Throttle Valve Solenoid: Testing and Inspection
1. Disconnect the linear solenoid connector.
2. Measure the resistance between the No. 1 and the No. 2 terminals of the linear solenoid connector.
STANDARD: 4.0 - 9.0 Ohms
3. If the resistance is out of specification, replace the linear solenoid assembly.
4. Connect the No. 2 terminal of the linear solenoid connector to the battery positive terminal and connect the No. 1 terminal to the battery negative
terminal. A clicking sound should be heard.
5. If not, remove the linear solenoid assembly.
6. Check that the linear solenoid fluid passage for dust or dirt.
7. Connect the No. 2 terminal of the linear solenoid connector to the battery positive terminal and connect the No. 1 terminal to the battery negative
terminal. Check that the valve moves.
8. Disconnect one of the battery terminals and check that the valve releases.
NOTE: You can see the valve movement through the fluid passage in the mounting surface of the linear solenoid assembly.
9. If the valve binds, or moves sluggishly, or the linear solenoid does not operate, replace the linear solenoid assembly.
