rxv throttle - brake wiper errors

[rockfordpi]

2013 RXV, was itermittent run, now no run.

Batteries 50.1v
Brake OHMS at 27.5

When press accelerator:
POT 1 Wiper goes from 325 to 1024
POT 1 scaled goes from 81 to 693
Mapped throttle goes from 0 to 100%
Throttle command stays at 0.

When brake pressed no input values change:
Brake command starts of at 100% and stays 100%
Mapped brake starts at and stays at 0%
POT 2 does not move on either


Turn switch off and back on then
When brake pressed:
Brake command starts of at 51% and goes to 100%
Mapped brake starts at and stays at 51%
POT 2 wiper is at 1024 an does not move
POT 2 scaled is at 259 and does not move

Clearly something funky going in with brake wiper, I am getting lots of brake wiper faults and I can replace that tomorrow. However, also getting some throttle wiper and position faults (not as many though).

I am wondering if I am missing something, is there something that could cause BOTH wipers to give errors?

Got it. Replaced the brake pedal position sensor and it seems to have resolved the issues.

Note to anyone who has this problem in the future, the brake pedal position sensor impacts (possibly inhibits) the throttle sensor.

The commonality is they both get their 5v source from the same supply inside the controller. If one sensor is screwing with the 5v circuit, the other sensor will be offline too.
