my car just started throwing a SES light this morning... car runs fine... went to autozone to check it out.. and this is how it reads:
troubleshooting p1456
evap~ emission control sys~ leak detected
(gross leak/no flow)
troubleshooting p1456
fuel tank temperature sensor circuit
malfunction


what could this be caused by? checked my gas cap... no problem there.. and i've always tightened my gas cap after a fillup.... i dont have any performance mods... anyone know what this may have been caused by??

 

For the evap check that lil black charcoal box under your rear left side. Maybe oe of the hoses are loose off the box
