P0217 on Honda
Engine Overtemperature Condition
P0217 on Honda vehicles indicates engine overtemperature condition. Au7o has documented this code across 2 Honda models — most commonly on Civic, CR-V. 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. Typical repair costs on Honda range from $150 to $8,000, depending on the specific model and root cause.
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 Honda by Model
Honda Civic(2 issues)
- 1.5T Turbo Engine Coolant Intrusion Into Cylinders / Head Gasket Degradation (Class Action)2016-2022
A class-action lawsuit (filed in U.S. and Canadian courts) alleges the turbocharged 1.5L i-VTEC engine cannot properly manage the added compression and heat, so engine coolant seeps through grooves in the cylinder head, degrades the head gasket, and leaks INTERNALLY into the combustion chambers. This is distinct from external turbo coolant/oil-line leaks: here coolant ends up in the cylinders or mixed with oil, causing misfires, internal corrosion, overheating, head-gasket failure and premature engine wear. Reported across 2016-2022 Civic (and shared CR-V/Accord). Plaintiffs allege Honda knew internally since ~2017 but denied warranty repairs.
- 8th-Gen 1.8L Cracked Engine Block — Coolant Leak and Overheating (R18 Casting Defect)2006-2009
A casting/manufacturing defect in the R18 1.8L engine block causes the cylinder block to crack — typically on the back of the block beneath the oil/air separator, in the PCV-system area. The crack lets coolant slowly seep out (and into the PCV system), so the car loses coolant with no visible external puddle at first, then overheats and can be destroyed if driven. CarComplaints documents 63 complaints on the 2008 model year alone, and Honda issued TSB 10-048 plus a 10-year warranty extension to replace affected short blocks. Most owners discover the problem (often only 80k-145k miles) after the extension expired. Distinct from the modern 1.5T turbo coolant issues — this is the naturally-aspirated 8th-gen block.
Honda CR-V(1 issue)
- Navigation/Infotainment Hard Drive Failure (4th Gen)2012-2016
The 4th generation CR-V (2012-2016) EX-L Navigation and Touring models use an internal hard drive-based navigation system (DVD-based maps). The hard drive unit fails, causing navigation system to not load maps, display blank screens, or show outdated maps that cannot update. The HDD unit overheats in summer conditions and develops read errors. Honda issued no formal recall, but some dealerships replaced units under goodwill. Map updates (when hard drive works) cost $250-300 and must be done at dealer. Many CR-V owners prefer switching to Apple CarPlay/Android Auto aftermarket units to avoid this limitation.

What does P0217 mean on Honda?▼
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 Honda specifically, this code is documented across 2 models.
