ŚredniHeated Oxygen Sensor (HO2S) 1, Bank 1 – Adaptation Error. Manufacturer-specific code used mainly in BMW and Toyota (Prius) vehicles, related to the lambda sensor circuit or fuel injection system.
OBD-II (EN): O2 Sensor Heater Circuit Malfunction Bank 1 Sensor 1
Code P3030 indicates a problem with the adaptation of the heated oxygen sensor (lambda) or a fault in the powertrain input circuit – most often affects BMW and Toyota (Prius) vehicles. The cause could be a faulty lambda sensor, corrosion of electrical connectors, or a problem with the engine management electronics. Professional diagnosis with an advanced OBD-II scanner is recommended.
Symptoms
• Check Engine Light (MIL) on the dashboard • Possible deterioration in engine performance or driving smoothness • Increased fuel consumption • Incorrect operation of the emissions control system • In Toyota Prius hybrids – possible high voltage system fault messages
Possible causes
• Faulty or worn heated oxygen sensor (lambda) bank 1, sensor 1 • Break or corrosion in the lambda sensor wiring harness (heater or signal circuit) • Fault in the engine control unit (ECU/PCM) – incorrect sensor adaptation • Problem with the lambda sensor power supply circuit (fuse, relay) • In hybrid vehicles: fault in the HV battery management module or damage to the high voltage wiring
