2002 Suzuki Swift Camshaft Sensor

Based on Suzuki’s technical literature and parts data, the 2002 Suzuki Swift is fitted with a camshaft position sensor. The Suzuki Service Manual for HT51S/HT81S (M13A engine) describes the Camshaft Position (CMP) sensor and its role in sequential injection and VVT control, and the Suzuki Electronic Parts Catalogue lists a CMP sensor for these models (common part refs include 33220-76G00/33220-76G10). Suzuki’s OBD-II diagnostics also include DTCs P0340/P0341 relevant to this sensor on M-series engines.

On a 2002 Swift, the camshaft sensor tells the engine control module exactly which cylinder is on its compression stroke, so it can fire the injectors and spark at the right time and manage intake VVT where fitted. Working alongside the crank sensor, it keeps starts crisp, idle stable, and fuel burn tidy. When the CMP plays up, owners can cop hard starting, rough idle, flat spots, worse fuel use, or a check engine light.

It’s not a scheduled service item, but it’s worth a look during major services. Under the bonnet, the sensor sits on the cylinder head near the timing chain end. Quick checks that make a difference:

• Inspect the connector and wiring for chafing, brittle insulation, or oil wicking into the plug.
• Check for light oil seepage around the sensor O-ring and the rocker cover—oil contamination can skew the signal.
• Scan for stored codes like P0340/P0341 and review cam/crank sync data if you’ve got a scan tool.

Replacement is straightforward with basic tools. Disconnect the battery negative, unplug the connector, remove the retaining bolt, and ease the sensor out. Lightly oil the new O-ring, seat the new sensor squarely, and tighten the bolt to factory spec—no gorilla torque. Clear any codes and confirm a clean restart and stable idle. Sticking with quality OEM-equivalent sensors helps avoid intermittent gremlins.

If the Swift is racking up kilometres, pairing a sensor swap with a fresh rocker cover gasket (if it’s weeping) keeps the new sensor clean and happy. For no-start or extended crank complaints, rule out a weak battery and crank sensor first, then test the CMP’s 5 V reference, ground, and signal with a multimeter or scope.

Popular questions

Where is the camshaft sensor on a 2002 Suzuki Swift?
It’s mounted on the cylinder head at the timing chain end (right-hand end when facing the engine bay). Look for a small, single-bolt sensor with a two- or three-pin plug. Access is usually from the top with the engine cover off, if fitted.

What are common signs the camshaft sensor is failing?
Tell-tales include extended cranking, rough idle, hesitation on take-off, worse fuel economy, and a check engine light—often with codes P0340 or P0341. Intermittent faults can feel like a random stumble that comes and goes with heat or vibration.

Can it be driven with a dodgy cam sensor?
Sometimes the car will start and run in a backup mode, but performance and economy suffer, and it can stall or refuse to restart hot. It’s best to sort it promptly to avoid being stranded and to protect the catalytic converter from misfire damage.
