Checking component

Check for air leakage in the intake system. In particular check the hose between mass air flow (MAF) sensor and throttle body (TB) for leakage and damage according to Check for air leaks in the intake system .

Check that the hose between the manifold absolute pressure (MAP) sensor and manifold is airtight and is not trapped.

Remedy as necessary.
