Oil pressure issuers on Toyota Tundra?

Very common problem,noticed on many Toyota tundras.

These Tundras had major issues with the oil pressure sending units. There was a technical service bulletin back in the day but only covered up through 2002 on the tundra and up through 2004 on the Sequoia.I would definitely have a physical oil pressure gauge installed to ensure that the oil pressure is fine. Make sure that you have oil change receipts from the previous owner for proper maintenance.
In most of cases new oil sending unit solves the issue.
This details will help.
Thanks.
