Parts for your 2014 Suzuki Sx4-Crank angle sensor

2014 Suzuki SX4 crank-angle sensor (crankshaft position sensor): purpose, servicing and real-world tips

Yes, the 2014 Suzuki SX4 is fitted with a crank-angle sensor — more commonly called the crankshaft position (CKP) sensor. This is confirmed in Suzuki factory literature for the SX4 engine management system, which details CKP input for ignition and fuel timing and lists related DTCs (e.g., P0335–P0339). The Suzuki SX4 Service Manual for M16A-equipped models covers the “Crankshaft Position (CKP) Sensor” in the Engine Control System section, and the Suzuki Electronic Parts Catalogue also lists a crankshaft position sensor for 2013–2015 SX4/S-Cross variants. Modern Bosch engine control strategies used by the SX4 rely on a CKP signal, so a crank-angle sensor is absolutely relevant on this vehicle.

On the 2014 SX4, the crank-angle sensor is the ECU’s timekeeper. It reads a toothed reluctor on the crankshaft to tell the computer exactly where the engine is in its rotation and how fast it’s spinning. That live data lets the ECU dial in spark timing, synchronise fuel injection, manage variable valve timing where fitted, and monitor for misfires. Without a clean CKP signal the SX4 can be hard to start, run roughly, or stall, and in many cases it simply won’t fire at all.

It’s not a routine replacement item in a normal service schedule, but it does pay to keep an eye on it as kilometres rack up. Signs the SX4’s crank-angle sensor or its wiring may be unhappy include a Check Engine light with codes like P0335 or P0336, intermittent no-starts when hot, sudden stalling, or a tachometer that drops to zero while cranking.

• Good practice during servicing: check the sensor connector for oil ingress or corrosion, make sure the harness hasn’t rubbed through on brackets, and clear any debris or road grime around the mounting area.
• If replacement is needed: disconnect the battery, access the sensor (typically at the transmission bellhousing or near the crank pulley depending on engine variant), remove the retaining bolt, swap the O-ring, and refit. Use an OEM-quality sensor, route the loom exactly as factory, then clear fault codes and perform a CKP/CMP relearn with a scan tool if required. A quick road test and warm restart check seals the deal.
• Helpful tip: heat-soak failures are common. If it starts cold but dies hot, the CKP is a prime suspect.

For ANZ owners, a trusted workshop with a scan tool that supports Suzuki relearn procedures will make this a straightforward, low-drama job.

Where is the crank angle sensor on a 2014 Suzuki SX4?
Location varies slightly by engine. On many 2014 SX4/S-Cross petrol models it’s mounted low on the engine block reading the flywheel/flexplate at the bellhousing. Some variants place it near the crank pulley at the front cover. Access can be from underneath, a ramp or stands make life easier.

What fault codes point to a bad crank angle sensor on this model?
Common codes include P0335 (CKP circuit), P0336 (range/performance), and sometimes P0337–P0339 (low/high/intermittent). You may also see P0315 (crank variation not learned) after replacement until a relearn is performed.

Does the crank angle sensor need regular servicing?
There’s no scheduled replacement. Treat it as inspect-and-replace: check the plug and loom during routine services, keep oil leaks in check, and only replace the sensor if it shows symptoms or triggers CKP-related fault codes.
