Parts for your 2002 Suzuki Jimny-Crank angle sensor

2002 Suzuki Jimny crank-angle sensor (crankshaft position sensor)

Based on factory documentation and professional data sources, the 2002 Suzuki Jimny is fitted with a crank-angle sensor, more commonly listed by Suzuki as the crankshaft position (CKP) sensor. The Suzuki Jimny SN413 Service Manual (EC section for the M13A engine) specifies a CKP sensor as a key input to the engine control module, and OEM parts catalogues for 2002 Jimny models list a replacement CKP sensor for the M13A. Trade databases used in workshops also map fault codes like P0335–P0339 to the Jimny’s CKP circuit, confirming its presence and function.

On a 2002 Jimny, the crank-angle sensor’s job is to track the exact position and speed of the crankshaft so the ECU can time spark and fuel precisely. Without that signal, the Jimny either won’t start or will run poorly. The sensor typically reads a toothed wheel at the front of the engine near the timing cover, sending a clean on/off pulse the ECU turns into rpm and crank angle.

Owners who use their Jimny for everyday commuting and a bit of off-road work will benefit from keeping an eye on CKP health. It isn’t a scheduled service item, but it does appreciate a bit of preventative attention when you’re under the bonnet:

• Look for oil leaks at the crank seal or timing cover—oil can foul the sensor face and wiring.
• After deep water crossings or muddy tracks, check the connector for moisture or grit and apply a light smear of dielectric grease to the seal.
• At service time, visually inspect the harness where it routes past the front of the engine for rub-through or heat damage.

Typical symptoms of a crook CKP sensor include hard starting, random stalling when warm, a dead tacho during crank, uneven idle, and the check engine light with codes like P0335. If it’s on the way out, replace rather than attempt to clean a failing unit—internal failures are common as sensors age.

Replacement is straightforward with basic tools: disconnect the battery, let the engine cool, unplug the sensor, remove the retaining bolt, and swap the sensor and O-ring. Keep the sensor tip clean, route the loom away from hot or moving parts, and tighten to the factory spec in the service manual. Most 2002 Jimnys don’t need programming after a CKP change—clear codes, start the engine, and let it reach operating temperature so the ECU can settle trims. Using a quality OEM or reputable aftermarket sensor will save headaches and keep the little 1.3 humming along smoothly.

Popular questions

Where is the crank-angle sensor on a 2002 Jimny?
It’s mounted at the front of the engine, reading a toothed wheel near the crank pulley/timing cover area. Access is from the front of the bay, on some cars, removing a splash shield makes life easier.

What are the signs the Jimny’s crank-angle sensor is failing?
Hard starting or no start, intermittent stalling (often once hot), rough idle, poor fuel economy, and the check engine light with codes like P0335 are classic signs. The tacho may also drop to zero during crank.

Does the ECU need a relearn after replacing the sensor?
Generally no special programming is required on the 2002 Jimny. Clear any stored codes, start the engine, let it warm up, and take a short drive. If idle is unstable, perform a basic idle relearn procedure per the service manual.
