Error code P2317 indicates a problem with the secondary circuit of ignition coil F. This means the engine control module (ECM) has detected an electrical fault in the coil that fires spark plug number 6 (on most engines). Driving with this code can cause misfires, poor fuel economy, and catalytic converter damage. The fix typically involves testing and replacing the ignition coil.

Frequently Asked Questions

What does error code P2317 mean?
P2317 indicates a problem with the secondary circuit of ignition coil F. This means the engine control module has detected an abnormal electrical signal from the coil that fires the spark plug.
Can I drive with a P2317 code?
It is not recommended. Driving with a misfire can damage the catalytic converter and reduce fuel efficiency. Address the issue promptly.
What causes P2317?
Common causes include a faulty ignition coil, damaged spark plug, wiring issues, or a failing ECM. Corroded connectors or poor ground connections can also trigger the code.
How much does it cost to fix P2317?
Replacing an ignition coil typically costs $50–$200 for the part and $80–$150 for labor if done by a mechanic. DIY parts can be $20–$100.
Is P2317 the same as a misfire code?
Not exactly. P2317 is specific to the secondary circuit. It will often be accompanied by misfire codes like P0306 (cylinder 6 misfire) but can occur alone.
