Terms memorize DTC

ECU memorizes the code P0300 and warning light illuminates the engine management system, if the two driving cycles occur Misfire 2 working mix at 100 revolutions of the crankshaft.

The frequency of the misfire is measured every 200 revolutions of the crankshaft under the following conditions:

- The rate of change of the engine speed less than 1000 ^min -1 for the second;

- The engine speed is in the range 600-4000 ^min -1;

- Engine load greater than 2 milliseconds;

- Fuel shut-off does not occur;

- A starter is not working;

- The car moves along a flat road (acceleration sensor detects the acceleration of 0.3 g).

If the frequency of repetition misfire for 200 revolutions of the crankshaft is increased by 5-25%, there is a risk of failure of the catalytic converter, and the lamp failure the engine management system, first lights flashing, and then a constant glow. At a high enough repetition rate of misfire catalyst temperature may reach 1950 ?� C. Memory of the computer code indicates a fault in the ignition circuit of the corresponding cylinder.
