EGR B Control Position Exceeded Learning Limit

Check these first

• EGR valve B carboned up so its learned position drifts
• A sticking EGR B actuator that will not hold position
• A worn EGR B seat letting the valve travel too far
• A short or open in the EGR B position circuit
• The EGR B adaption never resetting after a repair

What to do next

1. Read EGR valve B commanded and actual position live data
2. Inspect EGR valve B for carbon or sticking
3. Test the EGR B position circuit for opens and shorts
4. Run the EGR B relearn or adaption procedure with a scan tool
5. Replace EGR valve B if it will not hold a learned position
6. Clear the code and retest
