Alot of times, the code 52 is from the KS wiring, and not from the KS itself. Usually rewiring the 2 KS on a Turbo Supra (or 1 on a N/A) will correct the problem. Here is the step-by-step rewire page, and here is a thread in this forum discussing the rewire.

And make sure you have that negative battery cable disconnected or you pull the 15 amp EFI fuse out for a few minutes to erase the code from the computer.

Thanks for the response!

What goes wrong with the factory wiring that we need to rewire the KS?
