2015 Toyota Land Cruiser Temperature Sensors

Based on Toyota’s factory service literature (Toyota TIS repair manual and Electrical Wiring Diagram for the 200 Series, 2015 model year) and standard OBD‑II diagnostics, temperature sensors are absolutely fitted to the 2015 Toyota Land Cruiser. The manuals document Engine Coolant Temperature (ECT) and Intake Air Temperature (IAT) circuits, evaporator and ambient temperature sensors for climate control, transmission fluid temperature sensing, and—on the 1VD‑FTV diesel—exhaust gas temperature (EGT) sensors for emissions control. Common Toyota DTCs such as P0115–P0119 (ECT range/performance) and P0125/P0128 (coolant temperature/thermostat performance) further confirm their presence and role.

On a 2015 Land Cruiser (both 3UR‑FE petrol V8 and 1VD‑FTV diesel V8 in ANZ), temperature sensors feed the ECUs with live data so the vehicle can warm up cleanly, deliver good fuel economy, protect the engine and gearbox, and keep the cabin comfy. If they go out of whack, the vehicle can overfuel, shift strangely, or overheat without a proper warning.

• Engine Coolant Temperature (ECT): Core input for fueling, ignition timing, idle speed, fan control, and overheat protection.
• Intake Air Temperature (IAT, typically integrated in the MAF): Adjusts fueling and spark for air density.
• Transmission Fluid Temperature: Manages shift strategy and thermal protection.
• Ambient and Evaporator Temperature: Drives the climate control logic.
• Diesel EGT (1VD‑FTV): Guides DPF protection and regen behaviour.
