why does my Genesis G70 get a P0131 code

• •Check engine light illuminated

1. 1Scan the vehicle using an OBD-II scanner to confirm the P0131 code and check for additional codes.
2. 2Inspect the wiring and connector of the upstream oxygen sensor for damage or corrosion.
3. 3Use a multimeter to measure the voltage output of the upstream oxygen sensor while the engine is running.
4. 4Check the oxygen sensor heater circuit for continuity and proper voltage.
5. 5Inspect the exhaust system for leaks that could affect oxygen sensor readings.
6. 6Verify that the engine is operating at the correct temperature by checking the coolant temperature sensor.
