P 1297 where is the air leakage?

P 1297 generally indicates that there is leakage between the turbocharger and the throttle valve, indicating that there is leakage at the turbocharger/throttle valve or hose connection. The turbocharger uses the inertia impact of the exhaust gas from the engine to push the turbine, and the turbine also pulls the coaxial vane car to pressurize the intake air, thus improving the power of the car. After troubleshooting the car, it is necessary to clear the fault code. When clearing the fault code, it must be cleared according to the fault code clearing method specified for the corresponding vehicle model. Otherwise, some models of control computers will lose their "experience memory". After simply removing the iron wire at the negative electrode of the battery, the engine operation data stored in RAM will be automatically deleted, and the performance will deteriorate after long-term maintenance, and the fault code may reappear after short-term operation. In addition, some useful functions may not work.
