P0453 2001 Toyota Highlander Code - EVAP System Pressure Sensor/Switch High Input
Quick Answer
The P0453 code for a 2001 Toyota Highlander indicates a problem with the EVAP (Evaporative Emission Control) system pressure sensor/switch, specifically a high input signal being detected. Common causes include Faulty EVAP Pressure Sensor/Switch: The sensor itself may be malfunctioning and providing incorrect readings to the vehicle's computer, EVAP System Leak: A leak in the EVAP system can cause pressure to build up, triggering the high input signal, Purge Valve Stuck Open: If the purge valve is stuck open, it can allow excess fuel vapors to enter the system, leading to increased pressure. Severity is Low - monitor the vehicle and repair when practical. The vehicle can usually be driven if no severe symptoms are present, but symptoms should be checked before extended driving.
