Materials:
* Voltmeter or multimeter
* Wrench or ratchet
Steps:
1. Ensure safety: Park the vehicle on a level surface, apply the parking brake and install wheel chocks.
2. Locate the solenoids: Locate the location of the automatic transmission solenoids on your Honda Stream. They are usually located at the bottom of the gearbox.
3. Disconnect electrical connectors: Disconnect the electrical connectors from the solenoids.
4. Check the voltage on the solenoids:
* Set the voltmeter to the DC current scale.
*Connect the red lead of the voltmeter to the positive terminal of the battery.
*Connect the black voltmeter lead to the solenoid terminal where the positive wire of the wiring harness connects.
* Start the engine and check the voltage at the solenoid.
*Voltage should be around 12 volts.
5. Check the resistance of the solenoids:
* Set the multimeter to the resistance scale.
* Connect the red lead of the multimeter to one of the solenoid terminals.
*Connect the black lead of the multimeter to the other terminal of the solenoid.
* Read the resistance value on the multimeter display.
* The resistance must be within the range specified in the repair manual.
6. Check for short circuit and open circuit:
* Connect the red lead of the multimeter to one of the solenoid terminals.
* Touch the black lead of the multimeter to the transmission housing.
* The multimeter should not show any values. This means that the solenoid is not shorted to the body.
* Disconnect the solenoid contacts.
* Connect the red lead of the multimeter to one of the solenoid terminals.
*Connect the black lead of the multimeter to the other terminal of the solenoid.
* The multimeter should show the resistance shown above.
Conclusion:
If test results show deviations from specified ranges, this may indicate a faulty solenoid. The solenoid needs to be replaced. If the test results are within the specified ranges, the solenoid is operating correctly.
