Welcome to the forum.
With a good scanner, what stored OBD2 codes are present?
This thread has some good information.

Hopefully a new harness will fix your issue.
There was TSB issued for all 2005 KJs.
The Factory filled up the rear diffs with incorrect oil that chewed up the sensor!
The fix was to take your 2005 KJ to a Dealer who would drain and clean out the rear diff, fill up with the correct oil and fit a new sensor.

So hopefully your rear diff has the correct fluid in it!

Saw one post from a KJ owner who got the same error...removed the diff sensor and found small fragments of metal on it!

Bill do you have the TSB# for that?

 

[Billwill]

I will try to find it.....pretty sure it was on this very forum when it was in the old format!

OK it is on this very forum:

Thanks Bill.
I wonder what oil they used in the rear diff?
I'll resarch it later today after work.
