Engine Misfire Codes: Complete Guide
Engine misfires are serious issues that can damage your engine. Here's everything you need to know about misfire diagnostic codes.
Random/Multiple Cylinder Misfire Detected
The engine control module has detected misfires occurring randomly across multiple cylinders. This indicates combustion is not happening properly in one or more cylinders, causing rough engine operation and potential damage.
Cylinder 1 Misfire Detected
The engine control module has detected a misfire specifically in cylinder 1. This means the air/fuel mixture in cylinder 1 is not igniting properly.
Cylinder 2 Misfire Detected
The engine control module has detected a misfire specifically in cylinder 2. This means the air/fuel mixture in cylinder 2 is not igniting properly.
Cylinder 3 Misfire Detected
The engine control module has detected a misfire specifically in cylinder 3. This means the air/fuel mixture in cylinder 3 is not igniting properly.
Cylinder 4 Misfire Detected
The engine control module has detected a misfire specifically in cylinder 4. This means the air/fuel mixture in cylinder 4 is not igniting properly.
