FUEL FILLER CAP?

SAAB Other

My '99 saab 9-3 has about 60,000 miles, I keep getting this message to " tighten fuel filler cap" I tried to tighten the gas cap but that's not it, what is that and where is it located.

It is the gas cap. Do you smell any gas? If not the tank pressure sensor could be bad, if you smell gas, check the filler pipe for pinholes. Also try buying a new cap, the valve on the cap may be NG!
