- Diagnosis detects oxygen sensor - regulators running contrary to the adaptation limitation.
- For example: The regulator for bank 1 detects an excessively rich mixture and wants to make it leaner. At the same time, the regulator on bank
2 detects an excessively lean mixture and wants to make it richer. If the oxygen sensors or their signal wires have been exchanged, the detected
bank 1 continues to make the mixture richer and bank 2 continues to make the mixture leaner. Only when both oxygen sensors remain on the
opposing stops for a certain period of time will this fault be recorded.
- Do not use contact spray on the oxygen sensor plug connections as this may cause irreparable damage to the wiring (contamination of the
oxygen sensor via the reference air channel).
