Parts for your 2018 Suzuki Splash-Crank angle sensor

2018 Suzuki Splash crank-angle sensor – what it does and when to replace it

Yes, the 2018-registered Suzuki Splash uses a crank-angle sensor (also called a crankshaft position or CKP sensor). This is documented across technical sources including Suzuki workshop manuals for the K10B/K12B petrol and 1.3 DDiS diesel engines, OEM parts catalogues, and independent data platforms such as Autodata and Bosch ESI. Even though Splash production wrapped up earlier in many markets, the engines fitted to late-registered cars are the same and rely on a CKP sensor for engine management.

On the Splash, the crank-angle sensor tells the ECU exactly where the crankshaft is in its rotation and how fast it’s spinning. That timing info is the backbone for spark and fuel control, so the engine fires up cleanly, idles smoothly, and uses petrol efficiently. Lose that signal and you’ll cop hard starting, random stalling, a dead tacho, or a no-start. The ECU will usually log codes like P0335–P0339 when the signal goes walkabout.

This sensor is “fit-and-forget” with no scheduled service interval. As part of regular servicing, it’s worth a quick look for oil contamination at the front main seal area, cracked wiring insulation, or a loose connector. Avoid blasting the area with a pressure washer. If you’re chasing intermittent cut-outs or long cranks when hot, scan it first—don’t just throw parts at it.

Location-wise, on the K10B/K12B petrol engines the sensor is typically mounted low on the front of the block near the crank pulley/timing cover. On the 1.3 DDiS diesel it’s usually on the gearbox bellhousing reading the flywheel teeth.

If it’s cactus and needs swapping, most home spanner-users can handle it:

• Disconnect the battery and let the car cool.
• Unplug the sensor connector under the bonnet.
• Remove the retaining bolt, ease the sensor out, and catch the O-ring.
• Lightly oil the new O-ring, refit the sensor, and torque the bolt to spec (check the Suzuki manual).
• Reconnect, clear fault codes, and confirm no leaks. An idle relearn may be needed on some ECUs.

Genuine or quality-brand aftermarket sensors are the go, cheapies can cause misfires or speed signal dropouts. If in doubt about engine variant or fitment, verify by VIN before ordering.

Where is the crank-angle sensor on a 2018 Suzuki Splash?

On the K10B/K12B petrol engines it’s usually tucked low at the front of the engine, reading a reluctor on the crank behind the lower timing cover area. On the 1.3 DDiS diesel, look at the gearbox bellhousing where it reads the flywheel. Access can be tight, so a small ratchet and a good torch help.

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

Typical signs include extended cranking, engine stalling when hot, rough running, erratic or dead tachometer, and stored OBD-II codes like P0335–P0339. If it cuts out and restarts after cooling, that’s a classic heat-soak failure. Always check wiring and connectors before condemning the sensor.

Do crank-angle sensors need servicing or regular replacement?

No scheduled replacement is required. They’re sealed and designed to last the life of the engine. During routine servicing, just inspect for oil contamination, chafed wiring, or loose connectors. Replace the sensor only if fault codes or testing confirm it’s not providing a stable signal.
