Order of inspection

  1. P0150 O2 Sensor Circuit Malfunction (Bank 2 Sensor 1) Medium

    The P0150 code means the computer found an electrical fault in the bank 2 sensor 1 oxygen sensor circuit. The most common culprits are a damaged connector, wiring burned by the exhaust, or the sensor itself. You can usually keep driving for now, but an upstream fault can raise fuel use and wear out the catalytic converter over time.
