Volvo Troubleshooting Questions? Ask a Mechanic for Answers ASAP
Thx Jerry. Once the new fuel pressure sensor unit is installed is there any "calibration" or computer reboot/update that needs to be done? I do . not have the equipment for that. Can you send step by step directions for the fuel sensor like you did for releasing the fuel pressure or is it as simple as removing the plastic housing, disconnecting the wiring and removing the one torx screw?
It has been many months since you helped me replace the fuel pressure sensor on My 2007 Volvo C70. Unfortunately that fix was only temporary. I continue to get the check engine light with codes indicating a small fuel system pressure issue. I replaced the gas cap before we changed the pressure sensor but I kinda had to take the cap apart to put the leash that holds it on to the gas filling port. Do you think my continuing problem is related to the gas cap or do I have a very small leak someplace that is just illusive?
Thanks Jerry. I guess it might be worth another few dollars to try another gas cap. Perhaps I damaged the seal on the newer one when I took it apart to attach the leash.
