1999 Dodge Ram 1500

Question: How many miles must I drive to get a reading on a new speed sensor?

Question

Visitor, 5.2L V8, San Diego, CA, July 22, 2011, 19:13

I had a new transmission speed sensor installed because the "engine light" was on and the reading indicated "P0720 output speed sensor malfunction". But now, I can't get smog certified because the technician says the reading is "incomplete" meaning I haven't driven enough miles for the new sensor to make a reading.

    The shop who installed the speed sensor should have preformed (at a cost) a monitor reset procedure. This is done to verify the repair is successful and to verify that there are no other underlying problems which would prevent the computer from completing its drive cycles. I would recommend to have them do this proceedure for you so you can get the vehicle smog tested.
