Car with unfixable TPS code

We found that the problem with our intermittent power loss was the TPS was installed incorrectly. The throttle lever was inserted on the wrong side of the TPS locator guides. Reinstalling the TPS solved the problem.

Nice to have a car that works again.

On mine, I replaced part of the harness to relieve tension and it did nothing at all to change the problem. I soldered all connections well.

However, someone at a local shop had the TPS wiring harness replaced when he did the timing belt and his problem went away. Might try the TPS positioning thing, but I think mine is correct.

I have found I get the flashing ATF triggered by the TPS most in low speed driving, when the car is cold, but there is some stumble even on the highway gliding down hills.

If you get a flashing ATF due to the TPS, the car is drivable in 2nd or 1st gear lately so if it happens at low speed, I drive it in 2nd until I can get to safe place to shift to neutral and restart.

Can you describe in greater detail? I think mine is right but I want to be sure. Any pictures possible?

I think I finally fixed mine. Buddy squared the heads (shaved them), head gaskets, timing belt, drive belts, seals, etc. Anyway, he works for a Sube shop (not the dealer).

But he said he had a customer that replaced the whole main engine harness (goes to TPS, coil packs and about 10 other things) and that had fixed his random flashing ATF code.

I got one through his shop which can buy from the Subaru dealer at substantial discount. Anyway, I have driven it all week and can't get the TPS code or flashing ATF no matter what I do to it. The list on the harness is $179 for the 2000 legacy and it is some work to install. He had the engine out of the car and the engine down to the head gaskets, so it was no big deal to do it then.

Finally, there seems to be some tension where the TPS plug is on the harness, they just come that way. But on mine, that wasn't where the short was. I don't know where it was, but it wasn't right there because changing the plug and splicing the replacement plug in with extra wire to relieve the tension had not worked on the old harness.

Yes, and still the first time he had seen a solution for this problem was a couple months ago. Now they have fixed three of them including mine. The worst thing is if the intake isn't coming off anyway, he said it is about two hours labor to install so it isn't a happy fix if a lot of these are going out on people. Kind of ridiculous that a main wiring harness seems to be a maintenance item on a 2000-2004 legacy.

It turns out that the TPS install was not my problem since the problem came back a few weeks later. I replaced the wiring harness with a used part and the problem has dissapeared. Looks like something in the the harness was impacting the signal from the TPS.
