2015 Toyota Prius temperature-sensors

Temperature sensors are definitely used on the 2015 Toyota Prius. Toyota’s Repair Manual for the 2ZR-FXE engine documents the Engine Coolant Temperature (ECT) sensor and its diagnostics (e.g., ECT circuit checks and DTCs), the New Car Features (NCF) manual for the ZVW30 Prius details multiple High Voltage (HV) battery temperature sensors feeding the battery ECU to control cooling, and the Electrical Wiring Diagram (EWD) shows the intake air temperature (within the MAF), ambient/outside air sensors, and A/C evaporator temperature inputs. These factory sources make it clear the Prius relies on a network of temperature inputs to manage engine operation, battery life, and cabin comfort.

On a 2015 Prius, temperature sensors quietly keep everything on song. The ECT tells the engine ECU how warm the 1.8-litre hybrid engine is, shaping fuel delivery, ignition timing, idle speed, and when the engine can shut off smoothly in traffic. Intake and ambient temperature readings fine‑tune fuelling and climate control, while the A/C evaporator sensor keeps the cabin cool without icing up the core. The hybrid battery pack uses multiple thermistors to watch cell temperatures
