Parts for your 2016 Toyota Hilux-Throttle position sensors

2016 Toyota Hilux throttle position sensors: what’s fitted and how to look after it

Yes, the 2016 Toyota Hilux uses a throttle position sensor (TPS). Toyota’s Hilux N80 repair information (2015–2020) lists a “Throttle Body with Motor and Position Sensor” on the 2TR‑FE petrol, and a “Throttle Control Motor with Position Sensor” on the 1GD‑FTV/2GD‑FTV diesels. The Toyota Electronic Parts Catalogue also shows the sensor integrated into the throttle body/actuator assembly, and the engine diagnostics include DTCs P0120–P0124 and P2135 for throttle position circuit and correlation faults. So a TPS is definitely relevant on this model.

On the 2016 Hilux, the throttle position sensor tells the engine computer exactly where the throttle plate is. On petrol models it’s part of the electronic throttle body, working with the motor to give smooth drive‑by‑wire control, crisp response, steady idle and sensible fuel use. On diesels, there’s still a throttle valve with a position sensor, even though the engine’s power is mainly managed by fuel injection, the valve and its sensor help with EGR flow, idle stability and gentle shut‑down to avoid shudder. Either way, the ECU watches the TPS constantly to manage fuelling, emissions, and even auto transmission shift behaviour.

As part of regular servicing of a 2016 Toyota Hilux, it’s smart to keep the throttle system clean and the wiring healthy. The TPS itself is sealed and not a serviceable item, so attention goes to the throttle body/actuator and loom. Every 40,000–60,000 kilometres, check the intake for oil mist and dust, ensure the connector is snug and corrosion‑free, and clean the throttle bore and blade with a sensor‑safe throttle cleaner (short, light sprays, no drowning). Avoid forcing the plate open by hand on electronic units. If the gasket is disturbed, fit a new one.

When faults pop up—check engine light, limp mode, surging, hunting idle, poor economy, or codes like P0121/P2135—diagnose first: scan live data for mismatched accelerator vs throttle angles, inspect for vacuum leaks, and confirm good grounds and 5V reference. Replacement on these Hilux models normally means swapping the whole throttle body (petrol) or throttle control motor assembly (diesel). After refit, a throttle/idle learn with a proper scan tool is recommended, many will self‑learn after a short drive, but a guided reset saves time. Always disconnect the battery before unplugging the unit, and verify updates with a road test.

• Typical symptoms of a failing TPS system: hesitant take‑off, erratic idle, harsh or flared shifts (auto), black smoke on some diesels, and stored TPS correlation codes.
• Parts vary by VIN, confirm the exact engine and spec before ordering.

FAQs

Does a 2016 Hilux diesel have a throttle position sensor?
It does. The 1GD‑FTV and 2GD‑FTV diesels use a throttle control motor with a built‑in position sensor. It doesn’t control engine power like a petrol butterfly, but it’s key for EGR flow, smooth idle and clean shut‑down. If it goes out of whack, expect a warning light and reduced performance.

Can the TPS be cleaned or calibrated?
The sensor is sealed and not adjustable. Clean the throttle bore with a sensor‑safe cleaner and leave the sensor alone. If replaced, carry out a throttle/idle learn with a scan tool, some ECUs will relearn after a short drive, but a proper reset gives a quicker, more stable result.

What fault codes point to TPS trouble on a 2016 Hilux?
Common ones include P0120–P0124 (TPS circuit range/performance) and P2135 (throttle/pedal position correlation). Pair those with symptoms like limp mode, poor throttle response, or a hunting idle, and it’s time for wiring checks, throttle body cleaning, or component replacement.
