P0503 and P1500 P0503 Vehicle Speed Sensor (VSS) A Intermittent/Erratic/High P1500 Vehicle Speed Sensor Intermittent I've asked this in another board, but of course I'm like black listed nobody will say a word, VERY aggravating. On the 1997 F150, there is a black or brown wire? Ok lets call it a dark wire, that comes from the harness and passes through the tail housing into the t-case. I'm unsure what that wire does, I'm curious if thats the root of my problem this time or if the plastic drive gear is actually slipping on the output shaft again. A previous owner did not remove the pin and wire from the connector, cut and spliced it instead. I'm wondering if that has failed finally.

Klitch, pardon if i ask a dumb question here.. is there a wheel sensor also? or does it come from the trans alone? reason for the question is i had a - ok dont laff - crysler (dont want to speeelll it right - it was a POS!) and i had gobs of problems with the trans not shifting correctly. Seems the wheel sensor (rt frnt) didnt jive with what the TCM or it's sensor saw and it gave simular errors that the dealershit (spelled that one right) couldnt figure out until i went to a different non-dealer mechanic. B/L was, the wheel sensor was not only bad but the mech said it was set at an incorrect air gap. Debris ?..? Anyhow the result between the two confused the TCM. They changed the wheel sensor and there was peace in the kingdom.

maybe start with seeing if that wire has power, while going through differant modes (key on/off, gear changes, 4WD engage/disengaged) you get the idea

I do believe, with a little doubt in myself, that the 97's used a speed sensor on the t-case and trans? Later models used the speed sensor in the rear diff?
