Parts for your 2008 Suzuki Splash-Camshaft sensor

2008 Suzuki Splash camshaft sensor: purpose, servicing and replacement

Yes, the 2008 Suzuki Splash is fitted with a camshaft position sensor (CMP). This applies to the 1.0 K10B and 1.2 K12B petrol engines, as well as the 1.3 DDiS diesel. Technical references that show the CMP include the Suzuki Splash/Swift K-series Engine Service Manual (sections covering “Camshaft Position Sensor” and engine electrical), factory wiring diagrams indicating a CMP signal to the ECM, and the Suzuki Electronic Parts Catalogue listing a camshaft position sensor for these engines. The K-series engines use sequential fuel injection and variable valve timing, both of which rely on a CMP signal for phase reference.

On the Splash, the camshaft sensor’s job is to tell the ECU exactly where the cam is in relation to the crank. That timing info lets the ECU fire injectors in sequence, control spark precisely, and manage VVT on K-series engines. When it’s healthy, cold starts are crisp, fuel economy stays tidy, and the engine runs smoothly under the bonnet at all speeds.

It’s not a scheduled replacement item, but it’s worth a look during routine servicing—particularly the connector and loom where they pass over the head and timing cover. Oil leaks from the rocker cover, heat, and vibration can harden the plug or chafe the wiring. Keeping engine oil clean and at the right level also helps the ECU get clean timing signals, since VVT and cam phasing respond better with fresh oil.

• Common symptoms of a failing CMP: hard or extended cranking, occasional no-start, rough idle, flat spots, poor fuel economy, and a check engine light with codes like P0340/P0341.
• Location: typically at the cylinder head near the timing cover—easy to reach from the top.

Replacement is straightforward for most DIYers with a basic spanner set. Disconnect the battery, unplug the sensor, remove the small retaining bolt, and ease the sensor out. Fit the new one with a fresh O-ring lightly oiled, seat it square, and tighten the bolt snugly to the workshop-manual torque. Reconnect, clear any codes, and let the ECU relearn idle if needed. Use a quality OEM-equivalent part to avoid intermittent faults. If the light comes back or starting is still crook, check the crank sensor and wiring under the bonnet, as these work as a pair for engine timing.

Given the Splash’s simple access and the importance of a clean timing signal, a quick visual check of the CMP and its harness every 10,000–15,000 km service is smart preventative maintenance.

Popular questions

Where is the camshaft sensor on a 2008 Suzuki Splash?
It’s mounted on the cylinder head near the timing cover. On K10B/K12B petrol engines you’ll usually find it on the intake side at the top of the motor. On the 1.3 DDiS diesel it’s also at the head, close to the cam gear area.

Can a bad camshaft sensor cause a no-start on a Splash?
Yes. Without a reliable cam signal, the ECU can’t sync injection and spark properly. Some cars may crank longer or start in a limp strategy, but a failed CMP can definitely cause a hard-start or no-start condition.

Does a new camshaft sensor need programming?
No coding is required for the sensor itself. After fitting, clear any fault codes and allow the ECU to relearn idle if applicable. If issues persist, recheck wiring and verify the crank sensor is reading correctly too.
