P 1297 supercharger-throttle connection: what is the reason for the pressure drop?

The fault code P 1279 indicates the fault of the VTEC control system. P 1297 this error code may be caused by the charge air hose falling off. You can lift the vehicle, remove the engine guard, and check whether the hose connection of the supercharger is normal, falling off or damaged.

Extended data:

P 1279 common faults and inspection methods:

1. Whether the negative pressure at the air inlet of the supercharger is too large is generally caused by the serious blockage of the air filter. The air filter is seriously blocked, which leads to the decrease of air quality entering the engine, which leads to the decrease of boost pressure.

2. Check whether the connecting pipe from the supercharger outlet to the engine throttle leaks. If there is air leakage, it will directly lead to insufficient pressure and pressure drop.

3. Check the joint between the engine exhaust manifold and the turbine for air leakage. If there is air leakage, it means that the power of the turbine is insufficient.

4. Check whether the supercharger is faulty, such as scratching the shell and poor operation of the suspension bearing.
