I put a used motor in and cleaned the engine area with gunk and hosed it down. I never pulled out the transmission. I did take all the harnesses out ...the car never had any codes before ...it's a 2006 Ford Fusion 4.3L. I cleared the code but the odometer will not register anything ..ill drive about a 1/4 mile and the check engine light comes on and the odometer starts working ..(p0720) do you think the speed sensor shorted out with the cleaning.

Vehicle: 2006 Ford Fusion 4.3L

It is possile the sensor shorted, but also check the harness and make sure it is plugged in completely.

Also make sure you didn't miss any grounds on the harness. A bad ground can cause this
