2022 Suzuki Splash crank-angle sensor: fitment, purpose, and care

Technical sources for the Splash platform confirm a crank-angle sensor (commonly called a crankshaft position/CKP sensor) is used on this vehicle. The Suzuki Splash/Opel Agila B workshop manuals for the K10B 1.0‑litre and K12B 1.2‑litre petrol engines list the CKP sensor as a primary engine management input, mounted near the crank pulley or bellhousing. The Maruti Suzuki Ritz (the Splash’s sister model) factory service manual also details CKP diagnostics and replacement, and Bosch/Denso ECU documentation specifies a crankshaft speed/position input for sequential fuel injection and ignition timing. Based on these technical references, the 2022 Suzuki Splash is fitted with and relies on a crank-angle (crankshaft position) sensor.

On the 2022 Suzuki Splash, the crank-angle sensor tells the ECU exactly where the crankshaft is and how fast it’s spinning. That lets the engine computer fire the spark and inject fuel at the right moment, manage idle stability, detect misfires, and coordinate with the cam sensor for smooth starts and tidy performance. Without a clean signal from this little sensor, the ECU’s flying blind — which is why a dodgy CKP can cause hard starting, random stalling, or a no‑start when hot.

It isn’t a regular “replace-by-kilometres” service item, but it deserves attention during scheduled servicing. A good workshop will:

• Scan for fault codes such as P0335–P0339 and check live data for steady RPM during cranking and idle.
• Inspect the connector and harness routing for heat damage, oil saturation, or chafing near the crank pulley/exhaust.
• Verify the sensor’s mounting, O‑ring condition, and correct air gap to the reluctor ring, keep the tip free of metal filings.

If replacement is needed, the job’s straightforward with the right access. Battery power should be isolated, the retaining bolt removed, and the sensor eased out without twisting the O‑ring to bits. A light smear of clean engine oil on the new O‑ring helps it seat without tearing. The harness must be clipped away from moving parts and heat sources, and the bolt torqued to spec. Many ECUs on Splash engines self‑learn, but a crank/cam relearn with a scan tool can speed things up and avoid a lumpy idle after the swap.

Owners can expect these sensors to last many years, failures often show up first as intermittent hot‑soak no‑starts or a sudden stall with the tacho dropping to zero. Keeping oil leaks sorted and connectors clean goes a long way. When a new sensor is required, sticking with a quality OEM‑grade part helps avoid repeat dramas, particularly in Aussie and Kiwi climates where heat and dust can be unforgiving. Proper diagnosis before replacing parts is key — a tired battery or stretched timing chain can mimic sensor faults on this model.

Popular questions

Where is the crank-angle sensor located on a 2022 Suzuki Splash?

On the Splash’s K10B/K12B petrol engines, the CKP sensor is typically mounted low on the engine near the crank pulley at the front, or at the bellhousing reading the flywheel teeth. It points at a toothed reluctor so the ECU can read crank angle and speed.

Access can be tight with undertrays fitted. A quick visual from underneath with the front end safely raised usually spots the connector and single retaining bolt.

What are the common signs and fault codes of a failing Splash crank-angle sensor?

Classic signs include long cranking, stalling when hot, a dead tacho during crank, and a no‑start until the engine cools. The check engine light may or may not be on.

Typical codes logged by the ECU are P0335 (crankshaft position sensor circuit), P0336 (range/performance), and occasionally P0337–P0339 (low/high/intermittent). Live RPM dropping to zero during a stall is another giveaway.

Does a new crank-angle sensor need programming on a Splash?

Most Splash ECUs will adapt automatically, so no coding is usually required. However, performing a crank/cam relearn with a scan tool can help stabilise idle and improve starting straight away.

If the battery’s been disconnected or multiple sensors were changed, a quick relearn and a short road drive cycle are good practice to let trims and synchronisation settle.
