- 2007 Explorer Limited
Hello all,
I wanted to share this in hopes it might help some one down the road. I bought a 2007 Explorer Limited V8 2wd back in January and it only has 2400 miles one it. Sounds hokey but I have known the person that bought it from new and the condition as to why it had such low mileage.
So here we go...
Wife calls and says the check engine light just came on and after AZ scanned it came back saying multiple cylinder misfire with only 6,000 miles on it. I had the injectors cleaned when I got it so I figured they had just gotten fouled out from that, this model also had the dreaded plugs that broke off in the head when you had 100k miles on them so this was a good reason to change them - it's a breeze on this model 30-45mins later everything was buttoned up. I cranked the car and the CE light was still on so I shut it off and disconnected the battery and that's when "IT" started.
I hooked the battery back up and it came up with P2112 and P2104 - throttle body actuator stuck???? The TB on this thing is clean as a whistle so at that point my mind is blown>>>> I thought maybe it was a recalibration issue and it lost the logic from the prior setting, so I was searching on the TB recalibration procedure - I couldn't find one so I kept moving along thinking the battery reset was the root cause. It was also funny that after I went and rented a OBDII scanner the code would never clear, it always showed active.
I had manually opened and closed the butterfly on the throttle body and felt a click at the very bottom as if the TB was at idle. I didn't know if that was some detent setting or not??? I pulled off the TB actuator motor from the TB and has someone cycle the ignition key and the motor spun but was noisy.
I pulled the two Phillips head screws off the back of the actuator motor and the motor spun freely with the case off that held the magnets. After I looked at if I couldn't believe what I found.......
One of the magnets had come unglued from the housing and would hit as the windings of the motor spun forwards and backwards, I guess it took too much voltage to spin it which caused the computer to measure beyond it's allowable threshold and put the car into limp home mode, i.e. would not go above and idle. Just to test my theory, I Gorilla glued the magnet back on the housing, tensioned the TB spring and hooked all wires and hoses up and BAM, no codes and everything worked perfect.
I then went to the Zone to return the scanner tool, used 17 bucks of rewards points and added 45 dollars cash and had myself a new TB actuator motor complete with spring tensioning tool.
Some may say this was a pointless read but I would have sure loved to have had this info last night.
Thanks-
