Parts for your 2013 Suzuki Sx4-Crank angle sensor

2013 Suzuki SX4 crank-angle sensor (crankshaft position sensor): purpose, service tips, and replacement advice

Technical sources confirm the 2013 Suzuki SX4 is fitted with a crank-angle sensor, commonly listed by Suzuki as the crankshaft position sensor (CKP). The Suzuki SX4 Workshop/Service Manual (Engine Control System section, DTC P0335/P0336 diagnostics) and OEM parts catalogues both show a CKP sensor for the M16A 1.6L and J20B 2.0L petrol engines. Independent data services used in workshops across AU/NZ also document testing and replacement procedures for this sensor on the 2013 SX4.

On the SX4, the crank-angle sensor feeds the engine control module precise crankshaft speed and position signals. That data is used to time spark and fuel injection, control idle quality, and keep emissions tidy. If the signal is missing or erratic, the engine can be a pig to start, stall at the lights, misfire under load, or refuse to run at all. Fault codes commonly tied to a crook CKP include P0335 and P0336.

This isn’t a scheduled service item with a set replacement interval, it’s a fit-and-forget component until symptoms or scan-tool data say otherwise. Still, a quick look during a major service doesn’t hurt. On the M16A, the sensor typically sits near the crank pulley/front of the block, on the J20B it may be mounted by the bellhousing. A visual once-over for damaged wiring, loose connectors, oil ingress, or metal filings stuck to the magnetic tip can catch trouble early.

When replacement is needed, best practice in workshops is straightforward:

• Confirm the fault with scan data and, if available, an oscilloscope pattern test.
• Disconnect the battery, unplug the sensor, remove its retaining bolt, and ease the sensor out.
• Lightly oil a new O-ring, seat the new sensor squarely, torque the bolt to spec, and route the loom away from heat and sharp edges.
• Clear codes, perform a warm restart, and verify clean CKP signal and stable idle.

Quality matters here. Genuine or reputable OEM-equivalent sensors tend to give reliable signal quality that the SX4’s ECU is happy with. If the sensor face is dirty with fine metallic fuzz, a gentle clean can restore signal, but if the engine has cut out on the move or shows intermittent loss of RPM on live data, replacement is the safe call. A failing CKP can mimic a bad coil or fuel issue, so proper diagnosis saves time and coin.

Popular questions

Where is the crank-angle sensor on a 2013 Suzuki SX4?
On most 1.6L M16A engines it’s mounted low on the front/right side of the engine near the crank pulley. On 2.0L J20B variants it’s typically by the transmission bellhousing reading a tone wheel on the crank. Exact position can vary slightly by market and drivetrain, so a quick peek from under the bonnet or beneath the car helps.

What are the symptoms of a failing crank-angle sensor on the SX4?
Owners often report hard starting, random stalling, misfires, a dead tachometer during cranking, or “Check Engine” with codes like P0335. Live data may show RPM dropping to zero even while the engine is still spinning. If it dies hot and restarts after cooling, the sensor can be heat-soaked and on the way out.

Can the crank-angle sensor be cleaned, or must it be replaced?
If the tip has light metallic debris, a careful clean can restore a good signal. However, if the sensor is internally failing or the wiring is damaged, cleaning won’t fix it. Given the modest cost and critical role, replacement with a quality unit is often the smarter move after proper diagnosis.
