Why Does the Urea Fault Light Illuminate in China V Trucks?
1 Answers
In the market, a large number of China V vehicles experience the illumination of the emission light after switching urea brands, leading to engine torque limitation that is difficult to resolve promptly. There are two main reasons for this issue: 1. The quality of the added urea is substandard; 2. The OBD system data correction process by the original equipment manufacturer takes a long time. Additional information: 1. The urea indicator on the car dashboard signifies that the dedicated urea reductant level is too low, preventing the engine from restarting or indicating an ADBLUE system fault. 2. Most dashboard displays rely on sensors; these sensing devices alter their resistance values based on changes in the monitored object's state, which are then displayed on the dashboard. The most prominent feature on the dashboard is the speedometer, which shows the vehicle's speed in km/h (kilometers per hour). The speedometer actually consists of two gauges: one for speed and another for mileage.
