Parts for your 2015 Suzuki Splash-Camshaft sensor

2015 Suzuki Splash camshaft-sensor: purpose, servicing and common questions

Yes, the 2015 Suzuki Splash uses a camshaft position sensor (CMP). This is confirmed in multiple technical sources: Suzuki’s Global Service Manual for the K12B and K10B engines details the CMP within the Engine Control System, the Suzuki Electronic Parts Catalogue (EPC) lists a dedicated camshaft sensor for the Splash/Swift with these engines, and standard diagnostic references such as Autodata include CMP-related fault codes (e.g., P0340/P0341) for this model. The sister vehicle, the Opel/Vauxhall Agila B, also documents a CMP in its technical information system, reinforcing applicability to the Splash platform.

The camshaft-sensor on a 2015 Suzuki Splash is there to let the engine control module know exactly where the camshaft is in its rotation. On the K12B 1.2 and K10B 1.0 petrol engines, it’s essential for accurate sequential fuel injection, spark timing and variable valve timing strategy. That translates into smooth idle, better fuel economy and lower emissions. The diesel D13A variants also rely on cam and crank correlation for precise injection timing. If the CMP signal goes missing or skewed, the Splash can be a pig to start, run rough or default to a limp strategy, and will usually light the check engine lamp with a CMP correlation code.

There’s no scheduled service interval for the camshaft-sensor, it’s a fit-and-forget item. As part of routine servicing, it’s smart to give the connector a quick eyeball for oil wicking, corrosion or a loose fit, especially after rocker cover or timing work. If replacement is needed, the job is pretty straightforward: disconnect the battery, unplug the connector, remove the retaining bolt, ease the sensor out of the cam cover, and check the O-ring. A light smear of clean engine oil on the new O-ring helps it seat without pinching. Refit, nip the bolt to the factory spec, reconnect and clear any stored codes. Use a quality OEM or reputable aftermarket unit so the waveform and signal amplitude play nicely with the Splash’s ECU. If the light returns, check the crank sensor and timing chain alignment—CMP faults can sometimes be the messenger rather than the culprit.

• Hard starting or stalling after start
• Rough idle and flat spots on acceleration
• Poor fuel economy and higher emissions
• Check engine lamp with P0340/P0341
• Limp-home behaviour on some variants

Does the 2015 Suzuki Splash have a camshaft-sensor?
Absolutely. All 2015 Splash petrol engines (K10B/K12B) and the 1.3 DDiS diesel use a camshaft position sensor. Suzuki’s service manual and the EPC list it, and common OBD-II codes for this model include CMP circuit and correlation faults.

Where is the camshaft-sensor on a Splash, and how long to replace?
On K12B/K10B petrol engines it’s mounted at the top of the cylinder head near the timing chain end. On the diesel it’s adjacent to the cam cover. A competent DIYer can usually swap it in 20–40 minutes with basic tools.

Should the camshaft-sensor be cleaned or just replaced?
It’s not a cleaning item. If there’s oil contamination on the connector or a damaged O-ring, that can be addressed. Otherwise, faults are generally cured by fitting a quality replacement and checking wiring integrity and engine timing.
