September 23, 2020 P0059 Code: HO2S Heater Resistance (Bank 2, Sensor 1)Diagnostic trouble code (DTC) P0059 stands for “HO2S Heater Resistance (Bank 2, Sensor 1).” This code may be set when the vehicle’s powertrain control module (PCM) detects that there is an issue with the heater circuit of the oxygen (O2) sensor. It may also set if the PCM detects a September 23, 2020 P0056 Code: HO2S Heater Control Circuit Bank 2 Sensor 2The PCM determines the oxygen content of the exhaust through heated oxygen sensors in the exhaust system before and after the catalytic converter(s). The data provided by the oxygen sensors helps the PCM maintain the right air-to-fuel ratio.
September 23, 2020 P0050 Code: HO2S Heater Control Circuit Bank 2 Sensor 1Oxygen sensors measure the amount of oxygen in the exhaust. They send data to the vehicle’s PCM, which adjusts the air-fuel ratio accordingly. A conventional oxygen sensor will only send a voltage signal once its tip reaches a temperature of about 527°F.
September 22, 2020 P0005 Code: Fuel Shutoff Valve A Control Circuit/OpenCircuit Open means that there’s a lack of continuity somewhere in the fuel shutoff valve circuit. Causes of open circuits vary, though this type of code could stem from broken wiring, poor connections across electrical connectors or previously repaired wiring, loss of ground that prevents current flow, blown fuses, defective
