2000 Toyota Camry 4 cyl 119000 miles

Initially I had error codes P0401 and P0441. After replacing the EGR valve and O2 sensors (front & back), the P0441 has gone (O2 sensor) and P0401 still exists. Please help us in understanding the issue and I'm not sure why this P0401 still comes on even after the resetting the code by disconnecting the battery cable.

Appreciate if anyone could answer and assist me to fix the issue.
