Parts for your 2006 Suzuki Sx4-Camshaft sensor

2006 Suzuki SX4 camshaft sensor — does it have one, what it does, and how to look after it

Based on technical sources, the 2006 Suzuki SX4 is fitted with a camshaft position sensor (CMP). The Suzuki factory service manual for the SX4 (covering M15A/M16A petrol and DDiS diesel variants), the Suzuki Electronic Parts Catalogue (listing CMP under P/N series 33220-58Jxx for M16A), and major aftermarket catalogues (NGK/NTK, Denso, Delphi) all identify a CMP on 2006 SX4 engines. It’s used by the engine control module for sequential fuel injection, ignition phasing, and variable valve timing strategies.

In simple terms, the camshaft sensor lets the ECU know exactly where the cam is in its rotation so it can fire injectors and coils at the right moment. On the SX4’s petrol engines, that means clean starts, smooth idle, and decent fuel economy. Lose that clean signal and you’ll cop a long crank, rough running, or a check engine light.

There’s no scheduled maintenance for the CMP itself, but it’s smart to give it a look during regular servicing. It’s mounted on the cylinder head at the timing chain end (under the bonnet, near the cam sprocket area). A quick check of the connector and harness routing goes a long way, especially if the engine has had rocker cover leaks or previous work.

• Common symptoms of a crook cam sensor on an SX4: hard starting, stalling, misfires, poor fuel economy, and an engine light with codes like P0340 or P0341. Sometimes you’ll also see VVT-related codes if the signal is noisy.
• Simple maintenance wins: keep oil leaks sorted so the connector doesn’t get contaminated, make sure the wiring isn’t rubbing on the cover, and seat the sensor’s O-ring properly to avoid seepage.

When replacement’s on the cards, use OE or quality aftermarket parts so the ECU gets a clean, accurate signal. Disconnect the battery, pop the retaining bolt, ease the old sensor out, lightly oil the new O-ring, and refit. Tighten snugly to the spec in the service manual and clip the loom back where it belongs. After refitting, clear any fault codes and, if your scan tool allows, run a cam/crank relearn so the ECU is happy. If issues persist, check the crank sensor and timing chain condition, as a worn chain or damaged reluctor can mimic a bad CMP.

Look after this little sensor and the 2006 SX4 will start crisply and run sweet as, whether it’s a daily city runabout or tackling the odd gravel road across NZ and Oz.

Popular questions about 2006 Suzuki SX4 camshaft sensors

Where is the camshaft sensor on a 2006 Suzuki SX4?
It’s mounted on the cylinder head at the timing chain end of the engine. On the petrol M16A, you’ll find it near the top of the engine by the timing cover. Access is usually straightforward from above once the engine cover (if fitted) is off.

What fault codes point to a bad camshaft sensor on an SX4?
The usual suspects are P0340 (Camshaft Position Sensor Circuit) and P0341 (Camshaft Position Sensor Range/Performance). You may also see VVT or misfire codes if the signal is intermittent. Always check wiring and connectors before condemning the sensor.

Can a 2006 SX4 run with a failed camshaft sensor?
Sometimes it might start after a long crank using fallback logic from the crank sensor, but it can stumble, run rough, or stall. It’s not something to ignore—replace the sensor and sort any wiring issues to avoid being stranded.
