Code P0115 2007 Toyota Camry Description

The P0115 code for a 2007 Toyota Camry specifically relates to the Engine Coolant Temperature Circuit. This code is triggered when the Engine Control Module (ECM) detects a malfunction in the circuit that monitors the engine coolant temperature. The engine coolant temperature sensor is responsible for sending data to the ECM, which uses this information to adjust fuel injection, ignition timing, and other engine functions to ensure optimal performance and fuel efficiency.
