2016 Toyota Land Cruiser Throttle Position Sensor (TPS): Fitment, purpose and servicing

Based on Toyota technical literature for the 200 Series (ETCS‑i section of the Repair Manual for 3UR‑FE petrol and 1VD‑FTV diesel), the Electrical Wiring Diagram, and the model’s OBD fault set (e.g., P0120–P0124 and P2135 for throttle position circuits), the 2016 Toyota Land Cruiser uses a throttle position sensor. It’s integrated into the electronic throttle body (dual sensors, often referenced as VTA1/VTA2), and on the diesel it’s part of the throttle control valve used for EGR and shutdown. The sensor isn’t typically serviced separately, Toyota supplies it as part of the throttle body assembly.

The TPS on a 2016 Land Cruiser quietly keeps the big wagon smooth and tractable. Built into the electronic throttle body, it tells the engine ECU exactly where the throttle plate sits, so fuelling, ignition, idle speed and traction systems can play nicely together. On the 1VD‑FTV diesel, that position feedback also lets the ECU nudge the intake throttle for cleaner EGR mixing and gentler shutdown.

Owners might never think about it—until the dash lights up or the idle turns a bit feral. Common clues of a TPS/throttle body drama include limp‑home, erratic idle, a dead spot on tip‑in, or codes like P0121/P0122/P2135. It pays to differentiate from the accelerator pedal position sensor (that’s on the pedal), but a scan tool makes it clear: the TPS lives at the throttle body and should show a smooth, correlated sweep on VTA1/VTA2.

As part of routine servicing, a light throttle body clean every 60,000–80,000 kilometres helps. Use a proper throttle‑body or MAF‑safe cleaner, avoid soaking the electronics, and don’t force the throttle plate by hand. Check the connector for green crusties and make sure the loom isn’t rubbing on the intake.

When replacement’s needed, it’s usually a complete throttle body/valve assembly with a fresh gasket. After fitting, perform the throttle/idle learn with Toyota Techstream or an equivalent scan tool—battery disconnects don’t reliably reset the zero point. Expect roughly an hour or so of labour, more if access is tight with accessories fitted. On diesels, a sticky throttle control valve can masquerade as an EGR issue, verifying commanded vs actual position on live data saves guesswork.

• Keep battery voltage healthy, low volts can trigger throttle faults.
• If codes persist after cleaning and relearn, don’t chase ghosts—scope or replace the assembly per the workshop manual.

Popular questions about 2016 Toyota Land Cruiser throttle position sensors

Where is the TPS on a 2016 Land Cruiser?
The TPS is built into the electronic throttle body. On the 3UR‑FE petrol it’s mounted at the front of the intake manifold. On the 1VD‑FTV diesel, it’s part of the throttle control valve near the intake/EGR junction. It isn’t a separate bolt‑on sensor.

Can the TPS be calibrated or does it self‑learn?
After replacement—or after a heavy clean—the ECU should be guided through a throttle/idle learn using Toyota Techstream or an equivalent scan tool. Minor trims may self‑learn over time, but a proper reset delivers a stable idle and crisp response.

Can the TPS be replaced without changing the throttle body?
On this model, the TPS is integrated and generally not serviced independently. If the sensor has failed or correlation codes won’t clear, the repair is to replace the throttle body/throttle control valve assembly with a new gasket, then perform the learn procedure.
