Remove it and make sure it's clean. Also use weed wacker trim line and carb cleaner to clean the tube fully. Also check the harness for chafes and check the plug.

Update after checking over the harness and replacing the EBP sensor still have the issue took it for a long drive with my buddy watching the tablet found the HPOP was fluctuating. Cleaned the IPR and replaced the Oil Pressure unit beside the IPR (leaking oil out of the connector) no change.
Does it sound like the HPOP seals bad? or the whole pump. This one does have the early 03 round pump
