

If there is any malfunction, inspect the coupler component.  



If the coupler component is normal, replace the control valve body. (See CONTROL VALVE 
BODY REMOVAL/INSTALLATION [AW6A-EL, AW6AX-EL].) 



If foreign materials are stuck to the VSS, disturbance by magnetic 
flux can cause sensor output to be abnormal and thereby negatively 
affect control. Make sure that foreign materials such as iron filings 
are not stuck to the VSS during installation.  

CAUTION:



Water or foreign material entering the connector can cause a poor 
connection or corrosion. Be sure not to allow water or foreign 
material on the connector when disconnecting.  



Do not damage the terminals.
