What causes the ISB engine code EGR valve?
What causes the ISB engine code EGR valve?
It’s an 8 pin connector with a 5 volt supply voltage, ground return and 6 other circuits working the EGR position and motor. What caused the code was a failed automatic calibration procedure that is actuated every time the ignition key is on or while the engine is running.
Why is the EGR valve open at the wrong time?
This EGR Valve fault code popped up and it caused a slight hesitation on acceleration which would make sense if the valve is open at the wrong time. The EGR funnels cooled exhaust coming from the EGR cooler into the intake system to cut down on emission levels.
What was the code for the 1896 EGR valve controller?
The code was 1896 EGR Valve Controller out of calibration. In the end we replaced the EGR valve after checking the harness and connector for poor continuity and proper battery voltage levels. It’s an 8 pin connector with a 5 volt supply voltage, ground return and 6 other circuits working the EGR position and motor.
What to do if your Cummins engine has an EGR valve?
Cummins recommends checking the aftertreatment system after the repair has been made. A snap acceleration test will test the diesel particulate filter. On our bus everything checked out fine and it ran like a dream. In the video the location of the EGR valve made it dead easy to get to.
