I have the same issue, my light comes on and off depending on how full my tank is. almost @ "E" it comes on, then when I fill the tank it turns off after a couple of days. Had MAF cleaned and checked, O2, fuel filter, new plugs, ect. Any ideas?

check your fuel pressure. misdiags are being down. saying maf sensor is issue. its not. take ur maf sensor off the air filter box/air filter box tube. get volt meter....test the sensor by blowing air into it. if u have a can of computer aerosol dust cleaner thats the best to use. lightly blow into the sensor.....then do a quick full shot of air.....if u notice the sensor fluctuating on the measurements.....sensor is good. then check your fuel pressure.......it has to be right on the money as far the specs for fuel pressure. TOYTECH24, How do you check the fuel pressure. I'm having the same issue, but what is strange is that my check engine light comes on when the tank is almost "E", then I will fill it and with in a couple of days it will go off by itself, it's a vicious circle.
