Fault code P0060 – a step-by-step guide to diagnosing and fixing it

Error code P0060 is displayed and the check engine light is on - what does this mean?

The OBD/EOBD system has detected a fault in the heating circuit of lambda sensor 2 (bank 2). This DTC P0060 indicates a problem with the heating of the oxygen sensor after the catalytic converter, as a result of which the optimum operating temperature is not reached.

What are the possible causes of this error code?

• Defective lambda sensor heater
• Damaged cable to the lambda sensor
• Corroded or loose plug connections
• Blown fuse in the heating circuit
• Defective engine control unit (ECU)
• Short circuit in the wiring
• Overheating of the lambda sensor
• Faulty earth connection

What symptoms occur in parallel with fault code P0060?

• Increased fuel consumption: The vehicle consumes more fuel than usual because the mixture control is not functioning optimally.
• Poor exhaust emission values: Increased emission values are measured during the exhaust emission test.
• Uneven idling: The engine runs unevenly or rough when idling.
• Reduced engine power: Noticeable loss of power, especially when the engine is cold.
• Extended warm-up phase: The engine takes longer to reach operating temperature.

How can the problem with error code P0060 be rectified?

• Repairing fault code P0060 requires a systematic diagnosis of the lambda sensor heater.
• Replacement of the defective lambda sensor bank 2 sensor 2 including integrated heater
• Repair or replacement of damaged cables and plug connections in the heating circuit
• Checking and replacing blown fuses in the lambda sensor heating circuit
• Cleaning corroded contacts and ensuring stable plug connections
• Repairing short circuits or interruptions in the wiring to the lambda sensor
• Checking and repairing the earth connections in the lambda sensor system
