NOTES:
- The engine must not be switched off during the test sequence.
- If the test sequence procedure is interrupted or not followed, the readiness code will not be created.

- Check Diagnostic Trouble Code (DTC) memory. DTC Memory, Mode 3

- Run engine at idle for 40 seconds.

Diagnosis: Heated Oxygen Sensor (HO2S) aging
- Increase engine speed to 2200-3300 RPM for 3 minutes.

Diagnosis: Oxygen Sensor (O2S) control adaptation in partial load range
- Test drive for at least 13 minutes. When doing this:

- Manual transmission: 3rd gear
- Test drive must be carried out without interruption, this means without reaching deceleration fuel cutoff or idle (closed throttle position)

If the readiness code is still not OK, perform the work steps again.
