Oxygen sensor heater circuit behind catalytic converter, implausible signal NOTE The function checks the sensor temperature (by measuring the internal resistance of the Nernst cell) dependent on the exhaust temperature. This is used to reveal deviances between the actual and target temperatures of the oxygen sensor, which implies faulty heater adjustment. Diagnostic conditions DME control module supply voltage 10 V ... 16 V Exhaust temperature 250 °C ... 600 °C Intake air temperature > -7°C no other final stage oxygen sensor heater error Possible fault causes plug corrosion Oxygen sensor faulty DME control module faulty

Coverage and how to read this overview
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.
