Intermittent faults are often difficult to track down. It would be helpful to see if there is any Freeze Frame information stored when the electronic throttle control fault/s occur. That might help determine the cause of the accelerator/throttle pedal, TB faults. You can try checking the continuity of the wiring to the throttle body, accelerator pedal and ECU, using your Ohm meter but I am skeptical that testing will reveal any problems. I think the best way to approach this is to log the accelerator pedal sensor measuring blocks, (there are two sensors for the gas pedal position, and the sensors are inverse of the other, as one increases, the other decreases.) and see if there is freeze frame information associated with the DTCs occurring. Keep in mind that the specific DTCs are for
implausible sensor signal values received by the ECU, NOT intermittent signal faults, even though the actual fault conditions occur intermittently. In this context the term "Implausible" means the there is something wrong with the sensor signal as received by the ECU, the voltage is to high, or to low, or there is something else wrong with the signal that the ECU recognizes as being outside of the acceptable allowable signal range limits. It is possible also, that the tuned binary file has been edited with the wrong values written into the bin file, that when certain operating conditions exist, the ECU is expecting to see sensor signal values significantly different than the sensor values at that instant. Freeze frame data could help determine what the source of the errors is from.
