Pressure Feedback Exhaust Sensor: Description and Operation

EXHAUST GAS RECIRCULATION SYSTEM.
This vehicle does not use an ERG Valve or Differential Pressure Sensor.
The use of the new variable camshaft timing optimize the combustion procedure by improving gas exchange in the cylinders. As a result of this the exhaust emissions regulations can be met without the use of a pulse air system or an Exhaust Gas Recirculation system.
