1999 Jeep Grand Cherokee V8 5.9L 101,500 miles. Check engine light recently came on. 2 different OBD units said it was due to Output Speed Sensor (code P0720.) Although I felt a very slight delay or skip when the check engine light came on, the car is driving nromally. Is this problem critical or can I get away without fixing it? If I should fix it can I wait until I take the car in for 105k service or should I get it fixed right away?
Thanks for your help,
