P0042 Code: HO2S Heater Control Circuit Bank 1 Sensor 3
P0042 Code: HO2S Heater Control Circuit Bank 1 Sensor 3Bank 1 is the side of the engine where the #1 cylinder is located. P0042 code is set when your car’s PCM determines a potential problem with the heater element circuit of the oxygen sensor.
P0058 Code: HO2S Heater Control Circuit High (Bank 2, Sensor 2)
P0058 Code: HO2S Heater Control Circuit High (Bank 2, Sensor 2)Many oxygen sensors also have a heating element that helps bring the sensor up to operating temperature quicker. These sensors need the heating element because they produce more accurate readings when brought up to a certain temperature. Once the sensors are up to operating temperature, they send exhaust oxygen data
P0080 Code: Exhaust Valve Control Solenoid Circuit High Bank 1
P0080 Code: Exhaust Valve Control Solenoid Circuit High Bank 1On vehicles equipped with variable valve timing (VVT), the PCM can adjust the camshaft position, altering the timing of the exhaust and/or intake valves. The PCM controls the camshaft position by regulating oil flow (via a solenoid) to the actuator(s) mounted on the end of the camshaft(s).
P0411 Code: Secondary Air Injection Incorrect Flow Detected
P0411 Code: Secondary Air Injection Incorrect Flow DetectedAs was mentioned, the secondary air injection system reduces emissions by introducing fresh air into the exhaust system. Older vehicles have a belt-driven air pump while newer models have an electric pump. Code P0411 may get registered when the amount of air entering the exhaust is not what the powertrain
