Error identification:

Deviating value from lambda sensor T154.

Cause:

Possible causes:

• The pumping current adaptation for the lambda sensor T154 has reached its maximum permitted value.

• There is a fault in the lambda sensor T154 or its harness-to-harness connectors or electrical cables.

Notes:

The engine s torque is reduced to protect the engine.

Action:

1. Check whether the pumping current adaptation for the lambda sensor T154 has reached its maximum permitted value. Run the Pumping current adaptations wizard.

2. Check the lambda sensor T154 and its harness-to-harness connectors and cable harness.

3. Renew lambda sensor T154.
