OBD-II Trouble Code Description for P0042 Hyundai
HO2S Heater Control Circuit
What does this mean?
OBD2 Code P0042 Hyundai definition:
Oxygen Sensors (O2S) or Heated Oxygen Sensors (HO2S) need to reach a minimum operating temperature of 750 degrees F to produce an accurate voltage signal. The faster the heated oxygen sensor reaches that temperature the faster the sensor will start sending an accurate signal to the Engine Control Module (ECM). In order to achieve the require temperature, a heater element is included inside the heated oxygen sensor. The ECM controls the heated oxygen sensor heater element based on signals from the engine coolant temperature and engine load. The ECM controls the heater element circuit by allowing current flow to ground. The ECM monitors the voltage signal received through the heater element circuit and determines the state of the circuit by comparing the voltage detected with the factory specifications.
Symptoms

Causes
Possible causes of OBD code P0042 Hyundai
– Heated Oxygen Sensor (H2OS) Bank 1 Sensor 3 circuit open shorted to ground – Heated Oxygen Sensor (H2OS) Bank 1 Sensor 3 circuit poor electrical connection – Faulty Heated Oxygen Sensor (H2OS) Bank 1 Sensor 3 circuit – Heated Oxygen Sensor (H2OS) Bank 1 Sensor 3 circuit fuse – Faulty Engine Control Module (ECM) The Error code is generally activated on detection of the following conditions: The P0042 Hyundai is set when the ECM detects an open or shorted to ground condition on the heated oxygen sensor heater circuit
Possible Solutions
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. HO2S Heater Control Circuit Bank 1 Sensor 3 is the generic definition for the P0042 Hyundai; however your vehicle’s manufacturer may have a different definition and information for the P0042 Hyundai code.

Note:
1. The list of automotive Makes at the right edge of the screen. The currently selected ODB-ii codes is for the Hyundai makes.
2. Look up the other OBD II Trouble Codes, please use the search box. Enter the 5 character trouble codes in the search box and submit the search.
3. Don’t assume a particular OBD-II code means the same for other auto manufacturers as there are many makes specific codes in use.
4. If your OBD-II trouble codes are for a different car, select that vehicle series before searching for the diagnostic codes because not all OBD2 codes used by one manufacture are used by the other makes.
