Parts for your 2007 Suzuki Sx4-Crank angle sensor

2007 Suzuki SX4 crank-angle-sensor (crankshaft position sensor)

Based on the Suzuki SX4 (2007) Service Manual’s Engine Control System section, common OBD‑II diagnostics for P0335–P0339 on the SX4, and OEM parts catalogue diagrams for the M16A and J20A engines, the 2007 Suzuki SX4 is fitted with a crank-angle-sensor, typically referred to as the crankshaft position (CKP) sensor. It’s a key input for the engine control module and very much relevant to this model.

On the 2007 SX4, the crank-angle-sensor keeps the engine computer in the loop about crank speed and exact crank position. That info lets the ECU sync spark and fuel delivery with the cam signal so the SX4 fires up quickly, idles neatly, and pulls cleanly under load. When the sensor signal is weak or missing, expect hard starting, intermittent stalling at lights, rough running, the tacho dropping out, and the check engine lamp with codes like P0335. Left too long, it can strand the car because there’s no spark or fuel timing without a valid crank signal.

There’s no fixed replacement interval—it’s a condition-based item. As part of routine servicing, it’s smart to:

• Visually check the sensor connector and loom for oil wicking, heat damage, or chafing.
• Keep the area clean—grit and oil can affect signal quality or the O‑ring seal.
• If chasing misfires or random stalls, scan for CKP/CMP correlation and live RPM dropouts.

Replacement is straightforward for a competent DIYer. Disconnect the battery, safely raise the front, and access the sensor (mounted near the crank pulley or at the bellhousing, depending on engine). Remove the retaining bolt, twist the sensor free, lightly lube the new O‑ring, install, and torque to the manufacturer’s spec. Clear codes and verify a clean RPM signal on a scan tool. No coding is normally required—if it starts and idles steadily with no returning codes, you’re golden.

Good practices for Aussie and Kiwi conditions:

• Use quality OEM-equivalent sensors, cheapies can give flaky hot-start behaviour.
• Avoid pressure-washing the area under the bonnet—water intrusion kills connectors.
• If the reluctor ring area is accessible, check for debris or damage while you’re there.

Handy kit for the job:

• 10 mm socket/spanner, small extension, torque wrench
• Axle stands/ramps, wheel chocks
• OBD‑II scanner to confirm codes and live RPM

Popular questions

Where is the crank-angle-sensor on a 2007 Suzuki SX4?
On most SX4 variants it’s mounted low on the engine—either by the crank pulley at the front or at the transmission bellhousing. From under the car, trace the loom down the front/side of the block to a small sensor secured by a single bolt. Access is usually easier with the splash shield off.

What are the common symptoms and fault codes of a failing SX4 crank-angle-sensor?
Typical symptoms include long cranking, sudden stalling, rough idle, poor fuel economy, and a dead tacho during a stall. The check engine lamp may show codes like P0335 (CKP circuit) through P0339 (intermittent signal). Heat-soak no‑starts after a short stop are also common signs.

Does a new crank-angle-sensor need programming on the SX4?
Generally, no. The SX4’s ECU reads the new sensor without coding. After installation, clear any stored codes, start the engine, and check live data for a stable RPM signal. If a cam/crank correlation code returns, recheck the connector, wiring, and sensor seating/air gap per the workshop manual.
