Whenever people have a code that is related to an O2 sensor, they always have to figure out exactly which sensor that it corresponds to (bank 1 & 2 and sensor 1 & 2)….so I created this.

Description of O2 Codes

BANK 1
FRONT (Sensor 1)
P0031 – Heated Oxygen Sensor 1 Heater Low Voltage (Bank 1)
P0051 – Heated Oxygen Sensor 1 Heater High Voltage (Bank 1)
P0130 – Front O2 Sensor Circuit (Bank 1)
P0131 – Front O2 Sensor (Lean) (Bank 1)
P0132 – Heated Oxygen Sensor 1 Circuit High Voltage (Bank 1)
P0133 – Heated Oxygen Sensor 1 Circuit Slow Response (Bank 1)
P0134 – Heated Oxygen Sensor 1 Circuit No Activity Detected (Bank 1)
P0135 – Front O2 Sensor Heater (Bank 1)
P1143 – Heated Oxygen Sensor 1 Lean Shift Monitoring (Bank 1)
P1144 – Heated Oxygen Sensor 1 Rich Shift Monitoring (Bank 1)
P1148 – Closed Loop Control (Bank 1)

BANK 1
REAR (Sensor 2)
P0037 – Heated Oxygen Sensor 2 Heater Low Voltage (Bank 1)
P0057 – Heated Oxygen Sensor 2 Heater High Voltage (Bank 1)
P0137 – Rear O2 Sensor Low Input (Bank 1)
P0138 – Heated Oxygen Sensor 2 Circuit High Voltage (Bank 1)
P0139 – Heated Oxygen Sensor 2 Circuit Slow Response (Bank 1)
P0140 – Rear O2 Sensor High Input (Bank 1)
P0141 – Rear O2 Sensor Heater (Bank 1)
P1146 – Heated Oxygen Sensor 2 Minimum Voltage Monitoring (Bank 1)
P1147 – Heated Oxygen Sensor 2 Maximum Voltage Monitoring (Bank 1)
