>> Repair short to ground or short to power in harness or connectors.

4.

CHECK COMPONENTS 

Check the following.

• Throttle position sensor 1 (Refer to 

EC-214, "Component Inspection"

.)

• Engine oil pressure sensor (Refer to 

EC-243, "Component Inspection"

.)

• Camshaft position sensor (Refer to 

EC-230, "Component Inspection"

.)

• Exhaust valve timing control position sensor (Refer to 

EC-230, "Component Inspection"

.)

• Accelerator pedal position sensor 1 (Refer to 

EC-292, "Component Inspection"

.)

Is the inspection result normal?

YES

>> GO TO 5.

NO

>> Replace malfunctioning component.
