david :

Hi thank you for your question hope this helps.

Have you checked the oil pressure with a manual pressure gauge?

In most cases this problem is do to the oil pressure sensor going bad.


Testing



  1. Disconnect the sending unit electrical harness.


  2. Using an ohmmeter, check continuity between the sending unit terminals.


  3. With the engine stopped, continuity should exist.



    NOTE

    The switch inside the oil pressure sending unit closes at 6 psi or less of pressure.




  4. With the engine running, continuity should not exist.


  5. If continuity does not exist as stated, the sending unit is faulty.
