EGR COOLER BYPASS VALVE POSITION SENSOR [SKYACTIV-D 2.2]

id0140z7257400

Purpose/Function

• Detects the EGR cooler bypass valve open/closed condition as basic information for mainly EGR control and boost control.

• Detects the EGR cooler bypass valve opening/closing condition and sends it to the PCM as the EGR cooler bypass valve opening angle signal.

Construction

• Built into the EGR cooler bypass valve.

• A Hall element has been adopted as the detecting element for detecting the EGR cooler bypass valve opening/closing condition.

Operation

• Sends the signal, which fluctuates according to the EGR cooler bypass valve opening/closing, to the PCM.
