Parts for your 2001 Daihatsu Gran move-Throttle position sensors

2001 Daihatsu Gran Move throttle position sensor (TPS)

Yes, the 2001 Daihatsu Gran Move is fitted with a throttle position sensor. Technical references that confirm this include the Daihatsu Gran Move/Pyzar (M201/M211 series) factory workshop manual EFI section, Daihatsu’s electronic parts catalogue for the M2xx models listing a three‑pin TPS on the throttle body, and Autodata engine management diagrams showing a TPS circuit (VTA signal, 5 V reference, sensor earth). Both the 1.5 HC‑EJ and later 1.6 HD‑EP fuel‑injected engines use a cable‑operated throttle with a separate TPS mounted on the throttle body.

The TPS on a 2001 Gran Move tells the ECU exactly how far the throttle plate is opened, so fuelling and ignition timing can match the driver’s right foot. At closed throttle you’ll typically see about 0.5 V, smoothly ramping up to around 4.2–4.5 V at wide open throttle. That smooth sweep is what keeps tip‑in crisp, idle stable, and shifts clean on autos.

As part of regular servicing, it’s worth a quick check of TPS operation if the car shows any of the usual dramas like flat spots, hunting idle, stalling at lights, sluggish take‑off, or the MIL on with codes such as P0120–P0124. Back‑probe the signal wire with the key on, engine off, and open the throttle slowly—voltage should climb steadily with no dead spots. While you’re under the bonnet, clean the throttle body bore and blade with throttle cleaner, but don’t flood the TPS—it's a sealed potentiometer and doesn’t like solvent baths.

Replacement is straightforward for a home mechanic:

• Disconnect the battery (keeps the ECU happy and avoids accidental shorts).
• Remove the intake duct, unplug the TPS, and undo the two mounting screws (they’re small—about 3 N·m, so don’t go gorilla on refit).
• Fit the new sensor with the tang engaged on the throttle shaft, then lightly snug the screws.
• If the mounting is slotted, set closed‑throttle voltage to about 0.5–0.7 V before tightening. If it’s a fixed‑position unit, just install and go.

Finish with an ECU relearn: reconnect the battery, start from cold, let it idle for 5–10 minutes with all loads off, then take a gentle drive for 10–15 minutes. Genuine or quality aftermarket sensors tend to behave best, cheapies can drift or be noisy. A healthy TPS helps the Gran Move feel lively and keeps fuel use and emissions in check—well worth the few extra minutes at service time.

Popular questions about 2001 Daihatsu Gran Move TPS

Where is the TPS located on a 2001 Gran Move?
It’s bolted to the side of the throttle body on the intake manifold, opposite the throttle cable cam. Look for a small black plastic sensor with a three‑pin connector. You can see the throttle shaft running through it—turn the throttle by hand and you’ll see the sensor move with it.

What symptoms point to a failing TPS on this model?
Common signs include a surging or hunting idle, hesitation on take‑off, jerky part‑throttle cruising, higher than normal fuel use, and the check‑engine light with TPS‑related codes. If the voltage doesn’t sweep smoothly or drops out as you open the throttle, the sensor is likely tired.

Does the TPS need calibration after replacement?
If your replacement TPS has slotted mounting holes, yes—set closed‑throttle output to roughly 0.5–0.7 V using a multimeter before tightening. Fixed‑position units don’t need adjustment. After fitting, do an ECU idle relearn and a short drive so the ECU trims settle.
