Parts for your 2020 Suzuki Splash-Camshaft sensor

2020 Suzuki Splash camshaft sensor — purpose, fitment and care

Based on technical sources, the 2020 Suzuki Splash uses a camshaft position sensor. Suzuki factory service literature for Splash/Ritz models with K10B/K12B petrol and D13A (DDiS) diesel engines describes a dedicated “Camshaft Position Sensor” in the Engine Control System section and includes related DTCs (e.g., P0340, P0341). The Suzuki Electronic Parts Catalogue also lists a “Sensor, camshaft position” for these engines, and mainstream workshop data (Autodata/HaynesPro) shows its role in sequential fuel injection and timing. So yes — a camshaft sensor is fitted and relevant on the 2020 Suzuki Splash.

The camshaft position sensor on a Splash is a small, hard‑working bit of kit that lets the ECU know exactly where the camshaft is in its rotation. That info is crucial for clean cold starts, smooth idle, proper spark and fuel timing, and on K‑Series petrol engines, for controlling variable valve timing. If the signal goes missing or drifts, the engine may crank longer, stumble, or drop into limp mode, and the dash will usually light the MIL with codes like P0340 or P0341.

It’s not a scheduled replacement item, but it deserves a look during servicing. Under the bonnet, check the sensor’s electrical connector and loom for chafing, broken clips or oil wicking from a rocker cover seep. A light film of dust is normal, oil inside the plug or green corrosion isn’t. On high‑kilometre K‑Series engines, timing chain stretch or a worn cam sprocket can trigger sensor correlation faults — so don’t just throw a sensor at it without a proper scan and basic mechanical checks.

• Typical symptoms of a crook cam sensor: longer cranking, intermittent no‑start, rough idle, flat spots, poor fuel economy, and fault codes P0340/P0341.
• Basic replacement tips: disconnect the battery earth, unplug the connector, remove the single retaining bolt, and ease the sensor out. Lightly oil the new O‑ring, seat the sensor squarely, and tighten the bolt to the workshop‑manual spec. Clear codes and confirm live‑data cam sync is stable.
• Use OEM or quality aftermarket sensors and avoid mixing old and brittle loom clips — secure the harness so it can’t rub on the cam cover.

If issues persist after replacement, have the Splash checked for wiring faults, ECU pin fit, or timing chain phasing errors. A quick scan‑tool check of cam/crank correlation saves guesswork and keeps the little Suzuki running sweet.

Where is the camshaft sensor on a 2020 Suzuki Splash?

On K10B/K12B petrol engines it’s mounted on the cylinder head at the timing‑chain end, near the cam cover. On the DDiS diesel, it also sits on the head reading a cam reluctor. Access is straightforward under the bonnet: unplug the connector and remove one small retaining bolt.

Can a Splash run with a failed camshaft sensor?

Sometimes it will start and run poorly as the ECU guesses timing, but it may also refuse to start when hot or cold. Expect rough running, limp mode, and stored fault codes. It’s best to diagnose and fix promptly to avoid being stranded.

Do camshaft sensors need regular replacement?

No, they’re replaced on condition. During routine services, inspect for oil contamination, cracked wiring, or loose connectors. If faults appear, test the circuit and confirm with scan‑tool data before fitting a new sensor.
