Parts for your 1996 Daihatsu Gran move-Crank angle sensor

1996 Daihatsu Gran Move crank-angle sensor — what it does and how to look after it

Based on factory literature for the Daihatsu Pyzar/Gran Move G303/G313 series (1996 ignition system sections) and Daihatsu’s Electronic Parts Catalogue for the same models, the 1996 Daihatsu Gran Move uses a crank-angle sensor. It’s integrated inside the distributor rather than mounted separately at the crank pulley. Technical training material across late‑90s Daihatsu EFI systems also describes the distributor’s internal NE/G pickups providing the ECU with both engine speed and position, which confirms the crank-angle sensing function is present on this model.

On the 1996 Gran Move, the crank-angle sensor’s job is to tell the ECU exactly where the crankshaft is and how fast it’s spinning. With that info, the ECU fires the ignition and times fuel injection properly, keeping the little MPV running sweet as and meeting emissions. Because the sensor lives inside the distributor, it’s protected, but heat and age can still take their toll.

When a crank-angle sensor starts to go flaky, owners might notice hard starting, random stalling at lights, rough idle, hesitation under load, or a no‑spark, no‑start situation. The check engine lamp may light up, and a scan tool or blink code reader can show a loss of engine speed/position signal. Before replacing anything, it’s worth checking the distributor cap and rotor for wear, the loom plug for corrosion, and that the earths and battery voltage are solid.

If replacement is needed, the usual approach is to fit a quality distributor assembly that includes the internal sensor, since service parts for the sensor alone can be scarce. A competent DIYer can manage the job at home:

• Mark the distributor’s position relative to the head before removal to preserve base timing.
• Disconnect the battery, unplug the harness, remove the hold-down bolts, and lift the unit clear.
• Install the new distributor aligned to the marks, snug the bolts, reconnect, and start the engine.

After installation, check base ignition timing with a timing light following the workshop procedure for the Gran Move (bridge the diagnostic connector as specified in the manual to fix timing). Use a light smear of dielectric grease on the connector, ensure the cap and rotor are fresh, and keep the timing belt and drive belts in good nick—vibration and heat are the sensor’s enemies. For Aussie and Kiwi conditions, a quick inspection of the distributor and plug at every 10,000–15,000 km service helps catch issues before they strand anyone on the side of the road.

Popular questions

Where is the crank-angle sensor on a 1996 Daihatsu Gran Move?
It’s built into the distributor at the end of the camshaft, not a separate sensor down by the crank pulley. Access is under the bonnet on the cylinder head—look for the distributor with the multi-pin plug.

What are the signs the crank-angle sensor is failing?
Hard starting, intermittent stalling, sudden loss of spark, uneven idle, and surging are common. The check engine light can appear, and a scan may show a missing engine speed/position signal. Always inspect the cap, rotor, and wiring before condemning the sensor.

Can the sensor be replaced on its own, or does the whole distributor need changing?
On many Gran Move distributors, the sensor is integral. While it’s sometimes possible to source the internal pickup, most workshops replace the complete distributor for reliability and to avoid mucking about with delicate internals.
