Reductant Pressure Sensor
WARNING: This page is about a different car, the 2013 Ford F-550 Super Duty, 2013 Ford F-450 Super Duty, 2013 Ford F-350 Super Duty, and 2013 Ford F-250 Super Duty. However, it is still accessible from the selected car via links, so may be relevant.
The reductant pressure sensor provides feedback to the PCM, which regulates system pressure by controlling pump speed using pulse width modulation (PWM). The reductant pressure sensor is integral to the reductant pump assembly. For additional information on the reductant pressure sensor, refer to Reductant Pump Assembly description in this article.
