4. Posted August 6 COI0 Keyword bullet _ a _ _ _ JELELI IL was called to a shop to perform a program update on a 2006 Ford E250 van with a 6 0L engine Figure 1 This is a task I am asked to do on a daily basis There are many shops that do not make the investment to purchase a programming interface or to subscribe to automotive manufacturer websites to download programming files This may be due to the fact that they may not get enough calls for reprogramming to justify the cost or they may not want to expose themselves to the liabilities involved in reprogramming There are many precautions that must be observed while programming a vehicle The most important one is having the proper battery charger such as the Fronius Power Supply Figure 2 This device will maintain a uniform voltage in the battery under the different load conditions caused by power consumption changes during reprogramming as when cooling fans or even headlights come on in the process If system voltage falls out of range the programming procedure could be aborted with a possible loss of a controller The other dangers are Figure 1 c b Ford Fe5U van with a 6 0L engine LILIA by John Anello Auto Tech on Wheels the loss of the Internet connection a scan tool running out of power or vehicle cabling disconnections Any of these malfunctions will result in the loss of a new control module that cannot be returned if it is c

8. rpm with only a 26 throttle opening It was a no brainer as to why the vehicle was running so rich that it was blowing black smoke This vehicle had a MAF sensor that was out of range Or was it One of the cool features of the Ford IDS scan tool is that it will tie into service manual information on a code By simply highlighting the code in the upper left hand corner and scrolling down the information window on the right side screen displays the details of what can set this code Figure 7 Ford says that if you encounter a code P061B you should inspect for an improperly sealed air box or air filter which can result in inaccurate measurement by the air flow sensor In addition Ford claims that if water or snow contacts the hot wire element of the MAF sensor it may cause a spike in air measurement August eUin 3 Speeding Bullet Figure 4 Inspecting the MAF sensor the missing air filter bullet jammed into the MAF inlet Figure 10 Removing the MAF housing to clear the passage 25 4Tg s 2489 50RPM 20 78 TP2 TP_B 29 41 Figure 11 Rechecking the data graph reads a normal 25 GPS 4 Master Technician Online and now the MAF sensor Figure Ie This air filter speeding bullet had an adhesive failure This is all good information so at this point I needed to dig into the filter housing to check the integrity of the sensor assembly and its connector feed circuits prior to throwing a new MAF s
