Parts for your 2017 Suzuki Splash-Camshaft sensor

2017 Suzuki Splash camshaft-sensor — purpose, servicing and replacement

Yes, the 2017 Suzuki Splash uses a camshaft position sensor (CMP). Technical sources that specify it include: the Suzuki Splash/Ritz (EBC platform) service manual for K-series petrol engines (K12B/K10B), which details the CMP signal for sequential injection and VVT control, the Maruti Suzuki Ritz workshop manual (India-market Splash) that lists DTCs P0340/P0341 for the camshaft sensor circuit, and documentation for the 1.3 DDiS diesel (Fiat Multijet with Bosch EDC16/EDC17), which requires a CMP input for injection timing and synchronisation. These factory and system manuals all show a dedicated CMP sensor mounted at the cylinder head, used alongside the crank sensor.

On the 2017 Splash, the camshaft sensor’s job is to tell the engine control unit exactly where the cam is in its rotation. That lets the ECU fire the injectors in sequence, keep ignition timing sharp on the petrol models, and manage variable valve timing. On the diesel, it helps nail fuel timing and smooth starting. When the CMP goes out of whack, the car can crank longer, feel flat, surge, or log a check engine light with codes like P0340/P0341. Fuel economy and cold starts can also suffer.

There’s no fixed “maintenance” for a CMP, but it should be checked during regular servicing if there are starting niggles, misfires, or fault codes. Basic care includes inspecting the plug and wiring under the bonnet for oil ingress or chafing, making sure the connector is snug, and confirming the sensor’s air gap and mounting are clean and undamaged. Oil leaks from the rocker cover can contaminate the sensor area, so fixing any seepage early is smart.

Replacement is usually straightforward: disconnect the battery, unplug the connector, remove the retaining bolt, ease out the old sensor, lightly oil the O-ring on the new one, refit and torque to spec, then clear codes and road test. Quality matters—use an OEM or reputable brand to avoid intermittent faults. Many Splash/Ritz variants place the sensor at the top or end of the cylinder head for easy access, but tight bays can still be fiddly, so some owners prefer a pro with a scan tool to confirm live CMP/CKP sync before and after.

• Common signs: hard starting, uneven idle, flat spots, increased fuel use, check engine light (P0340/P0341).
• Good practice: inspect at major services (e.g., 60,000–100,000 km) or when drivability issues appear.
• After replacement: clear codes, verify cam/crank synchronisation, and confirm VVT operation on K-series engines.

Where is the camshaft sensor on a 2017 Splash?
It’s typically mounted on the cylinder head near the camshaft—on K12B/K10B petrol engines it’s at the end of the head under the plastic engine cover. On the 1.3 DDiS diesel it’s also at the head, positioned to read a cam trigger. A quick look under the bonnet at the top/front of the engine usually spots it.

Can it be driven with a faulty camshaft sensor?
If the sensor is playing up, the engine may still run in a fallback mode, but starting can be rough and performance patchy. Prolonged driving isn’t recommended—misfires and poor fuelling can increase emissions and stress other components. Best to scan, fix wiring if needed, or replace the sensor promptly.

Do both petrol and diesel Splash models use a camshaft sensor?
Yes. K-series petrol engines use it for sequential injection and VVT, while the 1.3 DDiS diesel uses it for precise fuel timing and synchronisation with the crankshaft sensor. All variants rely on a good CMP signal for clean starts and smooth running.
