{" Oh, one more thing; Telling someone to just pull a damned fuse is bullshit. Giving them possiblities of whats wrong, or something else helpful would be better. YOu claim in your profile to be a Master Mechanic. In my opinion, your fuse suggestion isnt very masterful at all. Im not going to claim to be anything other than a mater debater, but you know as well as I do that there are checks and methods to elimiate causes of his MIL}
Ladies / Gentlemen Thank God that wissnx01 has been banned, but too bad that he is back at wissnx-01 now, if he banned again maybe he will use /01 or +01 after the wissnx, who knows what he is going to use. Guys you should browse and see other post that he left....dude just terrible. This forums is suppose for people who need help and people who willing to help, We don't need people like wissnx01 or 02 or 03 who knows what he is going to name himself.
I have ASE certified, and what ishop4less said is right, NOTHING WRONG TO PULL EFI FUSE TO CLEAR THE CODE, IF IT STILL HAVE PROBLEM ECU WILL RESPOND BACK THE CODE. That is absolutely correct.
P0171 most problems that I knew is MAF sensor dirty/faulty. A dirty MAF sensor can cause a check engine light. The cleaning procedure is simple and inexpensive. Those owners who have installed a re-usable air filter (such as the TRD unit) will likely need this service sooner than others, since a small amount of the oil used on these filters is sucked in the intake tube and tends to coat the MAF sensor.
For all models, the MAF sensor is located just after the air filter housing. A full size pair of pliers will be helpful in depressing the lock on the electrical connector, just remember it's plastic, only squeeze enough to disengage it. Due to the layout of the components on various models, a 90 degree screwdriver may be required to remove the screws holding the sensor in the intake tube. Once the sensor is out, use electronic cleaner to spray the dirt off of the fine thermistor wires inside the unit. If you are going to use the little plastic tube provided with the cleaner, do not stick it down inside the sensor. The wires are very delicate and this is a very expensive sensor to replace. Once clean, let it dry, re-install it, and re-attach the electrical connector so that it locks into place. No other computer or electrical considerations are necessary, either before or after the service.
