Parts for your 2007 Toyota Hilux-Throttle position sensors

2007 Toyota Hilux throttle-position-sensor (TPS)

Based on technical references — Toyota New Car Features (Hilux AN10/AN20 platforms, 2005–2011), Toyota Repair Manual sections for Engine Control (ETCS‑i, Throttle Body/Throttle Valve), and independent service data (e.g., Autodata, Haynes) — the 2007 Toyota Hilux is fitted with a throttle-position sensor. On the petrol 2TR‑FE (2.7) and 1GR‑FE (4.0 V6), the TPS is integrated into the electronic throttle body (dual-track). On the 2KD‑FTV and 1KD‑FTV diesels, a motorised throttle valve with a position sensor is used to manage EGR flow and smooth shutdown. So a TPS (or throttle valve position sensor) is relevant and used across 2007 Hilux variants.

For a 2007 Hilux, the TPS tells the engine ECU exactly where the throttle plate sits. In the petrol models, it partners with the accelerator pedal position (APP) sensor to deliver crisp throttle response, stable idle, cruise control accuracy, and tidy gear changes on autos. On the diesels, the throttle valve position sensor helps the ECU control EGR flow and ensures gentler engine shutdown, cutting shudder and emissions. If that signal goes skew‑whiff, expect rough idle, flat spots, limp mode, poor fuel economy, or a glowing MIL with codes like P0120, P0220, P2135, or for diesels P2119/P2102.

On most 2007 Hilux engines, the TPS is built into the throttle body, so replacement usually means swapping the whole throttle body assembly. It’s smart to rule out basics first: check the connector for corrosion, make sure the loom isn’t chafed near the throttle body, and verify good battery/charging health. A thorough throttle body clean can restore smooth operation, especially on diesels that soot up from EGR. Use throttle-body-safe cleaner, keep fluids out of the motor housing, and don’t force the plate open by hand on ETCS‑i. Let it dry properly before refitting.

After any throttle body replacement or deep clean, an adaptation/reset is recommended. Using Toyota Techstream (or an equivalent scan tool), perform the throttle valve initialisation/idle learn. If a scan tool isn’t handy, a battery disconnect followed by key‑on and a stable idle period can prompt a relearn, though a scan tool is the tidy way. Replace the gasket if removed, use the correct torque from the workshop manual, clear DTCs, then road test. If symptoms persist, double‑check the APP sensor, look for air leaks, and confirm MAF readings.

Good servicing practice for Aussie and Kiwi conditions is to inspect the throttle body and its wiring every 40–60,000 km, clean as needed, and act early if there’s surging, hesitation, or odd idle behaviour. That keeps the Hilux feeling perky under the right foot and saves drama down the track.

• Common signs to watch: surging, hesitation, erratic idle, poor economy, kickdown weirdness, MIL with TPS/EGR-throttle codes.
• Best tools: quality scan tool for live data and relearn, throttle-body-safe cleaner, new gasket if removed.

Popular questions

Does a 2007 Hilux actually have a throttle-position sensor?
Yes. Petrol models use an electronic throttle body with an integrated dual-track TPS. Diesel 1KD/2KD models use a motorised throttle valve with a position sensor for EGR control and smooth shutdown. It’s a key input the ECU relies on, even though diesels don’t meter engine load with a traditional throttle plate like petrols do.

What are the symptoms of a failing TPS on a 2007 Hilux?
Owners often report flat spots, hunting or high/low idle, harsh shifts on autos, and the MIL on. Fault codes such as P0120–P0123/P2135 (petrol) or P2119/P2102 (diesel) are common. Before condemning the part, check wiring/connectors and consider a careful throttle body clean, particularly on sooty diesels.

Is a relearn needed after cleaning or replacing the throttle body/TPS?
Recommended, yes. Use Techstream (or similar) to run the throttle/idle learn procedure. Without a scan tool, a battery reset followed by a stable idle may help, but a proper adaptation via the tool yields the most consistent result.
