Parts for your 2014 Daihatsu Bego-Camshaft sensor

2014 Daihatsu Bego camshaft sensor: what it does and when to replace it

Technical sources confirm the 2014 Daihatsu Bego is fitted with a camshaft position sensor. The Daihatsu/Toyota J200-series workshop literature for the Terios/Bego/Rush with the 3SZ-VE (1.5L) and K3-VE (1.3L) engines specifies a Camshaft Position Sensor (CMP) on the cylinder head, and includes diagnostic codes such as P0340/P0341 for the CMP circuit. OEM parts catalogues (Daihatsu EPC and Toyota EPC) list a CMP for these engines, and common service data sets (e.g., Autodata/HaynesPro) show timing and sequential injection strategies that rely on both crankshaft and camshaft signals. So yes—this model uses a camshaft sensor.

The camshaft sensor on a 2014 Daihatsu Bego keeps the engine timing sharp as a tack. It tells the ECU exactly where the cam is in its rotation, so the system can sync fuel injection, coil firing, and variable valve timing. That tight coordination helps it start quickly, run smoothly, and sip rather than slurp fuel. If the signal goes missing or messy, the ECU can’t phase everything properly and the Bego can feel flat, hard to start, or throw a check engine light.

There’s no scheduled replacement interval for the cam sensor—it's a fit-and-forget item until symptoms or fault codes turn up. As part of regular servicing, a quick visual check under the bonnet goes a long way: make sure the connector is seated, the wiring isn’t rubbed through near the cylinder head, and there’s no oil weeping into the plug. On older vehicles, heat and vibration can loosen terminals or harden the loom, so a gentle wiggle test and a dab of dielectric grease on the connector pins (not the sensor face) helps maintain a clean signal.

Common signs it’s time to test or replace the CMP include:

• Long cranking, rough idle, misfires, or sudden loss of power
• Fuel economy dropping off and hesitation on take-off
• Check engine light with codes like P0340/P0341

Replacement is straightforward for a competent home mechanic with basic tools: disconnect the battery, unplug the sensor, remove the retaining bolt, swap the sensor and O-ring, and torque the bolt to spec per workshop data. Keep the mounting face spotless—grit can skew the air gap and signal. If a new sensor doesn’t sort it, inspect the loom back to the ECU and verify the crank sensor too, because the ECU needs both signals to play nice. After refitting, clear any codes and take it for a short drive so the ECU can relearn. For anyone unsure, a trusted workshop can test the waveform and confirm the fix without guesswork.

Popular questions about 2014 Daihatsu Bego camshaft sensors

Where is the camshaft sensor on a 2014 Daihatsu Bego?
It’s mounted on the cylinder head, typically at the front or side near the camshaft gear under the plastic engine cover. Access is from the top of the engine bay. Look for a small two- or three-pin sensor secured by a single bolt with a short wiring pigtail.

Is it safe to drive with a bad camshaft sensor?
The car may still run, but starting can be hit-and-miss and performance can be patchy. Prolonged driving with a failing CMP can cause poor fuel economy and misfires, and may mask other timing issues. It’s best to diagnose and repair promptly.

How much does replacement usually cost in AU/NZ?
As a ballpark, an aftermarket sensor often lands around AUD/NZD $60–$180, with 0.5–1.0 hour labour depending on access. Expect a typical total of roughly $150–$350, varying by brand choice and workshop rates.
