The reductant sensor module converts the analog data to a digital serial message to the ECM. Reductant level sensor 3 is located at less than half range of the DEF tank level. Reductant level sensor 1 is located at low reductant level. Reductant level sensor 3 is highest, reductant level sensor 2 is located between sensor 1 and 3. The level sensor has three sensing elements. The level/temperature sensor gets power from the underhood electrical center and grounds through a chassis ground circuit. The reductant tank has a level/temperature sensor inside that tells the ECM the reductant level and temperature. Models Affected by PIP4887AĮquipped with 6.6L Duramax Diesel Engine RPO codes LML or LGH What the Service Exhaust Fluid P203D P21AB or P21B0 means A voltage within this range indicates a short to voltage. The ECM receives a serial data message from the reductant sensor module that the emission reduction fluid tank level sensor 1, 2 or 3 voltage is greater than 4.74 V for greater than 3 s. A voltage within this range indicates an open circuit, or The ECM receives a serial data message from the reductant sensor module that the emission reduction fluid tank level sensor 1, 2 or 3 voltage is between 3.56-4.74 V for greater than 3 s.
P21B0 – Reductant Level Sensor 3 Circuit High Voltage. A voltage within this range indicates a short to ground. The ECM receives a serial data message from the reductant sensor module that the emission reduction fluid tank level sensor 1, 2 or 3 voltage is less than 0.17 V for greater than 3 s.
P21AF – Reductant Level Sensor 3 Circuit Low Voltage. P21AB – Reductant Level Sensor 2 Circuit High Voltage. P21AA – Reductant Level Sensor 2 Circuit Low Voltage. P203D – Reductant Level Sensor 1 Circuit High Voltage. P203C – Reductant Level Sensor 1 Circuit Low Voltage. P203B – Reductant Level Sensor Performance, The ECM receives a serial data message from the reductant sensor module that the reductant level sensor indications are not plausible
