KlaroP0300
SEVERERandom/Multiple Cylinder Misfire Detected
What this code means
One or more cylinders misfire irregularly. The engine may shake and lose power, and the catalytic converter can be damaged if the problem persists.
This is the most serious family of the set. A misfire sends unburnt fuel into the exhaust, where it destroys the catalytic converter within a few dozen kilometres. A flashing warning light means a misfire is happening now: stop driving.
How to read this code
- PPowertrain
- 0standardised code
- 3Ignition and misfire
- 00P0300
The letter P names the system: Powertrain. The digit 0 that follows marks a standardised code, shared by all manufacturers code. The next digit, 3, locates the fault: ignition and misfire.
What to do
Have it checked promptly. A misfire sends unburnt fuel into the exhaust and destroys the catalytic converter within a few dozen kilometres. If the light is flashing, stop driving.
Clearing a code switches the light off but repairs nothing: if the fault remains, the code comes back.
