Volvo: v70 check engine light, fuel pressure, pressure sensor

Question
OK, it's a 2003 with 53,000 miles. engine stopped running  and check engine light came on after I started it up. no trouble starting up.  Light is on and goes off and after 100 miles or so goes on.  Volvo expert says code is for fuel  pressure sensor but when he checked the fuel pressure, it was fine 55PSI. Sensor fuel trim was fine -1.6%. The car has been back 3 times. He reset the light and now, 120 miles later, check engine light is on again.  What do I do?

Answer
Dianne,
If the code this time is the same that would seem to mean that the fuel pressure sensor is in fact at fault or the system that monitors it. What else to do? Get an appointment with the dealers service rep and see if Volvo is willing to further to investigate the problem.
