Parts for your 2005 Suzuki Jimny-Crank angle sensor

2005 Suzuki Jimny crank-angle-sensor — what it does and when to service it

On the 2005 Suzuki Jimny, a crank-angle-sensor (also called a crankshaft position sensor or CKP) is fitted and is very much relevant. Technical sources that document this include the Suzuki Jimny service manuals for JB33/JB43 models (Engine/Engine Electrical sections that cover CKP sensor operation, diagnostics and DTCs such as P0335), the Suzuki Electronic Parts Catalogue (EPC) which lists a crankshaft position sensor for 2005 Jimny variants, and independent workshop databases like Autodata and Bosch ESI/tronic that show CKP test and replacement procedures for both G13BB and M13A 1.3-litre engines.

For this Jimny, the crank-angle-sensor is the ECU’s timekeeper. It watches a toothed wheel on the crank, turning that pattern into an exact engine speed and position signal. The ECU then fires the coils and injectors at the right moment, keeps idle stable, and uses it for misfire detection. If it goes out of whack, you can cop hard starting, random stalling, no-spark no-start, or the check engine light with codes like P0335.

There’s no scheduled replacement interval for the sensor itself, but it’s smart to give it some love during major services, especially on higher-kilometre Jimnys that have seen dust, heat and corrugations.

• Inspection: With the bonnet up, check the sensor connector and loom for oil wicking, cracked sheathing or green crust on pins. Trace the wiring where it runs past the block/bellhousing for chafe points.
• Cleaning: If the plug’s dirty, disconnect the battery, unplug the sensor and clean with electrical contact cleaner. Make sure the connector locks positively when refitted.
• Testing: If you’ve got intermittent stall/no-start, scan for codes first. A live-data check for engine RPM during cranking is a quick tell—zero RPM often points at the CKP or its wiring. Resistance and signal tests are outlined in service data (use a proper scope or follow the manual if using a multimeter).
• Replacement: The sensor is a sealed unit, don’t try to strip or “rebuild” it. Use quality OEM-equivalent. Mounting is usually fixed—no adjustment needed—so it’s bolt-out, bolt-in. Clear codes and perform an idle relearn if needed. Most Jimnys don’t require coding for a new CKP.
• Prevention: Oil leaks and heat kill sensors. Fix any front or rear main weeps and keep the engine bay tidy to extend component life.

Look after the crank-angle-sensor and the Jimny will crank, catch and cruise without the fuss—right from cold starts on frosty Kiwi mornings to long Aussie highway runs.

Where is the crank-angle-sensor on a 2005 Jimny?

It’s mounted to the engine near the crankshaft trigger—on many Jimnys that’s low on the block/bellhousing area, reading the flywheel or a reluctor on the crank. Access is from underneath or down the side of the engine, expect a single small retaining bolt and a plugged-in two or three-pin connector.

What are the common symptoms when it fails?

Typical signs are long crank or no-start, random stalling when hot, misfire at low RPM, poor fuel economy, and a check engine light. A scan tool will often log P0335 or related CKP signal faults. If RPM shows zero while cranking, the CKP or its wiring is a prime suspect.

After replacing the sensor, is any programming needed?

Generally, no coding is required on the 2005 Jimny. Clear any stored fault codes, start the engine, and let it idle so the ECU can settle trims. If the battery’s been disconnected, a short idle relearn and a road drive through various speeds and loads helps the ECU stabilise.
