2000 focus - check engine light
scanned the codes and came up with " P0720 " output speed sensor circuit malfunction. Can anyone tell me if this part can be purchased at a parts store or do I need to go to ford house. Where is would this part be located ? My problem is when going down the road the speedometer goes to zero, the volume on the radio goes down, and there is some loss of power, and sometimes does not idle when you come to a stop. Any help will be appreciated. thanks.
