Speed sensor location.

I have a 2003 Ranger 2.3 that has the speedometer not working. I am wanting to check/replace the speed sensor but I have no idea where it is. Can someone please help me with the location of the speed sensor. Thanks

For 2003 4x2 it will be on the rear drivers side of transmission toward the top.
It is called an OSS(output shaft speed) sensor

You need a T-30 socket(Torx) to remove it

If OSS sensor is out Odometer would also not be working and automatic trans may shift harder

OSS sensor should show about 500 OHMs when tested with ohm meter

Thanks RonD. The odometer works but not the speedometer.

Then it won't be an OSS sensor issue, they both use that signal.
And the "Check engine light"(CEL) will usually come on when speed sensors fail

So Speedometer itself is the issue.
Not sure on repair options for that, pulling out the dash cluster is not that hard to do, and then have a look at the back side of it for issues.

You can get the whole cluster at wrecking yards or off ebay for $100-$150.
It would just be plug and play, but check that all bulbs are good before bolting it back in place.

Odometer is an issue when swapping whole cluster so see if you can find one with similar miles

You added that the wipers and dome light also don't work.

These have the GEM module in common, also called the Body Computer, it controls interior electrics.
Fuse #26, 10amp, in the cab fuse box is first place to check, if you have checked it already then pull it out and replace it with another 10amp fuse just to be sure.

Also Fuses #11 and #20, 7.5amp
