Question

Answer
Look at each wheel to see if the 2 wire electrical connectors are plugged in  or disconnect them and make sure the connections are clean and tight and plug them back IN and see if the lights are still ON. If they are you will need to test both sensors at the wheels and make sure they are OK OR you can try clearing the codes from the computer and see if the lights go out.
