Parts for your 2023 Suzuki Splash-Crank angle sensor

2023 Suzuki Splash crank-angle sensor

Yes, the 2023 Suzuki Splash crank-angle sensor is relevant because the Splash platform uses a crankshaft position sensor (often called a crank-angle sensor or CKP) across its petrol K10B/K12B and diesel D13A/1.3 DDiS engines. Technical sources that document this include the Suzuki Splash/Maruti Ritz workshop manuals for K10B/K12B engines (Engine Control System sections), the Suzuki Electronic Parts Catalogue listings for the Splash that include a crankshaft position sensor, and engine management documentation from Denso/Bosch used on these models. While the Splash wasn’t produced as a 2023 model year, any Splash being serviced in 2023 and beyond still relies on this sensor.

What does it do? The crank-angle sensor tracks the crankshaft’s exact position and speed. The ECU uses that signal to trigger spark timing, sequence fuel injection, coordinate with the cam sensor for phasing, run VVT where fitted, detect misfires, and manage cranking and stall recovery. If the signal drops out, the engine may not start or it’ll run poorly.

Is there maintenance? It’s not a scheduled replacement item, but it’s smart to have it checked during routine servicing. A good workshop will:

• Inspect the sensor connector for corrosion, oil ingress, or loose pins.
• Check harness routing for rub-through near the crank pulley or bellhousing.
• Confirm the mounting is snug and the sensor face is clean of metal filings.
• Scan the ECU for stored faults such as P0335–P0339 and review live CKP/RPM data on cranking.

Classic symptoms of a crook CKP include long cranking or no start, random stalling when warm, rough idle, flat spots, and the MIL on. If those show up, get a scan and a proper diagnosis before throwing parts at it.

Replacement tips for the Splash: use quality OEM-equivalent sensors, cheapies can give weak signals. Battery off, connector off, one bolt out, swap the sensor, refit and torque appropriately. On the K12B/K10B, the sensor is typically low on the block near the crank pulley, on the 1.3 DDiS, it’s usually at the bellhousing reading the flywheel. Some ECUs benefit from a crank variation relearn with a scan tool after replacement to tidy up misfire monitoring. Expect modest labour time unless access is tight or the bolt is seized.

With sensible inspection every 20–40,000 kilometres and prompt attention to any start or stall dramas, the Splash’s crank-angle sensor should deliver years of faithful service.

FAQs

Where is the crank-angle sensor on a 2023 Suzuki Splash?
The petrol K10B/K12B usually places it low on the front of the engine, reading a toothed wheel at the crank pulley. The 1.3 DDiS diesel typically mounts it at the gearbox bellhousing, reading the flywheel. Access is from under the bonnet or underneath with the splash shield off.

What fault codes point to a bad Splash crank-angle sensor?
Common codes include P0335 (CKP circuit), P0336 (range/performance), and sometimes P0337–P0339 (low/high/intermittent). You may also see misfire codes if the signal is noisy. Always verify wiring and power/earth first.

Does the Splash need a relearn after replacing the crank-angle sensor?
Many ECUs will run fine without it, but performing a crankshaft position variation learn with a capable scan tool is recommended. It helps the ECU calibrate misfire detection and smooths idle and tip-in behaviour.
