Hey Guys, I've got my k swapped datsun running and idling, but running into fault code 77 APS(main)/APS(sub) tracking error. I'm running a tilton pedal box with a variohm sensor and I've check the wiring from pedal sensor to harness. Also checked continuity from throttle connector on the harness to the ecu to confirm everything is pinned correctly and it is. I really don't know where to go from here. I even bought a new variohm sensor hoping the first one was possibly defective, but nothing. Currently when I calibrate the aps there is movement in aps(main), but absolutely nothing in aps(sub). Also the movement I do see in aps(main) goes from 5% aps to 100% aps. It literally does not see anything between 5% & 100%. On the bright side at least I have a spare now. I'm stumped on this and its the only thing hold the car back from being able to hit the dyno. Any input would be greatly appreciated.
Best,
Angel
