Code U2630 Chevrolet Description
The U2630 code for Chevrolet indicates that the Reductant Control Module (RCM) has lost communication with the Reductant Tank Temperature Sensor 2. The reductant system is an essential part of the vehicle's emissions control system, specifically in vehicles equipped with a Selective Catalytic Reduction (SCR) system. The Reductant Tank Temperature Sensor 2 monitors the temperature of the diesel exhaust fluid (DEF) in the reductant tank, which is crucial for the proper operation of the SCR system. When communication between the RCM and the sensor is lost, it can lead to issues with the reductant system's functionality, potentially causing increased emissions and reduced fuel efficiency.
