The P1343 fault code indicates a misfire in cylinder 1 of the engine.

This misfire is accompanied by fuel cut-off, meaning that fuel supply to the cylinder is temporarily stopped. The Engine Control Module (ECM) monitors the crankshaft for acceleration losses during firing segments to detect this misfire. If the expected period duration is greater than the permissible value, a misfire fault is stored in the ECM’s memory.

Depending on the severity of the misfire, the control unit may illuminate the Service Engine Soon light, cut off fuel to the cylinder, and switch lambda operation to open-loop.

The misfire faults are weighted to determine if they are emissions relevant or catalyst damaging.
