Parts for your 2014 Suzuki Splash-Camshaft sensor

2014 Suzuki Splash camshaft-sensor – what it does and when to replace it

Yes, the 2014 Suzuki Splash uses a camshaft-sensor. Technical sources including the Suzuki Splash/RB series workshop manual, Suzuki Electronic Parts Catalogue (EPC), and professional databases such as Autodata/HaynesPro and Bosch ESI list a camshaft position sensor (CMP) on the Splash’s common engines: the 1.0 K10B, 1.2 K12B petrol, and 1.3 DDiS diesel. These documents show the CMP is fitted to the cylinder head and feeds the ECM with cam phase data for sequential injection and valve timing control.

The camshaft-sensor on a 2014 Suzuki Splash plays a key role in how smoothly the little Suzuki starts, idles and accelerates. Working together with the crankshaft sensor, it tells the engine control module exactly where the cam is in its rotation. That lets the ECM fire the injectors and spark in the right order, run variable valve timing on K-series petrol engines, and keep emissions tidy. If the sensor goes out of whack, the ECM loses its precise timing reference and the Splash can be hard to start, run rough, or drop into limp mode.

There’s no scheduled maintenance for the camshaft-sensor. It’s a solid-state Hall device and is replaced on condition. During regular servicing, it’s worth giving the connector and harness a quick once-over for oil wicking, broken clips or chafe near the rocker cover. Clean engine oil and timely rocker cover gasket repairs help prevent contamination at the sensor. If a warning lamp pops up with codes like P0340/P0341 or cam/crank correlation faults, proper diagnosis comes first: scan data, visual checks, and, where available, a scope pattern. Don’t overlook stretched timing chains or VVT issues that can mimic a dud sensor.

Replacement is usually straightforward for DIYers with basic tools. Disconnect the battery, unplug the connector, remove the retaining bolt, swap the O-ring if supplied, fit the new sensor, and reconnect. Clear codes and perform a road test, some vehicles may need an idle relearn. On K12B and K10B engines, the sensor sits on the cylinder head near the cam sprocket area, on the DDiS, it’s mounted at the cam cover. Access typically takes 10–30 minutes. Choose a quality OEM-equivalent sensor to avoid erratic signals and false faults.

If the Splash still cranks a long time, stalls at idle, or shows rough running after replacement, get a technician to check fuel trims, timing chain wear and VVT operation so the real culprit isn’t missed.

• Common symptoms: long crank, erratic idle, hesitation, poor fuel economy, limp mode, MIL with P0340/P0341.
• Best practice: verify power/ground/signal before replacing, inspect loom routing and oil leaks at the rocker cover.
• Parts tip: replace the O-ring and ensure the connector seal is seated to keep moisture out.

FAQs

Does the 2014 Suzuki Splash definitely have a camshaft-sensor?
Yes. The Suzuki workshop manual and EPC for the RB-series Splash list a camshaft position sensor on the 1.0 K10B, 1.2 K12B and 1.3 DDiS engines. It’s mounted on the cylinder head/rocker cover and feeds the ECM with cam phase data.

What are the signs the Splash’s camshaft-sensor is failing?
Hard starting, rough idle, hesitation, poor fuel economy, and a check engine light are common. Fault codes often include P0340/P0341 or correlation errors with the crank sensor. Always verify wiring and timing-chain condition before calling the sensor.

Is it safe to keep driving with a dodgy camshaft-sensor?
The engine may run, but it can stall, surge or drop into limp mode. Prolonged misfires risk catalyst damage. It’s best to diagnose and repair promptly so the Splash stays reliable and efficient.
