c1223/4 are wheel speed sensors, but you have to know which one they are so a mechanic is going to have to check there is no code c0300. the 404 code is the EGR valve is sticking which cannot be repaired and EGR valve has to be replaced. 502 is vehicle speed circuit is low which may mean a speed sensor and 1189 is oil pressure problem which can be a short or low on oil.
