Parts for your 2011 Suzuki Splash-Camshaft sensor

2011 Suzuki Splash camshaft sensor – what it does and how to look after it

Based on factory service literature for Suzuki’s K10B/K12B petrol engines and the 1.3 DDiS diesel used in the 2011 Splash, as well as OEM/aftermarket parts catalogues and standard OBD‑II fault references, this model is fitted with a camshaft position sensor. The engine control system uses both crankshaft and camshaft signals for sequential fuel injection, ignition timing, and variable valve timing/phasing. So yes, a camshaft sensor is relevant and used on the 2011 Suzuki Splash.

The camshaft sensor on a Splash does the brains-trust work behind the scenes. It tells the ECU exactly where the cam is in its rotation, so fuel and spark can be timed to each cylinder with precision. On the petrol K‑series engines it’s also key to VVT operation, helping the ECU advance or retard the cam to keep things peppy while sipping fuel. Without a clean cam signal the ECU has to guess, which can mean long cranks, rough idle, flat spots and the dash lighting up with a check engine lamp.

There isn’t really “maintenance” for the sensor itself — it’s a sealed electronic pickup — but a few service habits keep it happy. During routine servicing, it’s smart to inspect the wiring loom and the 3‑pin connector at the sensor for oil wicking, brittle insulation or green crust on the terminals. Any oil leaks from the rocker cover should be sorted, as stray oil can find its way into connectors and cause grief. A quick scan-tool check for stored cam/crank correlation codes is worth doing if the Splash feels off or cranks longer than usual.

If replacement is on the cards, it’s a straightforward job for a competent DIYer with basic tools. Disconnect the battery, pop the bonnet, and locate the sensor on the cylinder head near the cam sprocket (petrol) or at the front of the head (1.3 DDiS). Unplug the connector, remove the retaining bolt, twist the old sensor out, and fit the new unit with a fresh O‑ring lightly oiled. Refit the bolt, reconnect, clear any codes and perform a brief road test. Always use quality OEM‑equivalent parts, cheapies can give flaky signals. If a new sensor doesn’t clear a P0340/P0341, don’t overlook harness damage or, on higher‑kilometre cars, timing chain wear causing cam/crank misalignment. A quick scope trace or a timing inspection can save a lot of part‑darts.

• Common symptoms of a failing cam sensor: hard starting, rough idle, misfires, poor fuel economy, limp mode, VVT errors, and the check engine light.
• Best practice: inspect connectors and leaks at every service, replace the O‑ring with the sensor, verify with a scan‑tool after installation.

Popular questions about the 2011 Suzuki Splash camshaft sensor

Where is the camshaft sensor on a 2011 Splash?
On the petrol K10B/K12B, it’s mounted on the cylinder head near the cam sprocket/timing chain end, typically at the top front of the engine. On the 1.3 DDiS diesel, it sits at the front of the head near the cam pulley. Look for a small, cylindrical sensor with a single retaining bolt and a 3‑pin connector.

What are the tell‑tale signs the Splash’s cam sensor is crook?
Longer cranking when cold, stumbling idle, flat acceleration, poor fuel economy, and a check engine light are the big ones. Scan tools often show codes like cam/crank correlation or cam sensor performance. Because the ECU may fall back to batch injection, it might still run, but it won’t run well.

Does the camshaft sensor need regular servicing?
Not directly. It’s a non‑serviceable electronic part. During normal services, check the wiring and connector for oil, corrosion or damage, and make sure there are no rocker cover leaks. If issues persist after replacing the sensor, consider timing chain stretch or wiring faults before swapping more parts.
