| Description of the problem | Check engine light is on. Hecu internal failure. Active dtc present: c1237 primary pressure sensor signal. Sensor failure inside the abs control cycle. Values at pressure sensor changed from 0. 3 bar to 78. 0 bar; no change in supply voltage. Supply voltage constantly at 14v. Hyundai has mentioned that there are no active recalls and that this part is life threatening if it fails - but since the warranty has expired they are shying away. Online there are several known issues with hyndai and hecu. Specially for models before 2009. Its hard to believe that hyundai is not aware of this problem and seems like they are avoiding their responsibility and playing with human life. Would appreciate if the government can do something. |
