Error codes

[dphatch]

Check engine light came on this morning while out for coffee. Codes tht came up where 461, which is for Fuel level sensor and 455 which is for the fuel tank indicating a major leak. No issues noted with the car and cetainly no major fuel leak. Planning to erase the codes and see if they come back but thought I might check in here first. Car has never thrown any codes since new so these two seem a little strange as the first ones.

Check the fuel cap and o-ring on it for sealing.

did that and the O ring looks like new. i got a strong gasoline odor though when i removed the cap which i don't recall ever getting before. last time I refueled it took a while for the fuel level indicator to get to the full level from the 3/4 mark. not sure if either are related

You bet. The first thing I saw in a 993 TT when the fuel level sender went south was the fuel guage sticking on refuels.

The slow fuel level reading has so far not happened again. I erased the codes and they have not retruned but will pay more attention to he fuel gauge when refilling. Is the sending unit RR a DIYI project ? Edited June 7, 2013 by dphatch

Not in the 993 TT. After the unit was replaced it had to be calibrated by adding an exact amount of fuel to an empty tank. Although I guess you could do it yourself, I think I'd rather let the tech blow himself up. :eek:
