P0217 on Kia
Engine Overtemperature Condition
P0217 on Kia vehicles indicates engine overtemperature condition. Au7o has documented this code across 4 Kia models — most commonly on Seltos, Sorento, Sportage. 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.
Common Causes of P0217
- •Low coolant level or a leak in the cooling system
- •Stuck-closed thermostat
- •Failed water pump
- •Faulty radiator cooling fan or fan circuit
- •Clogged or blocked radiator
- •Faulty coolant temperature sensor giving a false high reading
- •Head gasket failure or combustion gases in the coolant
- •Air pocket in the cooling system after service
P0217 on Kia by Model
Kia Seltos(1 issue)
- Idle Stop & Go Oil Pump Overheating2023-2024
The ISG (Idle Stop & Go) oil pump electronic controller in 2023-2024 Seltos vehicles may contain damaged electrical components that cause the pump to overheat, increasing fire risk. NHTSA Recall 23V-578 covers affected Seltos and Sportage vehicles. Kia replaces the ISG oil pump assembly.
Kia Sorento(1 issue)
- HECU Electrical Short and Engine Compartment Fire Risk2011-2014
The Hydraulic Electronic Control Unit (HECU) in the ABS module can develop an internal electrical short circuit, causing the unit to overheat and potentially ignite an engine compartment fire even while the vehicle is parked. NHTSA Recall 19V-085 covers over 70,000 Sorentos. Kia dealers will replace the HECU fuse and inspect for leaks, replacing the entire HECU assembly if signs of damage are found.
Kia Sportage(2 issues)
- HECU Electrical Short / Fire Risk2012-2016
The Hydraulic Electronic Control Unit (HECU) in the ABS brake module can develop an internal electrical short, causing overheating and potential engine compartment fire. This can occur while driving or while the vehicle is parked. NHTSA Recall 18V-743 and subsequent recalls cover affected Sportages. Kia installs a lower-amperage fuse and inspects the HECU for damage.
- Idle Stop & Go Oil Pump Overheating2023-2024
Certain 2023-2024 Sportage vehicles have an electronic controller in the Idle Stop & Go (ISG) oil pump assembly that may contain damaged electrical components. The damaged components can cause the oil pump to overheat, increasing the risk of a vehicle fire. NHTSA Recall 23V-578 covers affected vehicles. Kia dealers replace the ISG oil pump assembly.
Kia Telluride(1 issue)
- Front Power Seat Motor Overheating / Fire Risk2020-2024
The front power seat motor can overheat if the power seat slide knob becomes stuck, causing the motor to run continuously. This can result in a fire even while the vehicle is parked. NHTSA recall covers approximately 462,869 Tellurides from 2020-2024 model years. Kia dealers install a bracket for the power seat switch back covers and replace the seat slide knobs.

What does P0217 mean on Kia?▼
P0217 stands for "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. On Kia specifically, this code is documented across 4 models.
