P0249 OBD-II: Turbocharger/Supercharger Wastegate Solenoid "B" Low
P0249 Severity
Should you fix P0249 yourself?
Identifying an OBD code is just the start of a complete diagnostic routine. Most trouble codes are caused by a sensor reporting a value that is out of range. Just replacing a sensor may not fix underlying issues. Be sure to understand the code, the part or system in your car that the code refers to, and the risks of delaying professional repair.
Proper diagnosis will save you time and money on unnecessary repairs.
Urgent codes indicate immediate action is necessary. These are urgent and significant malfunctions that can cause severe damage to the vehicle or harm the driver and passengers.
What causes OBD-II fault code P0249?
The Wastegate solenoid allows unneeded boost generated by the turbo or supercharger to vent the system. The engine control module (PCM) controls the wastegate solenoid. If the PCM cannot control the solenoid, it will set code P0249.The PCM may also disable the turbo or supercharger to prevent further damage to the system.
