Parts for your 2004 Suzuki Jimny-Crank angle sensor

2004 Suzuki Jimny crank‑angle sensor (crankshaft position sensor)

Based on the Suzuki Jimny JB43/M13A factory service manual (engine electrical section and DTC diagnostics), the 2004 Jimny is fitted with a crankshaft position sensor, commonly called a crank‑angle sensor. The OEM wiring diagrams show a dedicated CKP signal fed to the ECM, and Suzuki’s electronic parts catalogue lists a crankshaft position sensor for the 2004 Jimny M13A engine. Independent workshop references (e.g., Autodata/Bosch ESI and Gregory’s/Haynes manuals covering M‑series engines) also specify CKP testing procedures for this model. So yes—this vehicle uses a crank‑angle sensor.

On the 2004 Jimny, the crank‑angle sensor reads a toothed wheel on the crank and tells the ECM exactly where the pistons are. That info is used to time spark and fuel injection, manage idle quality, and detect misfires. If the sensor goes out of whack, the Jimny may crank for ages, stall when warm, refuse to start, or throw a check‑engine light.

There’s no fixed replacement interval—it’s an as‑needed item. As part of routine servicing, a quick visual check goes a long way. Look for heat‑baked wiring, oil contamination around the sensor, or a loose connector. Because it sits near the front of the engine/timing case, it copes with heat, road spray, and vibes, keeping the plug clean and the loom properly clipped reduces intermittent faults.

• Common symptoms: hard starting, random stalling, no tach movement when cranking, and codes like P0335/P0336.
• Quick test tip: on a scan tool, watch engine RPM during cranking—0 rpm points to a dead CKP or its wiring.

Replacement is straightforward for most DIYers. Disconnect the battery, unplug the sensor, remove the single retaining bolt, and ease the sensor out. There’s an O‑ring—lightly oil a new one before seating the replacement to avoid pinching and to keep dust and water out. The air gap is not adjustable on this setup, so if the mounting face is clean and the correct part is used, it’ll sit right. Clear the code and confirm a clean start with steady idle. No coding is normally required on the 2004 Jimny, the ECM reads the new signal straight away.

If the fault returns, it’s worth checking the reluctor wheel for damage, confirming power/ground to the sensor, and comparing camshaft sensor data—mismatched signals can mimic a bad CKP.

• Handy servicing adds: keep oil leaks at bay around the timing cover, avoid cable ties that strain the CKP lead, and use dielectric grease sparingly on the connector seal.

Popular questions about 2004 Suzuki Jimny crank‑angle sensors

Where is the crank‑angle sensor on a 2004 Jimny?
It’s mounted at the front of the engine on the timing cover, reading a toothed reluctor on the crankshaft. Access is from the front of the bay—look low and slightly to the passenger side on RHD models. You’ll see a small sensor with a two‑ or three‑pin plug and a single retaining bolt.

What fault codes point to a bad crank‑angle sensor?
Most commonly P0335 (Crankshaft Position Sensor “A” Circuit) and sometimes P0336 (range/performance). You might also see misfire codes if the signal drops out. Always check wiring and connectors before condemning the sensor.

Does a new sensor need programming?
No special coding is normally required. Fit the correct sensor, clear any codes, and start the engine. If idle is a bit off after battery disconnection, a short drive cycle will allow the ECU to relearn trims.
