the reason is weak pull up resistors on the SCL & SDA lines. Now, one I2C sensor is not accessible and has 1K pull ups on the board that I cannot get at to change.
I guess I'm expecting the pull up value needs to be closer to 4K7 rather than 1K
It would not make much of a difference having 1K as opposed to 4K7.
