I have a 1999 v70xc and the car will not go over 4mph. Two codes came up P1550 and P0460. Can someone give me any idea what to do?

 

Hello, From a generic OBD website:
P0460= Fuel Level Sensor
P1550= Vehicle Speed Sensor Intermittent
Go to the search function of this and the other Volvo boards and merely enter these
codes one at a time. Frequently the thread includes exactly what people in your
situation did. I have no experience with these. Good luck, Kira
