Help!! PCM issues.. 2007 Ford F-150 5.4L
Hey everyone... Please help me out... Baffled with this.
2007 F-150 5.4 4x4
PCM failed to commuciate with scanner.. Threw 25 codes. Tested alternator- bad voltage regulator. Checked all fuses. None blown. Checked #41,42, and #110 tell me if there's another fuse location for PCM..
However truck still runs great. Drives fine slightly miss during cruising.. Not really noticeable.. Only when going up hill.
Truck starts up and drives fine.. Going on 4th alternator.. Don't understand why alternator keeps going out.. Within 2 years possibly PCM shortening out alternator?!
Thanks for input
