What Does code po303?
What Does the P0303 Code Mean? Diagnostic trouble code (DTC) P0303 stands for “Cylinder 3 Misfire Detected.” The code indicates that the powertrain control module (PCM), has counted enough misfire events on cylinder 3 to store the misfire code for that cylinder.
What is the trouble code for cylinder 3?
All our repairs are backed by our 12-month / 12,000-mile warranty. P0303 is a generic diagnostic trouble code (DTC) indicating an issue with the firing of cylinder 3. This code may be seen with other misfire codes as well as lean / rich condition codes. The P0303 DTC is set when the ECU detects multiple misfires from cylinder 3.
What does p0303 mean on cylinder number 3?
Commonly associated with codes: P0300 What Does P0303 Mean? P0303 indicates that cylinder number 3 is experiencing misfires. A misfire occurs when an insufficient amount of fuel is burning in a cylinder.
What should I do if my p0303 engine misfire?

What to do when cylinder 3 misfire is detected?
When the coil packs fail, they can be slightly different to diagnose. The easiest way is to move the suspected coil pack to another cylinder; if the misfire changes to the new cylinder, then the coil pack is the cause. Coil packs are normally replaced as a set. Need help with a P0303 code?

Where is the spark plug on a cylinder?
A spark plug is located on the top of each cylinder. The spark plug uses an electric spark to ignite the flammable air/fuel mixture, producing energy. The energy released by the fuel combustion powers the crankshaft. All of the cylinders work together to regulate the rotation of the crankshaft.
What causes a cylinder to misfire with a sparkplug?
If the misfire moves with the sparkplug (for example) then the sparkplug would be the cause of the misfire. If switching components to a good cylinder doesn’t eliminate the original misfire then there could be a problem with compression.
