Throttle Pedal Potentiometer Bank 2 Reading Help

[Verbalize8899]

As can be seen in the attached (bottom left section), with my foot fully down, track 1 is reading 89.15% throttle, track 2 is reading 44.57%. My understanding is that the pedal sensor has two sensors and that they should either be nearly matching or opposite (one goes up while one goes down), in this situation it seems like track 2 has a bad connection / is failing.

If anyone who is familiar with this could help would be much appreciated.

(engine is off, hence the 6.15% throttle body position)

The voltage of each potentiometer should increase together, one just starts at a higher voltage than the other.

What issue are you having?

When data logging with Torque I saw the throttle body sensor was only reaching ~89%. At first I just thought it could be fully open and the ECU has learnt the limit. But now I'm seeing the pedal only ever reads 89% when fully depressed I'm wondering if I'm losing out on 10% of the throttle at WOT. There isn't any symptoms but it's like been like this since I got the car so I don't have any baseline to compare to.

Hmm, you could try looking at the same data with another logging tool to see if it’s the same.

Failing that, maybe physically look at the throttle body whilst the pedal is pressed to see if it’s fully opened.
