    Camshaft Position Sensor/Electrical Problems

    2007 Ford Explorer - never ending Check Engine Light loop...

    Hi all, 2007 Ford Explorer Eddie Bauer - about 116,000 miles on it. Honestly, it has treated me great - and I have also treated it great in return. Always up on the scheduled maintenance, and I've probably done more things to it that are not "needed" (depending on who you talk to) than most -...
