How to solve the urea fault light on J6P?

This is caused by weak high-voltage spark or misfire, just check the ignition system. If the engine stalls easily when increasing speed, and sometimes there is backfire in the intake pipe or exhaust pipe popping, it is likely due to weak high-voltage spark, acceleration misfire, or ignition disorder. Notes: 1. Different types of engines have corresponding special maintenance tools. Be sure to confirm the specifications of the special tools and operate according to the correct procedures to avoid damaging the components. 2. For parts that are paired or have special requirements for assembly position, check the pairing marks when disassembling. If there are no marks, make assembly marks to ensure proper reassembly. 3. Pay attention to the disassembly of vacuum pipes. Do not pull the middle part of the hose when disassembling. When removing hoses with vacuum valves in the middle, mark the connection ends of the hoses to avoid incorrect installation. 4. Maintain the engine regularly, service the engine on time and by mileage, and choose the appropriate engine oil. Keep the coolant clean to ensure good heat dissipation of the engine. Regularly clean the oil and air passages of the engine. Ensure the engine has unobstructed oil and air intake channels.
