I got the same code 51 on 88pickup too. I ended up finding out that the IDL-E2 within the TPS wasn't working. I've still to find out what caused it to fail but I'll try to trace the wires back to the ECU & do a voltage check & post the results, if it helps.

Here's the resources I've been using for the TPS:
