002431
What This Code Means
Continuity measured on Wire 86 when infinite resistance is expected; Low oil pressure switch indicates INFINITY when engine is shut down and DMM connected to terminals; Low oil pressure switch indicates CONTINUITY when AUTO-OFF-MANUAL switch is set to MANUAL and engine has had a chance to build pressure, with DMM connected to terminals; 3.3 VDC is not measured at Wire 86 when DMM is connected to Wire 86 and a good ground, with engine shut down and Wire 86 disconnected at the LOP switch; CONTINUITY is not measured between disconnected Wire 86 and Wire 86 when DMM is connected with harness connector disconnected from controller and Wire 86 and Wire 0 disconnected from LOP switch; CONTINUITY is measured between disconnected Wire 86 and an engine ground when DMM is connected with Wire 86 still disconnected from LOP switch and controller harness connector
Possible Causes
- •Short to ground on Wire 86
- •Faulty LOP switch
- •Low oil pressure (implied by expected behavior)
- •Continuity issue on Wire 86 from the LOP switch back to the J4 connector
- •Faulty Wire 86 between the LOP switch and the controller harness connector
Suggested Actions
- 1Repair or replace as needed (referring to the shorted component or wiring)
- 2Replace the LOP switch
- 3Check continuity on Wire 86 from the LOP switch back to the J4 connector
- 4Repair or replace Wire 86 between the LOP switch and the controller harness connector
- 5Repair or replace as needed for short to ground on Wire 86
