Quick Answer
High SeverityNot safe to drivePeugeot
P0302 on a Peugeot indicates your engine's computer has detected consistent misfires specifically in cylinder 2. This single-cylinder code narrows the problem to that cylinder's ignition coil, spark plug, fuel injector, or internal compression, making targeted diagnosis significantly easier compared to a random misfire code like P0300.

How to diagnose P0302 on a Peugeot with OBD2
Follow these steps to pinpoint the root cause of P0302:
- Read freeze-frame data and note engine RPM, load, and temperature when the misfire occurred
- Swap the ignition coil from cylinder 2 to a different cylinder. Clear codes and drive. If the misfire code moves to the new cylinder, the coil is faulty
- Inspect the spark plug on cylinder 2 for wear, oil fouling, or abnormal electrode erosion. Replace if needed
- Test the fuel injector on cylinder 2 using a noid light or by listening for the click pattern with a mechanic's stethoscope
- If spark and fuel are confirmed good, perform a compression test on cylinder 2. Compare results against the manufacturer's specification and other cylinders
