I believe it is the first sensor on the passenger side. but read this also....>P0031 CHEVROLET - HO2S11 Heater Control Circuit Low Voltage....> Possible causes....> - 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 Powertrain Control Module (PCM) Tech notes 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 caused the heated oxygen sensor fuse to blow, which is a very common problem for this type codes. Before replacing the sensor, check for the condition of the heated oxygen sensor fuse and connectors.
