Parts for your 2000 Suzuki Jimny-Camshaft sensor

2000 Suzuki Jimny camshaft sensor — what it is, what it does, and when to sort it

Yes, the 2000 Suzuki Jimny is fitted with a camshaft position sensor (CMP). Factory references including the Suzuki Jimny Service Manual for the JB33/G13BB (engine control, section 6E) list the CMP as an ECM input and include diagnostic routines for DTC P0340 (Camshaft Position Sensor Circuit). Suzuki’s Electronic Parts Catalogue for JB33 models also shows a dedicated camshaft sensor for the G13BB engine. Independent data sets used by workshops (e.g., Autodata wiring and DTC charts for 1998–2004 Jimny) likewise document the CMP input and related fault codes. So the camshaft sensor is relevant and used on the 2000 Jimny.

On the G13BB-powered Jimny, the camshaft sensor helps the ECU figure out which cylinder is on its compression stroke. Paired with the crank sensor, it allows accurate fuel synchronisation and spark timing, aiding cold starts, smoother idle, and cleaner emissions. If the sensor signal drops out, the Jimny can usually still run by defaulting to batch injection, but starting can be harder, fuel economy suffers, and a check engine light will pop up.

There’s no scheduled replacement interval for the CMP. It’s a solid-state Hall-effect sensor, so the best “maintenance” is simple: keep the connector clean and dry, make sure the loom isn’t rubbing on the cam cover, and check the O-ring or seal for oil weep. During regular servicing, a quick visual under the bonnet to confirm the plug is seated and the wiring is tidy is time well spent.

When replacement is needed (common tell-tales are MIL on, rough idle, longer crank time, and codes like P0340 or a crank/cam correlation fault), go for an OEM or OE-equivalent unit. Swap-out is typically straightforward with basic hand tools. After fitting, clear the codes and let the ECU complete a warm-up drive so it can relearn fuel trims. If a fresh sensor doesn’t resolve a correlation code, it’s worth checking the crank sensor, connector integrity, and cam timing. These G-series Jimnys use a timing chain, chain wear or guide issues can skew cam/crank phasing and confuse the ECU.

• Common symptoms of a failing CMP: hard starting, misfire at idle, higher fuel use, reduced power, and MIL on.
• Simple prevention: tidy wiring, clean connectors, and fix any oil leaks that can wick into the plug.

Where is the camshaft sensor on a 2000 Jimny?

On most 2000 models with the G13BB engine, the CMP sits at the rear of the cylinder head, reading a trigger on the cam. Access is from the top, towards the firewall. If a vehicle has had an engine swap (e.g., later M13A), location differs.

Is it safe to drive with a dodgy camshaft sensor?

The Jimny may still start and run, but it can be harder to fire up, use more fuel, and feel a bit flat. It’s not ideal to keep driving that way, sorting it sooner avoids poor economy and potential stalling at the worst moment.

Does the camshaft sensor need routine replacement?

There’s no routine interval. Replace it when fault codes or symptoms appear. During regular services, a quick check of the connector and loom is all that’s needed.
