I've got the codes: C1241, C1223, C0205, C0200 and U0126, U0124, U0123.

Question

If I replace both wheel sensors, will all of the above the codes go away?

Answer 1

C1241 Low battery positive voltage

C1223 ABS control system malfunction

C0205 Left front wheel speed sensor circuit

C0200 Right front speed sensor

U0126 ECU communication stop mode

U0124 ECU communication stop mode

When there is a C1241 that has to be done first, a low power will set all type of code with the ABS system. For C1241 you would need to check the charging system and have it resolved first then clear the code and retest for any code that may set.
