2006 Daihatsu Terios Camshaft Sensor — What It Does and How to Look After It

Referencing manufacturer documentation and reputable technical guides, the 2006 Daihatsu Terios is fitted with a camshaft position sensor (often called a cam sensor or CMP). Sources include the Daihatsu Terios J200/J210 Engine Control System manual (3SZ-VE), the Daihatsu K3-VE engine service manual used in late first-gen Terios models, and Toyota/Daihatsu EWDs listing the “Camshaft Position Sensor (G2)” and related DTCs (e.g., P0340/P0341). These documents outline the CMP’s role in timing, sequential injection, and intake VVT-i control on both K3-VE and 3SZ-VE engines found around the 2006 model year.

On the 2006 Terios, the camshaft sensor tells the ECU exactly where the intake cam is, so it can fire the injectors at the right moment and trim the VVT-i for smooth torque and clean emissions. It works alongside the crank sensor, the crank provides engine speed and base timing, while the cam sensor adds which stroke each cylinder is on. Without a good CMP signal, the Terios can crank longer, run rough, or drop into a limp strategy with the check engine light glowing.

Owners will usually notice a dodgy cam sensor through tell-tale behaviours and fault codes. Common symptoms include:

• Hard starting, misfires at idle, flat spots under load
• Sluggish performance and higher fuel use as VVT-i backs off
• Check engine light with codes like P0340/P0341

There’s no set replacement interval for the CMP on a Terios, it’s typically a replace-on-failure item. As part of regular servicing, it’s smart to:

• Inspect the sensor connector under the bonnet for oil weep, dust, or loose pins
• Check the engine harness where it runs across the head for chafe
• Clean light contamination with contact cleaner and ensure a snug fit

If replacement is needed, it’s a straightforward job on the cylinder head near the timing chain area. Use a quality sensor to avoid signal noise, lightly oil the O-ring, torque the retaining bolt to spec, and clear fault codes. After refitting, a quick road test and scan data check (cam/crank sync and VVT-i advance) confirms all’s sweet. Keeping the engine oil fresh also helps VVT-i response, making the CMP’s job easier and the Terios happier on Kiwi and Aussie roads.

Popular questions about 2006-Daihatsu-Terios camshaft-sensor

Where is the camshaft sensor on a 2006 Terios?
It’s mounted on the cylinder head, typically at the front near the timing chain area. With the engine cover off, the sensor’s small body and single retaining bolt are easy to spot, and the plug exits toward the engine loom. Access is usually simple with basic hand tools.

Can a faulty cam sensor cause poor fuel economy on a Terios?
Yes. When the CMP signal is unreliable, the ECU may disable or limit VVT-i and switch to less precise fuel timing. That can lead to lazier throttle response, slight misfires, and more fuel burned per kilometre. Fixing the sensor or wiring generally restores economy and smoothness.

Do I need to replace the cam sensor as preventative maintenance?
Not typically. It’s not a scheduled item. Routine checks of the connector and loom during services, plus timely oil changes, are usually all that’s needed. Replace the sensor only if faults, symptoms, or test results point to it.
