1990 E-150 E4OD Question

Oh, I should mention that I think the Neutral Switch, or whatever that thing is called now, is bad because it leaves the backup lights burning. I recently had to take them out and haven't replaced the switch yet. If that's not what sets the backup lights, I'm interested in how to fix that too.

Thanks,

bingo!

both ABS and VSS use the sensor in the differential

change it and get on with life

there is an updated NSS, or MLPS Manual Lever Position Switch in Ford-ese

wiring connector needs to be changed, instructions come with new switch

hint: leave the old shell on the wires, just slide it up the wires, till you're sure you have it right

then crush the old shell with Channel-Locks and remove it

Do I have to get the MLPS from Ford, or can I get it aftermarket? I checked price at my favorite parts supplier and I know they can get it. I just need to know if the Ford unit is that much better.

Thanks for your replies!

CJB

get the Ford unit

So there's no VSS at the transmission?

CJB

nope

Thanks so much

Ok. After looking at the van today, there indeed is a VSS at the Speedometer Cable output at the Transmission, and another one on the differential.

Hmmm...

CJB

replace the one at the transmission, should fix the shift problem

Ok, I replaced the VSS at the transmission. Since the shift issue only occurred one day and went away on its own, I can't tell a difference. I 'm sure that took care of it though.

As I mentioned before, I also have a ABS light on that I'd hoped would go away if I replaced the VSS. When the front VSS didn't make a change in the light, I also replaced the one in the differential. Unfortunately, the light is still on...

Any suggestions about the VSS?

Thanks,

CJB

I think this should be a new thread.
