Scantool doesn't close the vent solenoid? 

 

 

 

 

 


genisysHave you ever had your scan tool NOT be able to close an EVAP vent solenoid?

 

 First of all, it’s NOT a fault of the scan tool. Some car companies don’t even have the ability to do this task!

We are going to use a voltmeter to handle this new way of closing the vent solenoid. (Can be applied to most models*)

 

 

1. Disconnect the plug-in on the EVAP vent solenoid.

2. Turn Ignition key ON with Engine NOT running.

3. Use a voltmeter to test which one is (pos) & (neg)

REMEMBER WHICH ONE IS WHICH!

6. Rotate the selector to the Amp position.
7. Move the “RED” lead to the Amp position.
 
Now the voltmeter is an amp meter and will be a direct current path to ground the vent solenoid.

9. With the Ignition key ON, engine NOT running, touch the black lead to the negative post of the vehicles battery.
When you touch the black lead to the battery (with key on) it will energize the solenoid -“Closing it”.
