Parts for your 2013 Toyota Hilux-Throttle position sensors

2013 Toyota Hilux throttle position sensor (TPS) — what it is and how to look after it

Referencing Toyota’s Genuine Repair Manual (TIS) for the 2011–2015 Hilux and the Toyota Electronic Parts Catalogue, the 2013 Hilux does use a throttle position sensor. On petrol variants (2TR‑FE 2.7L and 1GR‑FE 4.0L), the TPS is built into the electronic throttle body (ETCS‑i). On D‑4D diesels (1KD‑FTV and 2KD‑FTV), there’s an electronically controlled intake throttle valve used for EGR management and smooth shutdown, and that assembly includes a position sensor. In all cases, the sensor is integral to the throttle/throttle valve unit rather than a separate, screw‑on item.

The TPS tells the engine ECU exactly where the throttle plate sits. On petrol Hilux models, that signal helps the ECU meter fuel, manage ignition timing, control cruise and traction, and coordinate auto transmission shifts. On the D‑4D diesels, the ECU uses the throttle valve position to fine‑tune EGR flow, stabilise idle and shut the engine down cleanly, which keeps things smooth and reduces rattles under the bonnet.

It’s not a scheduled service item, but it does appreciate a bit of care. During routine servicing, it’s smart to:

• Inspect the throttle body/valve connector for corrosion, moisture or loose pins.
• Check the loom for rub‑through near the intake and along the rocker cover.
• Clean the throttle bore and plate with proper throttle body cleaner (not harsh carb spray). Don’t soak the sensor or force the plate by hand.

If faults crop up, the ute might hesitate, idle roughly, drop cruise control, go into limp mode, or light the MIL. Common codes include P0120–P0124, P0220–P0223 and P2135/P2138 (sometimes pointing to the accelerator pedal sensor, which can be confused with the TPS during diagnosis). Always scan it first, check live data for smooth throttle angle change, and rule out wiring issues.

Replacement on a 2013 Hilux typically means swapping the entire throttle body (petrol) or throttle valve assembly (diesel) because the sensor is integrated. Use a new gasket, torque the fasteners correctly, and avoid overtightening the plastic connector lock. After fitting, perform a throttle/idle learn using a capable scan tool (Toyota Techstream or equivalent). A simple battery reset often won’t complete the adaptation properly. Once warm, let it idle a few minutes, then road‑test for consistent throttle response and stable idle. Given the kilometres many Hiluxes cover in Aussie and Kiwi conditions, keeping water out of connectors and avoiding pressure‑washing the intake area goes a long way to preventing sensor grief.

FAQs

Does a 2013 Hilux diesel have a throttle position sensor?
Yes. The 1KD‑FTV and 2KD‑FTV D‑4D engines use an electronically actuated intake throttle valve with a built‑in position sensor. It isn’t for metering air like a petrol engine, instead it manages EGR flow and smooth engine shutdown. The ECU monitors that position just like a TPS on a petrol throttle body.

Can the TPS be cleaned or does it need replacing?
The sensor itself is sealed and not serviceable. You can clean carbon from the throttle bore and plate with proper throttle cleaner, but if the sensor is faulty or has dead spots in its signal, the fix is to replace the throttle body/throttle valve assembly and carry out a throttle/idle relearn.

What are the common symptoms and fault codes?
Hesitation, erratic idle, poor economy, cruise dropping out, or limp mode are typical. Codes often seen are P0120–P0124, P0220–P0223 and P2135. Always check wiring and the accelerator pedal sensor data to avoid replacing the wrong part.
