my 98 infinity Q45. The brake light and service engine soon stays. I've had the car serviced. Is it a sensor? How much does something like this cost? Replies to this message: epettus (Oct 21, 2009 7:39 am)

Replying to: aircalgal (Oct 20, 2009 10:16 pm) Had the same problem and found that the altenator was charging at 13.4 volts but needs to be atleast 13.7 volts to turn lights off. Have your charging voltage checked
