OBD-II DTC P0247 – Turbocharger Wastegate Solenoid A High
DTC P0247 meaning
DTC P0247 refers to a diagnostic trouble code that indicates a problem with the turbocharger wastegate solenoid A. Specifically, it signifies that the solenoid is experiencing a high voltage condition. The wastegate solenoid controls the opening and closing of the wastegate, which regulates the boost pressure produced by the turbocharger. When the solenoid fails or malfunctions, it can lead to improper boost levels, affecting engine performance and efficiency.
DTC P0247 symptoms
Common symptoms associated with DTC P0247 may include:
- Reduced engine power or acceleration
- Increased turbo lag
- Check Engine Light (CEL) illuminated
- Unusual engine noises, such as whistling or hissing
- Poor fuel economy
DTC P0247 causes
Several factors can lead to the occurrence of DTC P0247, including:
- Faulty turbocharger wastegate solenoid A
- Wiring issues, such as short circuits or open circuits
- Corroded or damaged connectors
- Vacuum leaks in the wastegate control system
- Faulty engine control module (ECM)
DTC P0247 seriousness
The seriousness of DTC P0247 can vary depending on the specific vehicle and its operating conditions. However, it is generally considered a moderate to serious issue because:
- It can lead to reduced engine performance and efficiency.
- It may cause increased emissions due to improper fuel-air mixture.
- Prolonged driving with this code can result in further engine damage.
