Thread: Update on GTP, cant figure out problem

The yellow wire gives out voltage and hz frequency, to the PCM.

So another update, I get voltage when key is on. When the engine is on, there is no voltage

It all turned out to be this. My o2 sensor could not get a reading so it blame the maf sensor. Believe it or not that's what happened. Weird but a advanced electrical tech looked at my car and told me. Later on that day my computer told me my o2 sensor malfunctioned. I ordered a bosch sensor upstream and a extension harness. After this all this better be up and over with, dying to put this gen v on
