Quizplus · Accepted Answer

Trouble codes are set by the vehicle's computer when a sensor signal is out of its normal range, and this typically relates to voltage. When a sensor's voltage output is too low or too high, it indicates a problem that needs to be diagnosed and repaired. Current and Ohm readings can also be important in diagnosing certain issues, but voltage is the primary signal that triggers trouble codes.
