Parts for your 2016 Suzuki Splash-Camshaft sensor

2016 Suzuki Splash camshaft sensor — what it does and when to sort it

According to Suzuki’s factory workshop material for the Splash/Ritz K10B and K12B engines, the model is fitted with a camshaft position sensor (CMP). The engine control section describes diagnostics for DTCs such as P0340/P0341 that reference the CMP, and the wiring diagram shows a three‑wire Hall‑effect cam sensor feeding the ECM. Suzuki’s electronic parts catalogue also lists a dedicated camshaft position sensor for these engines. So yes — the camshaft sensor is relevant and used on the 2016 Suzuki Splash.

On this Splash, the camshaft sensor lets the ECM know exactly where the intake cam is in its rotation. That phase information is essential for quick starts, smooth idle, sequential fuel injection, accurate coil‑on‑plug spark timing, and correct variable valve timing operation. Working in tandem with the crank sensor, it helps the engine run cleanly and efficiently, keeping emissions and fuel use in check.

There’s no routine replacement interval for the CMP — it’s a “fit and forget” part. Still, as kilometres rack up and under‑bonnet heat cycles away, the sensor or its connector can get tired. Common clues include longer cranking, a rough idle, random stalling, flat spots under load, poor fuel economy, or the check engine lamp with codes like P0340/P0341. Because these symptoms can also be caused by wiring issues or a stretched timing chain, a quick diagnosis with a scan tool (or an oscilloscope if you’re keen) is the smart first step.

Replacement is straightforward and usually a 15–30 minute job with basic tools:

• Park up, let it cool, disconnect the negative battery terminal.
• Lift the bonnet and remove the plastic engine cover if fitted.
• Locate the sensor on the cylinder head near the timing chain end, it’s held by a single small bolt and has a 3‑pin plug.
• Unclip the connector, remove the bolt, and ease the sensor out (it’s O‑ring sealed).
• Lightly oil the new O‑ring, seat the new sensor squarely, refit the bolt, reconnect the plug, and reconnect the battery.

Clear any stored codes and take it for a gentle drive. The ECM typically doesn’t need coding on these, it will relearn trims on its own. If a fault returns, double‑check the harness for chafing or oil ingress and verify the crank sensor and timing are all behaving. Use a quality OEM‑equivalent sensor — bargain‑basement parts can cause intermittent grief that’s harder to chase than the original fault.

A quick visual at each service to ensure the connector is clean, the loom isn’t rubbing, and there are no oil leaks onto the sensor will keep it happy for the long haul.

Popular questions

Where is the camshaft sensor on a 2016 Suzuki Splash?
It’s mounted on the cylinder head at the timing chain end of the engine, under the plastic engine cover if your car has one. You’ll see a small sensor with a single retaining bolt and a 3‑pin connector. Access is from the top, so it’s a tidy driveway job with a 10 mm socket.

Can the Splash still run with a faulty camshaft sensor?
Sometimes it’ll start and run but be sluggish, misfire, or stall, other times it won’t start at all. While you’re unlikely to cause immediate mechanical damage, it’s not worth pushing your luck — fuel economy tanks, emissions go up, and it can leave you stranded. Best to diagnose and fix promptly.

Do you need to program the ECM after replacing the sensor?
No special coding is typically required on the Splash. Fit the new sensor, clear the codes, and let the ECM relearn during a short drive cycle. If a code comes back, check the wiring, connector, and timing chain condition rather than assuming the new sensor is at fault.
