Parts for your 2010 Suzuki Splash-Camshaft sensor

2010 Suzuki Splash camshaft sensor – what it does and how to look after it

Yes, the 2010 Suzuki Splash uses a camshaft position sensor. Suzuki’s workshop information for the Splash petrol engines (K10B 1.0 and K12B 1.2) and the Fiat‑sourced 1.3 DDiS diesel shows the engine control module relies on both a crankshaft position sensor and a camshaft position sensor (CMP) for timing and fuel control. The factory wiring diagrams and engine management diagnostics list CMP circuit checks and DTCs such as P0340/P0341, and the parts catalogues for Splash/Agila B specify a CMP mounted at the cylinder head. Those technical sources confirm the sensor is fitted and very much relevant to this model.

On the 2010 Splash, the camshaft sensor tells the ECU which stroke each cylinder is on so it can run true sequential fuel injection, sync ignition events, and manage variable valve timing where fitted. Without a clean cam signal, the engine may fall back to batch injection or refuse to start, and it’ll often run rough as guts, use more fuel, and trigger the MIL.

Typical signs the CMP is unhappy include hard starting (especially warm), misfires at idle, sudden stalling, sluggish throttle response, and fault codes P0340/P0341 or cam/crank correlation faults. Because wiring issues and timing chain wear can mimic a bad sensor, proper diagnostics matter before throwing parts at it.

There’s no scheduled replacement interval for the cam sensor on a Splash. As part of servicing, a tech will usually: check for stored cam-related DTCs, inspect the sensor connector under the bonnet for broken locks, oil ingress or green corrosion, make sure the harness isn’t chafing, and glance for oil leaks from the rocker cover that could contaminate the sensor.

If replacement is needed, the job is straightforward for a competent DIYer with basic tools:

• Disconnect the battery negative and give the area a quick clean so no grit drops into the timing area.
• Unplug the 3‑pin connector, remove the retaining bolt, and withdraw the sensor from the cylinder head (it’ll have an O‑ring).
• Lightly oil a new O‑ring, seat the new sensor squarely, and tighten the bolt to the manufacturer’s spec. Reconnect the plug firmly.
• Clear fault codes and road‑test. If a correlation code returns, have the timing chain condition and cam/crank signals scoped.

Good quality aftermarket or genuine sensors both work well on these cars, the key is using a known brand and fixing any wiring issues at the same time. A tidy connector, a healthy battery, and up‑to‑date ECU grounds will keep the cam signal crisp and the Splash running sweet as.

Popular questions

Does a 2010 Suzuki Splash actually have a camshaft position sensor?
It does. Factory service information for the Splash/Agila B platform shows a dedicated camshaft position sensor used for sequential injection and timing control, and related DTCs (like P0340) are defined in the diagnostics.

Where is the camshaft sensor on a 2010 Splash?
It’s mounted on the cylinder head near the camshaft sprocket under the engine cover, with a 3‑pin connector. On the petrol engines it’s at the top/front end of the head, easy to spot once the plastic cover is off.

Is it safe to drive with a dodgy camshaft sensor?
Short trips may be possible, but it’s not ideal. A failing CMP can cause hard starting, stalling, rough running and higher fuel use. Continued driving can mask other timing issues, so it’s best to get it diagnosed and sorted promptly.
