Service Technical Information 96/23 ENU 2473 2 Message “Engine Control Fault” in the Instrument Cluster/Fault Memory Entries for the Oxygen Sensor Downstream of the Catalytic Converter (96/23) Vehicle Type: Panamera 4 E-Hybrid (971) Panamera 4 E-Hybrid Executive (971) Panamera 4 E-Hybrid Sport Turismo (971) Model Year: As of 2017 up to 2023 Equipment: 2.9-liter twin-turbo V6 engine with hybrid drive Concerns: Oxygen sensors downstream of catalytic converter Cause: The message ‘Engine control fault’ is displayed in the instrument cluster and the following entries are stored in the fault memory of the DME control unit: • • • • P227000 - Oxygen sensor downstream of catalytic converter, bank 1 – signal too lean P227200 - Oxygen sensor downstream of catalytic converter, bank 2 – signal too lean P209600 - Oxygen sensor correction downstream of catalytic converter, bank 1 – above lean control limit P209800 - Lambda correction behind catalytic converter, bank 2 – above lean control limit At high ambient temperatures around the oxygen sensors downstream of the catalytic converter, the measuring electrodes may become contaminated over the service life of the vehicle which can lead to a functional impairment of the oxygen sensors and thus to the described fault pattern. Action: If there is a customer complaint on vehicles that were manufactured before the deployment date listed below, replace the oxygen sensors on the catalytic converter and the turbocharger shield. Date of Introduction: Standard use modified turbocharger shield from January 9, 2023. Required parts Part No. Designation – Location Number 00004330438 Oxygen sensor – downstream of catalytic converter 2 pieces PAE119607 Heat shield – Turbocharger 1 piece AfterSales Aug 7, 2023 Page 1 of 3 2 Service 2473 ENU Technical Information 96/23 WHT008539 Hexagon-head bolt with inner multiple-tooth head (Duo) M10 x 80 – Dome strut to body 2 pieces PAF912696 M10 hexagon nut – Dome strut to body 2 pieces N 10664503 Hexagon-head bolt, M8 x 45 – Side strut to body 2 pieces Required tools Tool: • • • • • • • • • 3337 - Ring wrench set for oxygen sensor Torque wrench, 2 – 10 Nm (1.5 – 7.5 ftlb.), e.g. V.A.G 1783 - torque wrench, 2 – 10 Nm (1.5 – 7.5 ftlb.)

Isolate the high-voltage system from the power supply using the PIWIS Tester and complete the relevant documentation Workshop Manual '2X00IN Isolating high-voltage system from power supply/Starting high-voltage system'. Information New oxygen sensors are pre-greased.
