Throttle Position Sensor (G69) - Implausible Signal

[ricekikr]

Is there an easy fix? = Throttle Position Sensor (G69) - Implausible Signal

CAR: 97 A4 1.8tqm

I got this code ever since I replaced my battery (old one was completely dead). After clearing the code it just keeps coming back after a short drive.

The weird thing is, vagcom still shows the proper throttle angle even with the code.

I did several TBA already. Is it normal for it to show around 6% throttle angle right after TBA, then I step on the throttle (engine off) a couple of times and it'l drop to around 3-3.5% throttle angle?

Things done:
1. TBA
2. Check wiring (TPS sensor wire's fine, didn't check other wires of throttle)

Haven't done, but could be done, too lazy LOL:
1. Try another ECU
2. Clean throttle
