• Installation is the reverse of removal.

Red Oil Pressure Warning Indicator Light (LED) Lighting Condition

(*): When the oil pressure switch turns on within ten seconds after the red oil pressure warning indicator light (LED) went off, the indicator light goes on immediately.
(**): When the oil pressure switch stays on for 60 seconds, the red oil pressure warning indicator light (LED) goes on.

Oil Pressure Warning System Inspection

First Step

• Turn the ignition switch on.

  If the red oil pressure warning indicator light (LED) [A] goes on, go to the second step.

  If the red oil pressure warning indicator light (LED) does not go on, go to the third step.

Second Step

• Check the oil pressure switch connections (see Switch Inspection).

  If the oil pressure switch connections are good, go to the fourth step.

Third Step

• Disconnect the oil pressure switch connector [A] (see Oil Pressure Switch Removal in the Engine Lubrication System chapter)
• Ground the oil pressure switch connector to the engine, using an auxiliary lead [B].
• Turn the ignition switch on.

  If the red oil pressure warning indicator light (LED) goes on, check the oil pressure switch connections (see Switch Inspection).

  If the red oil pressure warning indicator light (LED) does not go on, inspect or replace the following parts.

  Red Oil Pressure Warning Indicator Light (LED) (see Electronic Combination Meter Unit Inspection)
  Harness (see Wiring Inspection)

If all items are good condition, replace the oil pressure warning indicator light controller (see Oil Pressure Warning Indicator Light Controller Removal/Installation).

Fourth Step

• Disconnect the oil pressure switch connector [A] (see Oil Pressure Switch Removal in the Engine Lubrication System chapter)
• Ground the oil pressure switch connector to the engine, using an auxiliary lead [B].
• Turn the ignition switch on.
  • The red oil pressure warning indicator light (LED) should go on.
• Disconnect the auxiliary lead.

  If the red oil pressure warning indicator light (LED) goes off, go to the fifth step.

  If the red oil pressure warning indicator light (LED) does not go off, replace the oil pressure warning indicator light controller (see Oil Pressure Warning Indicator Light Controller Removal/Installation).

Fifth Step

• Disconnect the oil pressure switch connector [A] (see Oil Pressure Switch Removal in the Engine Lubrication System chapter)
• Turn the ignition switch on and wait for ten seconds.
  • The red oil pressure warning indicator light (LED) does not go on.
• Ground the oil pressure switch connector to the engine, using an auxiliary lead [B].
  • The red oil pressure warning indicator light (LED) should go on with a delay.
• Measure the delay time.

Lighting Delay Time
 Standard: 60 seconds

If the lighting delay time is out of the standard, replace the oil pressure warning indicator light controller (see Oil Pressure Warning Indicator Light Controller Removal/Installation).
