  • Faulty Heated Oxygen Sensor (H2OS) Bank 1 Sensor 1
  • Heated Oxygen Sensor (H2OS) Bank 1 Sensor 1 harness is open shorted to ground
  • Heated Oxygen Sensor (H2OS) Bank 1 Sensor 1 circuit poor electrical connection
  • Heated Oxygen Sensor (H2OS) Bank 1 Sensor 1 circuit fuse
  • Faulty Engine Control Module (ECM)
The code means that there is a problem with the heater element circuit of the heated oxygen sensor. Water getting inside the heated oxygen sensor connector can cause the heated oxygen sensor fuse to blow, which is a very common problem for this type of code. Before replacing the sensor, check for the condition of the heated oxygen sensor fuse and connectors.
