Leaks In Intake System

  1. Check all connections after hot wire sensor for tightness and leaks. Check sealing of hot wire air sensor (no pinched gaskets).
  2. Mount self-made tool to airflow sensor using two 4 x 45 mm screws. See Fig 1 . Build up 14 psi through the airflow sensor using a tire pump. If leaks are in the induction system there will be a rapid drop in pressure and the presence of air escaping.
