Throttle miswire detection

An electronic throttle miswire detection system comprising:

• an electronic throttle including a throttle plate, a throttle actuator, a first throttle position sensor, and a second position sensor;
• and
• a powertrain control module (PCM) coupled to the throttle actuator, the first throttle position sensor, and the second throttle position sensor, the PCM adapted to control an angular position of the throttle plate, the throttle plate adapted to maintain a default position in which a default position value is measurable by the first throttle position sensor and the second throttle position sensor, and the throttle plate further adapted to maintain a closed position in which a closed position value is measurable by the first throttle position sensor and the second throttle position sensor, wherein the PCM is further adapted to compute a negative slope sensor difference consisting of the default position value as measured by the first throttle position sensor less the closed position value as measured by the first throttle position sensor, the PCM further adapted to compute a positive slope sensor difference consisting of the default position value as measured by the second throttle position sensor less the closed position value as measured by the second throttle position sensor;
• whereby, in response to a less than zero value for one of the positive slope sensor difference or the negative slope sensor difference, the PCM is adapted to deactivate the throttle actuator.
