2003 Ford Escape DTC codes P0141 and P0161

MIl came on and after using scanner I got the codes dtc p0141 and p0161. I changed both sensors.

Light came back on. Checked again with scanner and got the same codes. I recently had someone change the alternator and it looked as if the wiring was messed up so I took to the shop and the mechanic taped the wires and turned off the codes. I drove 5 miles parked my car. When I got in it as soon as I turned the ignition on the mil came back on. I am taking back to the shop tomorrow, I want to be able to tell them what and where to look. I have to go back out to sea next week and want to leave the car in good condition for my daughter. As I will be gone on 6 month west pac
