Just had a B5254T 2.4 Engine replaced in a 1999 S70 GLT. I drove the car home with my scanner hooked up (about 5 miles), with no problems. Even the new turbo charger worked. While copying the VIN number and the License Plate number down and the car just idling in my driveway, I received two codes,one being a Manufacture specific code; P1618 (Fault in Lead between AW 50-52 and Motronic 4.3...[MIL Requested]) and a P0705 (Transmission Range Sensor Circuit [PRNDL Input]). I'm sure since these codes were not on the old engine, which was blown, has something to do with wiring possibly not hooked up or pinched somewhere.

Has anybody got any idea as to where these sensors are located or where and what I should start looking for? Also, next to the Check Engine Light or MIL, there's a flashing orange arrow pointing up.(?) What the Hell is that? I have no owner's manual and the car was bought by my nephew this way...without an Owner's Manual or any kid of Haynes Manual or books like it. I need a little advice here.

Much Thanks in Advance,

maybe the transmission computer has loose wiring?
