My 1999 Dodge Ram , 3.9L, Automatic. When Driving, Usually When In OD, My Engine Will Sputter For A Moment. It Might Happen Once Or A Dozen Times In A 35 Minute Ride. My Engine Code Is P0107(map/bara Circuit Low Voltage) Also, My Speedometer Will Not Show Any Speed Until I Reach About 55 Mph. Then It Will Read Normal. I Have An Abs And A Brake Light On All The Time. I Have Replaced The Speed Sensor, Made No Difference. The Speedometer Problem Has Been There For A While, The Sputtering Has Just Started. Any Help Would Be Appreciated.

Thanks,

Terry

I had the same problem with the speedometer, abs lite, brake lite and check engine lite. The problem is a 2nd speed sensor located back on the real axel.  I had it replaced and all went back to normal.  Yours might be just unpluged. Mine had gone bad. Good luck.

if you got the rear wheel antilock brake then its the sensor (top of rear differential)that's causing the malfunctions
