This summary uses the existing diagnostic information shown in full below.
The car's computer is saying that the part that makes the spark for cylinder number 3 is either too hot or not working at all.
This code indicates that the ignition coil for cylinder 3 has been turned off because it got too hot or it stopped sending signals.
The P3317 code is triggered when the Engine Control Module (ECM) detects that the ignition coil for cylinder 3 has been deactivated due to an overtemperature condition or is not sending a signal. This can affect the engine's performance and efficiency.
• Engine misfire
• Rough idling
• Check engine light on
• Faulty ignition coil
• Poor electrical connections
• ECM malfunction
ECM: Engine Control Module
Ignition Coil: A component that transforms the battery's voltage to a higher voltage to create a spark in the engine's cylinders
• Check for any additional codes
• Inspect the ignition coil and wiring for damage
• Test the ignition coil with a multimeter
• Replace the faulty ignition coil
• Repair or replace damaged wiring
• Reprogram or replace the ECM if necessary
• OBD-II scanner
• Multimeter
• Socket set

Engine Performance
• Do not ignore the check engine light
• Have the vehicle inspected by a professional
• Avoid driving long distances until the issue is resolved
Check with the vehicle manufacturer for specific warranty coverage on ignition components.
This code has been associated with ignition coil failures in various vehicle models, often due to overheating or poor electrical connections.
Moderate – It is advisable to address this issue soon to prevent further engine damage.
Driving with a misfiring engine can lead to increased emissions and potential safety hazards.
• Engine at operating temperature
• Vehicle idling
The ignition coil for cylinder 3 is located on the engine, usually near the top of the cylinder head.
Q: Can I drive with a P3317 code?
A: It's not recommended to drive for long periods with this code, as it can cause further engine damage.
Q: How do I know if my ignition coil is bad?
A: Common signs include engine misfires, rough idling, and a check engine light.

Fitment Required · Vehicle-fitment part
Relevant when the fault points toward ignition-coil performance or cylinder-specific ignition issues.
Some ignition faults involve coil performance or cylinder-specific coil problems.
Match the coil to your engine and confirm the failed component before ordering.
View options on AmazonThese parts may be related to this fault category, but a code by itself does not confirm exact fitment or guarantee that replacing a part will solve the problem.
