Friends....I replaced the Vehicle Speed Sensor, hoping to get my speedo working again on my '01 Deville. Had no effect, other than leave me too tired to walk afterwards, not to mention bruised knuckles and a sore back. Now I am realizing that all along the OBD has been showing PO 102...low current from the Mass airflow sensor. Before I spend $150 bucks on this I am wondering whether any of you may have had the same problem. And, whether anyone know if the two...digital speedo out (along with cruise, and odometer) and the Mass sensor...could be related. Both happened at the same time. Thanks for any input.
