Parts for your 1997 Suzuki Swift-Camshaft sensor

1997 Suzuki Swift camshaft sensor: is it actually fitted?

For the 1997 Suzuki Swift sold in Australia and New Zealand (SF series), a separate, stand-alone camshaft position sensor isn’t used. Engine phase and timing information is provided either by the distributor’s internal pickup (often called a crank/cam angle sensor within the distributor) or by a crankshaft position sensor, depending on the engine variant. So a bolt-on camshaft sensor on the cam cover or head simply isn’t a thing on these cars.

Why it’s not used comes down to how Suzuki engineered the ignition and fuel systems of the day. These Swifts run either batch-fire injection or distributor-based ignition where the ECU can derive the necessary timing reference from one or two existing sensors. It kept the system simple, reliable and cheap to service—very much in keeping with the Swift’s no-fuss design.

• G10 1.0L 3‑cyl: typically uses a crankshaft position sensor and wasted-spark ignition, no separate cam sensor.
• G13BA/G13BB 1.3L SOHC: uses a distributor with an internal magnetic/optical pickup that feeds the ECU, no external cam sensor.
• G13B 1.3L DOHC (GTi, where applicable): uses an optical sensor inside the distributor providing NE and G signals, again, no stand-alone cam sensor.

For owners, that means if a parts catalogue lists a “camshaft sensor” for a 1997 Swift, it usually refers to the pickup inside the distributor or it’s a catalogue cross-over error. If you’re chasing cam/crank correlation or misfire faults, the common checks are the distributor pickup, wiring/connectors, crank sensor (if fitted), base timing, and timing belt alignment—not a separate cam sensor on the head.

Technical sources that document this setup include:

• Suzuki Swift SF413/SF310 (1995–2000) Factory Service Manual – Engine Electrical and Ignition sections: distributor with internal signal rotor/pickup, no separate CMP component listing.
• Haynes Repair Manual, Geo Metro/Suzuki Swift 1989–2001 – Ignition system: pickup coil/optical sensor within distributor provides engine position signals.
• Autodata/Autologic technical data for 1990s Suzuki Swift – Wiring diagrams show distributor signal (NE/G) or CKP, no discrete camshaft sensor on SF models.

As always with 1990s models, regional specs can vary a touch. If you’re unsure, check your VIN-coded service info or peek under the bonnet: if there’s a distributor, that’s where the “cam signal” lives.

• Where is the camshaft sensor on a 1997 Suzuki Swift?
  There isn’t a separate one. On distributor-equipped engines, the “cam” signal is generated by the pickup inside the distributor. Some 1.0L setups use only a crankshaft position sensor with wasted-spark ignition, so there’s still no stand-alone cam sensor to find.
• Why do parts stores list a camshaft sensor for this model?
  It’s usually catalogue overlap or a naming quirk. Many databases bundle the distributor pickup under “cam/crank sensor.” On these Swifts, replacement typically means servicing or replacing the distributor pickup assembly, not fitting a separate cam sensor on the head.
• What should be checked if there’s a P0340/P0341-type fault?
  On a 1997 Swift, those codes commonly point to the distributor pickup, wiring, poor grounds, or a timing belt that’s stretched or misaligned. Also verify the crank sensor (if fitted), ECU connectors, and base ignition timing before condemning parts.
