Answer 1

P0725 Malfunction of engine speed sensor

Is there any related engine code that are stored, ? In order to have this code condition the TCM (trandmission control moduel) recieves the ECM (engine control moduel) engine speed signal, This code is from the ECM to the TCM. If the ECM does not have a related Engine speed code or Crank position sensor code, the problem is in the TCM.
