Parts for your 2011 Suzuki Sx4-Crank angle sensor

2011 Suzuki SX4 crank angle sensor (crankshaft position sensor)

Yes, the 2011 Suzuki SX4 is fitted with a crank angle sensor, more commonly called the crankshaft position (CKP) sensor. Technical sources confirming this include the Suzuki SX4 Service Manual (2010–2013) under Engine Control System, which details CKP operation and diagnostics (including DTCs P0335–P0339), and the Suzuki Electronic Parts Catalogue listing a “Sensor, Crankshaft Position” for SX4 petrol engines (M16A and J20B). Trade repair databases used across AU/NZ workshops also specify CKP testing and replacement procedures for this model year.

On the SX4, the crank angle sensor reads a toothed reluctor on the crankshaft and tells the ECU exactly where the crank is and how fast it’s spinning. That live signal is the anchor for spark timing and fuel injection, and it pairs with the cam sensor so the ECU knows which stroke each cylinder is on. If the CKP signal drops out, the ECU can’t control timing properly—so running becomes rough, stalling appears out of nowhere, or it simply won’t start. It’s a small part doing a massive job every kilometre.

There’s no routine replacement interval for the CKP on a 2011 SX4, but it deserves attention during servicing. A quick look for oil contamination, loose connectors, chafed wiring near the front of the engine, or corrosion at the plug can save grief later. Typical symptoms of a failing crank angle sensor include:

• Hard starting or no-start when hot or cold
• Random stalling or hesitation under load
• Erratic tacho needle and a check-engine light
• Stored fault codes such as P0335 (CKP circuit) and related variants

Replacement on the SX4 is straightforward for a competent DIYer or any workshop. It’s usually mounted low at the front of the engine reading the crank pulley’s reluctor (some variants read at the bellhousing). Disconnect the battery, unplug the sensor, remove the retaining bolt, swap in the new sensor with a fresh O-ring, and refit. Clear fault codes and let the ECU idle-learn, no special coding is normally required. Expect around 0.5–1.0 hour in labour. Always route the harness away from the belt and pulleys, and if oil leaks are present at the timing cover, fix those as they can shorten a new sensor’s life. Using a quality OE-equivalent CKP keeps warm restarts crisp and timing dead-on for the long haul.

Popular questions about the 2011 Suzuki SX4 crank angle sensor

Where is the crank angle sensor on a 2011 SX4?
On most SX4 petrol engines it’s mounted low at the front of the engine, reading a toothed wheel on the crank pulley. Some variants place it at the transmission bellhousing reading the flywheel. Access is typically from underneath with the splash shield removed. Always confirm by VIN and engine code.

What codes point to a bad crank angle sensor?
Common CKP-related codes are P0335–P0339. Drivers may also see engine speed input codes or intermittent misfire logs when the signal drops out. If those appear with hard starting or sudden stalling, the CKP and its wiring need checking.

Does a new CKP sensor need programming?
No special programming is usually required on the SX4. After fitting, clear codes and let the engine idle for a short period so the ECU can stabilise trims. If issues persist, recheck connector fit, harness routing, and related oil leaks.
