Parts for your 2010 Daihatsu Bego-Crank angle sensor

2010 Daihatsu Bego crank-angle sensor — what it does and how to look after it

Yes, the 2010 Daihatsu Bego is fitted with a crank-angle sensor (often listed as a crankshaft position sensor or “NE” sensor). Technical references that document it include the Daihatsu Terios/Bego J200/J210 Workshop Manual (Engine Control – EFI, Crankshaft Position Sensor description/inspection) and Toyota Rush J200E service documentation. These outline the sensor’s role and show its location on the cylinder block near the crankshaft timing pulley. So it’s absolutely relevant to the 2010 Bego’s 1.5‑litre 3SZ‑VE (and market variants with K3‑VE).

This little sensor is the ECU’s timekeeper. It reads the crank’s exact position and speed, letting the engine computer fire the coils and injectors at the right moment, manage VVT‑i timing, and stabilise idle. If the signal goes missing or messy, the Bego can be hard to start, stumble, or not run at all. It’s one of those unseen heroes that keeps things smooth under the bonnet on every school run and weekend mission.

It’s not a scheduled replacement item, but it does benefit from a quick look whenever the front of the engine is being serviced. Check the connector for a snug fit, the wiring for chafing near the crank pulley and splash shield, and make sure there’s no oil weeping onto the sensor nose from the front crank seal. On high‑kilometre Begos, road grit and moisture can creep in, a gentle clean of the connector terminals and fresh dielectric grease helps keep gremlins away.

Replacement is straightforward with basic tools. Disconnect the battery, remove the lower splash guard for access, unplug the two‑pin connector, and undo the retaining bolt. Swap the sensor, lightly oil the O‑ring, refit the bolt (to the workshop manual torque spec), reconnect, and clear any fault codes. No special coding is required, the ECU learns the signal on the fly. After fitting, let the engine warm up and idle for a few minutes, then take a short drive so the ECU can tidy up fuel and idle trims. Stick with quality OE‑equivalent parts (DENSO style) to avoid intermittent faults.

• Common symptoms: long crank/no start, random stalling, misfire at low RPM, dead tacho, and a check engine light with codes like P0335/P0336.
• Good practice: fix frayed loom clips, keep the area clean, and investigate any oil leaks promptly to protect the sensor.

Popular questions

Where is the crank-angle sensor on a 2010 Daihatsu Bego?
It’s mounted on the right-hand side of the engine block facing the crankshaft timing pulley, just behind the lower timing cover area. Access is usually best from the front underside or the right wheel arch after removing the plastic splash guard. You’ll spot a single small retaining bolt and a two‑pin plug.

What are the signs of a failing crank-angle sensor, and can it be driven?
Typical signs include hard starting, sudden stalling, uneven idle, misfire at low speed, and a check engine light (often P0335/P0336). It might run intermittently, then cut out when hot. Driving with a failing sensor risks an unexpected stall, so it’s best to diagnose and sort it sooner rather than later.

Does the Bego need programming after sensor replacement?
No special programming or coding is required. Clear any stored fault codes, warm the engine, and let it idle for a few minutes to allow normal trims to settle. If issues persist, check cam/crank correlation, wiring integrity, and the connector fit.
