Chrysler Repair: 2004 sebring limp mode

Question
165k mile 2004 Sebring in Limp mode and CEL on, speedo shows 10-15 mph at stop, will usually start off normal after setting for a while, goes into limp about 10 minutes in to driving.

second car for me, like to keep it since it's paid and in relatively good condition, or at least keep it running to trade in.

read a few boards, change out speed sensors, etc... could use some specific help.

thanks very much in advance for your assistance.

Answer
Hi Nathan,
Try turning the ignition switch: "on-of-on-off-on and leave on" doing that in 5 seconds or less elapsed time. Then watch the odometer window to see the mileage reading be replaced by 4-digit number(s) preceded by a P. Let me know what you see and we'll go from there.
It could be the output speed sensor but check for codes before throwing parts at the problem.
Please read the PS below and respond to it.
Thanks,
Roland
