Parts for your 2016 Daihatsu Bego-Camshaft sensor

2016 Daihatsu Bego camshaft sensor — what it does and how to look after it

Technical sources confirm the 2016 Daihatsu Bego uses a camshaft position sensor. The Daihatsu J200/J210 service information and Electrical Wiring Diagram list a “Camshaft Position Sensor (G)” feeding the ECM on K3-VE and 3SZ-VE engines, and the Toyota Rush/Bego engine control documentation for 3SZ-VE describes G and NE signals (cam and crank) used for sequential injection, ignition timing and VVT-i control. That means the camshaft sensor is very much relevant to this model.

On this Bego, the camshaft sensor tells the engine computer exactly where the intake cam is sitting, so it can fire injectors in the right order, time the spark properly, and command VVT-i. When it’s healthy, owners get clean starts, smooth idle, tidy fuel economy and fewer emissions. Under the bonnet it’s typically mounted on the cylinder head (intake side), secured with a single bolt and sealed by an O-ring.

It’s not a routine replacement item, but it does appreciate a bit of attention at service time. During scheduled services, it’s smart to inspect the sensor connector for oil wicking, brittle insulation or loose terminals, and to check for rocker cover leaks that can contaminate the plug. Keeping up with oil changes helps too, sludgy oil can affect cam timing and trigger correlation faults that look like a sensor drama.

• Tell-tale signs of a failing cam sensor: longer crank times, rough idle, flat spots, worse fuel use, and the check-engine light with codes like P0340/P0341. Sometimes the car may drop into limp mode.
• Quick replacement tips: disconnect the battery, unplug the sensor, remove the single retaining bolt, twist and pull the sensor out, lightly oil the new O-ring, seat it squarely, and tighten the bolt to spec. Clear any fault codes and perform an idle relearn if needed.

If faults persist after fitting a new sensor, a stretched timing chain or damaged reluctor may be the real culprit, so a cam/crank correlation check with scan data is worth doing. Use a quality OEM-equivalent sensor, cheapies can be fussy about signal quality and heat. Done right, the Bego’s cam sensor should run happily for heaps of kilometres without fuss.

Popular questions about the 2016 Daihatsu Bego camshaft sensor

Where is the camshaft sensor located on a 2016 Bego?
It’s mounted on the cylinder head, typically on the intake side near the front under the plastic engine cover. Look for a small, barrel-shaped sensor with a single 10 mm bolt and a two- or three-pin connector. Access is usually straightforward with basic hand tools.

Can the Bego be driven with a camshaft sensor fault?
It may start and run but can hesitate, use more fuel, or drop into limp mode. Short trips to a workshop are usually fine, but there’s a risk of stalling and poor performance. Best to get it scanned and sorted sooner rather than later.

Does the camshaft sensor need regular replacement?
No scheduled replacement is specified. Replace only if it’s faulty or contaminated. During routine services, inspect the wiring and connector, check for oil leaks at the rocker cover, and make sure the O-ring on the sensor isn’t weeping.
