Abstract
Methods and apparatus are provided for detecting sensor wiring faults. A difference is determined between a high voltage and a low voltage. The high voltage and the low voltage are both related to a sensor that includes a high-voltage wire and a low-voltage wire. A determination is made whether the difference has dropped based on a low-voltage threshold. After determining that the difference has dropped, a fault in the high-voltage wire is indicated. A determination is made whether the difference has risen based on a high-voltage threshold, where the low-voltage threshold is less than the high-voltage threshold. After determining that the difference has risen, a fault in the low-voltage wire is indicated.
