Technician A says the back pressure transducer may be incorporated into the design of the EGR valve. Technician B says negative back pressure transducers use the vacuum in the exhaust between pressure pulses to modulate the EGR flow. Who is correct?

Question

Quizplus · Accepted Answer

Both Technician A and Technician B are correct. The back pressure transducer can indeed be part of the EGR valve's design, allowing for more precise control of exhaust gas recirculation based on the pressure in the exhaust system. Technician B's statement about negative back pressure transducers using the vacuum in the exhaust between pressure pulses to modulate EGR flow is also accurate. This method helps in optimizing the EGR flow for better engine performance and reduced emissions.
