P0313 Code: Causes, Symptoms, Diagnosis & How to Fix It
What Does P0313 Mean? P0313 means “Misfire Detected With Low Fuel.” It is a generic OBD2 powertrain trouble code indicating that the engine computer detected a misfire while the fuel level or fuel delivery condition was low. Unlike cylinder-specific codes such as P0301 or P0312, P0313 does not identify one particular cylinder. The problem may occur because the fuel level becomes low enough for the fuel pump to have difficulty maintaining consistent fuel delivery. However, P03


P0312 Code: Causes, Symptoms, Diagnosis & How to Fix It
What Does P0312 Mean? P0312 means “Cylinder 12 Misfire Detected.” It is a generic OBD2 powertrain trouble code that indicates the engine computer has detected a misfire in cylinder 12. The code identifies the affected cylinder but does not automatically identify the failed component. Cylinder 12 is found only on engines with enough cylinders, and cylinder numbering varies between engine designs. Always confirm the cylinder location using the vehicle's service information befo


P0311 Code: Causes, Symptoms, Diagnosis & How to Fix It
P0311 means “Cylinder 11 Misfire Detected.” It is a generic OBD2 powertrain trouble code indicating that the engine computer has detected a misfire involving cylinder 11. The code identifies the affected cylinder, but it does not identify the failed component. Cylinder 11 is found only on engines with enough cylinders, and cylinder numbering varies by engine design. Always use the vehicle's service information to confirm the location of cylinder 11 before testing components.


P0310 Code: Causes, Symptoms, Diagnosis & How to Fix It
The P0310 code means Cylinder 10 Misfire Detected. This generic OBD2 trouble code is stored when the engine computer detects that cylinder 10 is not firing properly. The code identifies the affected cylinder, but it does not identify which component caused the misfire. Possible causes include ignition problems, fuel-delivery issues, intake leaks, low compression, wiring faults, or engine timing problems. The exact diagnostic procedure can vary by vehicle. Cylinder numbering d


P0309 Code: Causes, Symptoms, Diagnosis & How to Fix It
The P0309 code means Cylinder 9 Misfire Detected. This generic OBD2 trouble code is triggered when the engine computer detects that cylinder 9 is not firing correctly. The code identifies the affected cylinder, but it does not identify the failed component. Possible causes include ignition problems, fuel-delivery issues, intake leaks, poor compression, wiring faults, or engine timing problems. Cylinder numbering varies between engine designs, so use the manufacturer's service


P0308 Code: Causes, Symptoms, Diagnosis & How to Fix It
The P0308 code means Cylinder 8 Misfire Detected. This generic OBD2 trouble code is triggered when the engine computer detects that cylinder 8 is not firing properly. P0308 identifies the affected cylinder, but it does not tell you which component caused the misfire. Possible causes include ignition problems, fuel-delivery issues, intake leaks, low compression, wiring faults, or engine timing problems. Cylinder numbering varies by engine design, so use the manufacturer's serv


P0307 Code: Causes, Symptoms, Diagnosis & How to Fix It
The P0307 code means Cylinder 7 Misfire Detected. This generic OBD2 trouble code is triggered when the engine computer detects that cylinder 7 is not firing properly. P0307 identifies the affected cylinder, but it does not identify the failed component. The problem can involve the ignition system, fuel delivery, air intake, engine compression, wiring, or engine timing. The exact location of cylinder 7 depends on the engine design, so use the vehicle manufacturer's service inf


P0306 Code: Causes, Symptoms, Diagnosis & How to Fix It
The P0306 code means Cylinder 6 Misfire Detected. This generic OBD2 trouble code is stored when the engine computer detects that cylinder 6 is not producing combustion correctly. The code identifies the affected cylinder, but it does not identify the failed part. Possible causes include ignition, fuel delivery, air intake, compression, wiring, or engine timing problems. Cylinder numbering varies between engines, so always use the vehicle's service information to locate cylind


P0305 Code: Causes, Symptoms, Diagnosis & How to Fix It
The P0305 code means Cylinder 5 Misfire Detected. This generic OBD2 trouble code is set when the vehicle's engine computer detects that cylinder 5 is not firing correctly. A misfire occurs when combustion inside the cylinder is incomplete, inconsistent, or does not occur as expected. P0305 identifies the affected cylinder, but it does not tell you which component has failed. The problem may come from the ignition system, fuel delivery, air intake, engine compression, wiring,


P0304 Code: Causes, Symptoms, Diagnosis & How to Fix It
The P0304 code means Cylinder 4 Misfire Detected. Your vehicle's powertrain control module (PCM) has detected that cylinder 4 is not firing correctly. A misfire occurs when combustion does not happen properly or consistently inside the cylinder. P0304 identifies the affected cylinder, but it does not automatically identify the failed component. The problem could involve the spark plug, ignition coil, fuel injector, intake system, engine compression, wiring, timing, or another


P0303 Code: Causes, Symptoms, Diagnosis & How to Fix It
The P0303 code means Cylinder 3 Misfire Detected. Your vehicle's powertrain control module (PCM) has detected that cylinder 3 is not firing correctly. A misfire occurs when combustion in a cylinder does not happen properly. P0303 identifies the affected cylinder, but it does not automatically mean a specific part has failed. The problem can involve the spark plug, ignition coil, fuel injector, air intake, engine compression, wiring, or another engine-management component. The


P0302 Code: Causes, Symptoms, Diagnosis & How to Fix It
The P0302 code means Cylinder 2 Misfire Detected. Your vehicle's powertrain control module (PCM) has detected that cylinder 2 is not firing correctly. A misfire occurs when combustion in a cylinder is incomplete or does not occur as expected. P0302 identifies the affected cylinder, but it does not automatically identify the failed part. The cause could involve the ignition system, fuel delivery, air intake, engine compression, wiring, or other engine-management components. Th
