Why is my Jeep driving so strangely?


Asked by Aug 01, 2016 at 04:20 AM about the 2009 Jeep Wrangler Unlimited Sahara 4WD

Question type: Maintenance & Repair

It was driving normally up until about 15 mins of
driving today despite normal use. Then on the
highway, with no change in driving conditions, it felt
like the engine was working too hard. This was at
highway speed. I glanced down to see that the
RPMs were staying in the 4000-5000 range, double
what they normally are shifted to even when easing
off the gas a little to try and get it to shift up. I
parked and on my drive home it started to do this
again about 10 mins into driving. I could hear the
engine working harder than normal.

When coasting down hills, ie giving it no gas at all, it
remained at about 4000 RPM!

The check engine light came on and it showed the
code P0846 when I checked for codes. When I
searched that up it seems like it could be a number
of things.

From the description of the problem, what could
this most be and how can I fix it?
