Parts for your 2015 Suzuki Splash-Crank angle sensor

2015 Suzuki Splash crank-angle sensor (crankshaft position sensor)

Based on technical sources including the Suzuki Splash/Ritz Workshop Manual for K10B/K12B engines (Engine Control System section), the Suzuki Electronic Parts Catalogue for Splash/Ritz (2015), and mainstream workshop literature for the twin Opel/Vauxhall Agila B platform, the 2015 Suzuki Splash is fitted with a crankshaft position sensor—commonly called a crank-angle sensor. It’s a core input the engine control module relies on to run the engine at all.

This little sensor reads a toothed wheel on the crank to pinpoint crank angle and speed. With that, the ECU times spark and fuel injection down to the degree, manages starting, and monitors for misfires. If the crank-angle sensor drops out, the Splash can be a pig to start, cut out when hot, misfire, or refuse to fire altogether. The check engine light usually joins the party with codes like P0335–P0339. On the K10B and K12B, the sensor is typically mounted low on the block near the crank pulley, with a short harness to a top-side connector under the bonnet.

It’s not a routine service item, but a bit of attention goes a long way. Keep an eye out for oil leaks that can soak the connector, heat-brittled loom sections near the engine mount, or corrosion in the plug. When replacement is needed, use an OE or quality-brand sensor and inspect the trigger wheel for damage or wobble while you’re there. Swap-over is generally straightforward: disconnect the battery, unplug the sensor, remove the single retaining bolt, wiggle the sensor free, lightly clean the bore, then seat the new unit and snug the bolt to factory spec. Route the loom exactly as original, click the connector home, clear fault codes, and give it a start. No special coding is normally required, the ECU picks it up right away. If starting is still crook, check crank and cam timing, battery voltage during crank, and the condition of the engine earths. Done right, a fresh crank-angle sensor restores clean starts, smooth idle, and proper fuel economy—keeping the Splash happy for many more kilometres.

• Common symptoms: hard/no start, random stalling, rough idle, loss of power, MIL on (P0335–P0339).
• Good practices: keep oil and coolant off the connector, protect the loom, and verify the trigger wheel.
• Service tip: clear codes after replacement and road test to confirm stable RPM and no return of faults.

Popular questions about 2015 Suzuki Splash crank-angle sensors

Where is the crank-angle sensor located on a 2015 Splash?
It’s mounted low on the engine block near the crankshaft pulley on the timing cover side. You’ll usually see one small retaining bolt and a short wiring lead that plugs into a connector higher up under the bonnet. Access is from underneath or through the right wheel arch with the liner eased back.

What are the tell-tale signs the sensor is failing?
Typical behaviour includes long crank or no start, sudden stalling once hot, uneven idle, and the check engine light with codes like P0335. Intermittent faults can mimic fuel or ignition issues, so always scan for codes and check live RPM data—if RPM reads zero while cranking, the sensor or its wiring is suspect.

Does a new sensor need programming?
On the Splash, a replacement crank-angle sensor doesn’t normally need coding. Fit the new part, clear any stored faults, and the ECU will recognise it. If the light returns, inspect wiring, connectors, and the trigger wheel, and ensure battery voltage isn’t sagging during crank.
