Parts for your 2000 Daihatsu Yrv-Throttle position sensors

2000 Daihatsu YRV throttle-position-sensors

Yes, the 2000 Daihatsu YRV uses throttle-position-sensors (TPS). This isn’t a fringe item either—it’s a core input for the engine control unit. Technical references that list the TPS for the YRV include:

• Daihatsu YRV (M200/M201/M202) Workshop Manual – Engine Control System: details the TPS circuit, ECU pinout (VTA, VCC, E2) and diagnostic trouble codes P0120–P0124.
• Daihatsu K3-VE/K3-VET Engine Training/Technical Data (Denso EFI): explains throttle-angle feedback for fuel and ignition strategies and idle control.
• Autodata/Autoinfo service specs for YRV: notes closed-throttle to WOT sweep voltages (typically ~0.4–0.8 V to ~3.7–4.8 V) and test procedures.

On the 2000 Daihatsu YRV, the throttle-position-sensors tell the ECU exactly how far the throttle plate is open, so it can meter fuel, tweak ignition timing, manage idle speed and handle decel fuel cut. Most non‑turbo K3‑VE models run a cable-operated throttle body with a bolt-on TPS. Turbo K3‑VET variants and some later setups use an electronic throttle body where the TPS is integrated, often as dual tracks for redundancy. Either way, the function is the same—clean signal in, smooth running out.

Owners will usually notice a crook TPS when the car hesitates off the line, hunts at idle, shifts harshly in autos, chews more fuel, or throws a check-engine light with a P012x code. Because the TPS isn’t a scheduled service item, it’s checked or replaced when symptoms crop up or during throttle-body service.

Quick servicing tips for the YRV throttle-position-sensors:

1. Inspect the connector and wiring under the bonnet—green crust or loose pins are common culprits.
2. Clean the throttle body with proper throttle cleaner, avoid drowning the TPS. On cable bodies, clean the plate edges and bore to stabilise idle.
3. Test the TPS: key on, back-probe the signal wire. You want a smooth climb from roughly 0.5 V closed to around 4.5 V at wide open, no flat spots or jumps.
4. If replacing a cable-type TPS, mark the old position and lightly snug the screws (small torque—don’t overdo it). Some units allow minor rotation to set closed-throttle voltage.
5. For electronic throttle bodies (and many turbo models), the TPS is part of the assembly—replace the whole unit, then perform a throttle/idle learn with a scan tool. If a scan tool isn’t available, many YRVs relearn after battery reset and a few minutes of idle without accessories, but the factory procedure is best.

A healthy TPS keeps the YRV feeling perky and predictable in traffic. Given the age of these cars, a quick check of the throttle-position-sensors during routine servicing is a smart, low-cost way to avoid drivability grief.

Popular questions about 2000 Daihatsu YRV throttle-position-sensors

Where is the TPS on a 2000 YRV?
The TPS on cable-throttle K3‑VE models is bolted to the side of the throttle body opposite the cable cam. On variants with electronic throttle, the sensor is built into the throttle body housing, and you won’t see a separate replaceable unit. Either type is accessible under the engine cover near the intake manifold.

Do I need to calibrate the TPS after replacement?
On cable-throttle cars, set the new sensor to achieve the correct closed-throttle voltage and confirm a smooth sweep—some ECUs adapt quickly after a short idle. Electronic throttle bodies typically require a throttle/idle learn via a scan tool to store the new reference positions for accurate control.

What symptoms point to a failing TPS on a YRV?
Common signs include erratic idle, hesitation on take-off, poor fuel economy, sudden surging, and a check-engine light with P0120–P0124 codes. If the auto trans feels clunky on shifts, a dodgy TPS signal can also be the reason, as the ECU shares load data with the transmission control.
