2013 Daihatsu Bego camshaft-sensor: what it does and when to service it

Yes, the 2013 Daihatsu Bego runs a camshaft-sensor. The model uses the 3SZ-VE 1.5‑litre DOHC petrol engine, and factory literature for the J200/J210 series (Daihatsu Service Manual – Engine Control, Toyota Rush J200 Repair Manual, Daihatsu Electronic Parts Catalogue) specifies a camshaft position sensor (CMP) as part of the engine management system. These documents also outline diagnostic trouble codes (like P0340–P0344) tied directly to this sensor, confirming it’s fitted and monitored by the ECU.

On this Bego, the camshaft-sensor works with the crank sensor to tell the ECU exactly which stroke each cylinder is on. That lets the computer fire the injectors sequentially, trigger the coil-on-plug ignition at the right moment, and manage variable valve timing. Get that timing right and the engine starts quickly, idles smoothly, pulls well across the revs, and sips fuel rather than guzzling it. If the signal goes missing or messy, the ECU can fall back to a limp strategy, you’ll see the check engine light, and it may crank longer, stall at idle, or feel doughy under throttle.

• Common symptoms: hard starting or long crank, rough idle, flat spots or reduced power, worse fuel economy, stalling at lights, and fault codes such as P0340/P0341.

There’s no scheduled replacement interval for the camshaft-sensor on the 2013 Daihatsu Bego. It’s a solid-state part and generally “fit and forget.” As part of regular servicing, it’s worth a quick look under the bonnet: check the sensor connector for oil ingress, brittle wiring, or a loose retaining bolt. Keeping up with clean engine oil matters too—sludgy oil around the timing area can contaminate connectors and upset signal quality.

Replacement is straightforward if it does fail. Disconnect the battery, pop off the engine cover, and find the sensor on the timing chain end of the cylinder head (a single retaining bolt and an O‑ring). Swap the O‑ring, seat the sensor cleanly, tighten to the workshop spec, reconnect, then clear any codes. A special “coding” or relearn isn’t typically required on this engine, the ECU will sync the crank and cam signals on the next start. After a test drive, check live data for stable cam/crank correlation and confirm no fresh DTCs appear.

Genuine and quality OEM sensors are available for the 3SZ‑VE. When choosing a replacement, match by engine code and VIN, and don’t forget a fresh O‑ring to keep oil where it belongs.

FAQs

Where is the camshaft-sensor on a 2013 Daihatsu Bego?
It’s mounted on the cylinder head at the timing chain end (under the plastic engine cover). Look for a small, two‑wire or three‑wire sensor held in with a single bolt and sealed by an O‑ring. Access is usually easy with basic hand tools.

Does the camshaft-sensor need programming after replacement?
No. On the Bego’s 3SZ‑VE, the ECU automatically syncs the cam and crank signals. Clear any stored fault codes, start the engine, and take a short drive while monitoring for fresh codes. If correlation faults persist, inspect wiring, connector fitment, and timing chain condition.

Can a dodgy camshaft-sensor cause a no‑start?
It can. A failing sensor may lead to long cranking or intermittent no‑start, plus rough running and poor economy. It usually won’t cause mechanical damage by itself, but ignoring related timing or wiring issues can snowball into bigger headaches, so it’s best sorted promptly.
