2006 Toyota Camry temperature-sensors: what they do and how to look after them

Temperature-sensors are absolutely used on the 2006 Toyota Camry. Technical references such as the Toyota Camry 2006 Repair Manual (Engine Control System), the Toyota Electrical Wiring Diagram (EWD), and OBD-II/SAE J1979 standards all detail the Engine Coolant Temperature (ECT) sensor and related temperature inputs (Intake Air Temperature, transmission fluid temperature, and ambient/evaporator sensors on models with auto A/C). These are core signals for the ECU and HVAC systems, so they’re very much relevant on this model.

On the 2006 Camry (2AZ-FE four-cylinder and V6 variants), the ECT sensor is the star player. It tells the engine computer how hot the coolant is so it can set cold-start enrichment, ignition timing, idle speed, and when to bring the radiator fans on. It also influences automatic transmission shift behaviour and the dash temperature gauge. Other temperature-sensors help fine-tune fuelling (IAT), protect the auto trans, and keep cabin climate control behaving nicely.

There’s no fixed replacement interval for these sensors
