5 blinks

Have trane xe 80. Showing 5 blinks. Flame sensed gas valve off. Replaced sensing rod and limit switch. Problem still exists. It is intermittent problem. Could it be control board or something else?

Need the model number for the furnace. XE80 is just a model name that doesn’t give any information.
Test for mA with no flame. Is there a reading?
Limit switch isn’t related or causing the issue.
