P0217: Engine Overtemperature Condition

Most Reported On
P0217 is an OBD-II diagnostic trouble code meaning “Engine Overtemperature Condition.” This code sets when the engine control module detects that the engine has exceeded its safe operating temperature, meaning the engine is overheating based on the coolant temperature sensor reading. Because excessive heat can warp the cylinder head, blow the head gasket, or seize the engine, the computer flags this condition and may reduce power to protect the engine. It generally indicates a real cooling system problem rather than just a sensor glitch, though a faulty sensor can occasionally cause a false reading. An overheating engine should be stopped as soon as it is safe to avoid serious damage. This code is most commonly reported on 2004-2009 Toyota Prius, 2013-2019 Mazda CX-5, and 2007-2016 GMC Acadia, plus 29 other vehicles, with repair costs ranging from $50 to $5,000.
