I recently swapped a 1jz into my 98 sc300 and it runs great except it wont go into overdrive. Im guessing it has to do with my gated shifter. Does anyone know how to get overdrive to work?

I have a CEL code 31, this is why i thought the MAP sensor was wired wrong. Could this code also mean vacuum leak, because thats what its acting like.

I thought one wire is 5v signal one was 12v and the other was ground. My green wire reads zero with engine off and 2.xx when at idle, is this right? I just thought map was wrong because it won't hold idle very well. And it's running Rich at idle.

Also since I have one with 0 volts can I just run 12v to it?

Which wire is 5v?

I just finished a soarer 1jz swap into my 98 sc300. The map sensor plug is missing. I think I plugged it in right but I am only getting 5v to the blue with red and 0 volts to the green with black. Can anyone tell me the order the wires plug in and also which wire is ground, 12v, and 5v? Thanks
