- If low oil pressure indicator is also on with engine running, check for possible mechanical failure. If low oil pressure indicator is not on, go to next step.
- Disconnect oil pressure sending unit. Turn ignition switch to ON position. Connect a fused jumper wire between ground and oil pressure sending unit (Yellow/Green wire). See WIRING DIAGRAMS . If oil pressure gauge reading varies, replace oil pressure sending unit. If oil pressure gauge readings do not vary, go to next step.
- Disconnect instrument panel connector I-10. Connect a fused jumper wire between ground and instrument panel connector I-10 cavity terminal No. 19. See Figure . If oil pressure gauge reading varies, go to next step. If oil pressure gauge readings do not vary, replace instrument cluster. See INSTRUMENT CLUSTER under REMOVAL & INSTALLATION.
- Repair open in sending unit circuit (Yellow/Green wire at sending unit; Yellow/Black wire at instrument panel). See WIRING DIAGRAMS . Recheck system operation.
