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.

P0300 High

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.
P0301 High

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.
P0302 High

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.
P0303 High

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.
P0304 High

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.
P0305 High

Cylinder 5 Misfire Detected

The engine control module has detected a misfire specifically in cylinder 5. This applies to engines with 5 or more cylinders.
P0306 High

Cylinder 6 Misfire Detected

The engine control module has detected a misfire specifically in cylinder 6. This applies to V6 and larger engines.
P0307 High

Cylinder 7 Misfire Detected

The engine control module has detected a misfire specifically in cylinder 7. This applies to V8 and larger engines.
P0308 High
