P0340/P0341 style faults), inspect the sensor connector and loom for oil ingress or brittle insulation, and make sure the mounting is tight. Good engine oil and filter changes matter here too—clean oil helps the VVT system behave, which in turn keeps the cam timing and sensor feedback stable.

• Common signs it’s unhappy: hard starting, misfires at idle, stalling when hot, poor fuel use, and a glowing check engine light.
• Practical checks: scan live data for stable cam/crank synchronisation, wiggle-test the harness, and verify the reluctor target on the cam isn’t damaged.
• Replacement tips: disconnect the battery, swap the sensor with a quality OEM-spec unit, lightly oil the O-ring, torque to spec, clear codes, and confirm sync on a short road test.

Owners in Australia and New Zealand will find these sensors are relatively inexpensive and quick to fit. If the Splash has high kilometres or shows intermittent faults when hot, testing the cam sensor alongside the crank sensor is a smart move.

FAQs

Where is the camshaft sensor on a 2009 Suzuki Splash?
It’s typically mounted at the end of the cylinder head near the camshaft—on K-series petrol engines, usually at the intake cam end, accessed from the top or end of the head. Under the bonnet, look for a small two- or three-pin sensor with a single retaining bolt and a short wiring plug.

What fault codes point to a camshaft sensor issue?
Common codes include P0340 and P0341 for camshaft position circuit and performance. Drivers may also see related misfire or timing codes if the ECU loses reliable cam sync. Always check wiring and oil condition before condemning the sensor.

Can a camshaft sensor be cleaned, or does it need replacing?
If the tip is lightly contaminated with oil mist, a gentle clean can help, but internal electronic faults, heat soak failures, or cracked housings call for replacement. Given the low cost and critical role, fitting a quality new sensor is often the best fix once a fault is confirmed.
