Parts for your 2013 Daihatsu Bego-Crank angle sensor

2013 Daihatsu Bego crank-angle-sensor: purpose, servicing and replacement

Technical documentation for the sister models Daihatsu Terios J200 series and Toyota Rush fitted with the 1.5‑litre 3SZ‑VE engine confirms the presence and use of a crankshaft position sensor (often called a crank‑angle‑sensor). The Daihatsu/Toyota engine repair manuals describe the ECU’s reliance on the NE crank signal from this sensor for ignition timing and sequential fuel injection. Denso engine management training materials covering CKP/CMP inputs also align with this setup. On that basis, the 2013 Daihatsu Bego absolutely uses a crank‑angle‑sensor and it’s a critical piece of the engine control system.

On a 2013 Daihatsu Bego, the crank‑angle‑sensor tracks the crankshaft’s exact position and speed, feeding the ECU the timing info it needs to spark and inject at the right moment. Without a clean signal, starting becomes hit‑and‑miss, fuel economy suffers, and the engine can stumble or stall. Typical tell‑tales of a failing sensor include hard starting (hot or cold), random stalling at idle, uneven idle speed, misfires under load, a dead tacho during crank, and a check engine light with codes like P0335/P0336.

Unlike filters or plugs, the crank‑angle‑sensor isn’t a scheduled replacement item. It should be inspected or replaced if there are driveability issues or relevant fault codes. On the Bego’s 3SZ‑VE, the sensor is usually mounted at the lower side of the engine near the crank pulley or bellhousing, reading a toothed reluctor wheel. Oil contamination, damaged wiring, or metal debris on the sensor tip can distort the signal, so a clean and intact mounting area matters.

• If replacing: disconnect the battery, safely raise the front if needed, unplug the connector, remove the retaining bolt, and withdraw the sensor. Lightly lubricate the O‑ring on the new unit, seat it squarely, refit the bolt, and reconnect the plug.
• Afterwards: clear any stored codes, check live data for a stable RPM signal while cranking, and take a short road test. No coding is typically required, the ECU will use the new signal straight away.

Good practice during regular servicing is to check the harness routing away from heat sources, ensure solid engine earths, and fix any oil leaks that might wick into the connector. When buying a replacement, choose an OEM‑quality sensor—cheap copies can cause intermittent faults that are maddening to diagnose. For vehicles doing lots of short trips around town in Aus or NZ conditions, an occasional visual check under the bonnet helps catch issues before they leave the Bego stranded.

Popular questions about the 2013 Daihatsu Bego crank‑angle‑sensor

Where is the crank‑angle‑sensor located on a 2013 Daihatsu Bego?
It’s typically fitted low on the engine, reading a toothed wheel on the crank—either by the crank pulley at the front or near the transmission bellhousing. Access is usually from underneath or through the left front wheel arch with the liner pulled back.

If space is tight, removing a splash shield helps. Always trace the connector and wiring to confirm the right sensor before removal.

What symptoms point to a failing crank‑angle‑sensor on a Bego?
Hard starting, intermittent stalling, rough idle, sudden power loss, or a dead rev counter while cranking are common. The check engine light may log crank sensor codes (for example, P0335). These symptoms can overlap with cam sensor or wiring faults, so scan‑tool diagnosis is recommended.

Does a new crank‑angle‑sensor need programming?
On the 3SZ‑VE, no special coding is normally required. Fit the sensor, clear any codes, and the ECU will recognise the signal immediately. A brief idle relearn may occur after the battery has been disconnected, which is normal.
