Hello and thank you for choosing Just Answer.
The check engine light indicates that the car's computer has found a fault and stored it in the system. The fact that the P R D N are lit, indicates that the fact has to do with a transmission fault. You need to have an OBDII scan done on the car to find out what is triggering that light and what the car has stored.
You can get this scan done for free at any parts store. Simply ask for an OBDII scan and print out.
okay, the scan tells me output speed sensor. Can you tell me anything about the fix?
