Code P0871 on 2001 dodge durango
I towed a car less than a mile and had it in scond gear and and towed the car and had no problems. Went fine and drove 20+ miles home and still no problems then went to get up and go to work and srtarted the car and check engine light is on. Went to auto zone and I have a code P0871 and thats the only code there.
What do I do and do I really need to bring it to a dealer to fix it?
HELP!!!!!!
