2014 Toyota Camry temperature sensors: what they do and how to look after them

Temperature sensors are absolutely fitted to the 2014 Toyota Camry and they’re central to how the car runs. Technical references such as the Toyota Repair Manual for 2014 Camry (Engine Control and Cooling System sections), the Toyota Electrical Wiring Diagram (EWD), and Toyota New Car Features (NCF) detail several: the engine coolant temperature (ECT) sensor, intake air temperature (IAT) sensor, ambient and evaporator temperature sensors for the HVAC, and a transmission fluid temperature sensor in auto models. These feed the ECM/PCM and HVAC controllers, and their data is also available via OBD-II (per SAE J1979) for diagnostics.

The ECT sensor is the headline act. It tells the engine computer how warm the engine is so it can sort cold starts, fuel trim, ignition timing, fan control, and even variable valve timing. The IAT helps the engine adjust for air density, and the transmission temperature sensor guides shift strategy and converter lock-up on the U660E/U760E autos. Ambient and evaporator sensors help the air-con keep the cabin comfy without freezing the evaporator.

• Typical warnings of a crook sensor or circuit include hard cold starts, rich running, rough idle, poor economy, radiator fans that run oddly, erratic temperature gauge, weak A/C, or harsh/late shifts when cold.
• Common fault codes include P0115–P0119 and P0125 (ECT), and P0110 (IAT), as outlined in Toyota diagnostic procedures.

There’s no scheduled replacement interval for these sensors
