Take a look at the lift sensor mounted on the left front fender.
You cannot repair an O2 sensor. Replace it.
Code 0715 is for an input shaft speed sensor circuit malfunction. Changing the speed sensor out for a new one should fix the issue.
you take it apart and fix it
Check the O2 sensor(oxygen sensor) AFTER the catalytic converter
You need to get a die that fits. Probably cheaper to buy the sensor
The heater in the oxygen sensor has failed. Its a good idea to replace BOTH oxygen sensors at the same time. If one has failed the other won't be lasting very long.
around 500 dollars at dealership
you take it to the people to fix it.
The only thing you can do to them is change them.
Replace it. Sensor 2 is the one AFTER the catalytic converter.
Unfortunately there is no fixing an O2 sensor. If the "check engine" light is on due to an O2 sensor, it can only be remedied by replacing the bad sensor.
