Oil Pressure Switch Test

  1. Locate oil pressure switch at top of oil filter housing and disconnect connector. Using DVOM, with engine off, ensure continuity exists between switch terminal and switch ground. If continuity does not exist, replace switch.
  2. With engine running at idle, continuity should not exist. If continuity exists with engine running, turn engine off immediately. Use manual oil pressure gauge tester to ensure oil pressure is greater than 5-10 psi at idle. If oil pressure is as specified, replace oil pressure switch.
