What does code P2346 mean?

Q: What does code P2346 mean?

Cylinder #11 Above Knock Threshold. P2346 indicates that the engine control module has detected an excessive knock signal specifically from cylinder number 11, meaning that cylinder is producing vibration or noise above the calibrated knock threshold. The computer uses a knock sensor (or a combination of sensors) to identify which cylinder is knocking, and it sets this code when the signal from cylinder 11 exceeds the allowed limit, often leading to retarded ignition timing to protect the engine.
