Ticking 2jz and p2138 code (throttle/pedal position sensor)

Was doing donuts in my is300 and right after noticed a ticking sound from my engine bay, noise seems to be top end and when I scanned codes all I got was throttle/pedal position sensor. If anyone has had anything like this and could give me a pointer or 2 on where to go from here it’d be much appreciated

does it happen only when the engine is hot like that? Mine ticks when it's hot, but the timing is slightly off
