Terms of DTC memory (short-term regulation of the composition of the mixture)

ECU memorizes one of the fault codes and includes a warning light engine management system, if within 30 seconds in the two driving cycles, the value of short-term regulation of the mixture changed to 10-15% in the direction of enrichment (for R01123), or if the additional value of short-term regulation less than 0.4 milliseconds, or changes by 10-15% in the direction of depletion under the following conditions:

- ECU operates in a closed loop control;

- The frequency of engine speed below 1000 ^min -1;

- Coolant temperature is above 70 ?� C;

- Canister purge system does not work;

- Air mass flow rate is less than 7.5 g / s (R01123), or 5.5 g / s (R1124).
