Question

high voltage bank 1 sensor 2 what is wrong light go on after about 5 miles

Answer 1

HI there,

This code usually means that the heater circuit inside the sensor is reporting to much voltage back to the computer. If the voltage is to high for to long, especially after the ecm turns the heater off, then you will get this code. Usually replacing the sensor will resolve the issue.
