1. A control system for an engine, the control system comprising:
- a control module;
a resistor connected in series between the control module and a non-contact position sensor,wherein the control module selectively detects a fault of the non-contact position sensor based on a voltage drop across the resistor; and
a bypass module connected in parallel across the resistor, wherein;
the bypass module selectively bypasses the resistor,the bypass module bypasses the resistor during calibration of the non-contact position sensor; and
the bypass module is disabled after calibration of the non-contact position sensor.

Abstract
A control system for an engine includes a control module and a resistor. The resistor is connected in series between the control module and a non-contact position sensor. The control module selectively detects a fault of the non-contact position sensor based on a voltage drop across the resistor. A method for controlling an engine includes providing a resistor connected in series between a control module and a non-contact position sensor, and selectively detecting a fault of the non-contact position sensor based on a voltage drop across the resistor.
