Exhaust Butterfly Valve Actuator Sensor Output Voltage Inspection


Output Voltage Standard: DC 3.46 3.76 V at pulley
original position

If the reading is out of the standard, check the exhaust butterfly valve actuator sensor resistance (see Exhaust Butterfly Valve Actuator Sensor Resistance Inspection).

If the reading is within the standard, remove the ECU and check the wiring for continuity between main harness connectors.

Disconnect the ECU and sensor connectors

To adjust the damping force, turn the damping adjuster [A] until you feel a click. The standard adjuster setting is the 18th click from the 1st of the fully clockwise position. If the damping feels too soft or too stiff, adjust it in accordance with the following table. Damping Force Adj ...

Drive Chain Lubrication Condition Inspection
If a special lubricant is not available, a heavy oil such as SAE 90 is preferred to a lighter oil because it will stay on the chain longer and provide better lubrication. If the chain appears especially dirty, clean it before lubrication. NOTICE The O-rings between the side plates seal ...
