Starter motor.
To test a solenoid vent valve circuit, first ensure the power is off and disconnect the valve from the circuit. Use a multimeter to check the resistance across the solenoid terminals; a reading within the manufacturer's specified range indicates the solenoid is functional. Next, reattach the valve and apply power to the circuit while monitoring for proper operation, ensuring the valve opens and closes as expected. If the valve fails to operate, further diagnose the circuit for issues like faulty wiring or a malfunctioning control module.
In the starter circuit, in many automatic transmissions, in EVAP circuits,
When a vent valve solenoid control circuit shows constant volts on both wires when connected, it could indicate a short circuit or a malfunction in the solenoid itself, causing both wires to read the same voltage. Additionally, if the solenoid is stuck in a closed position or if there's a wiring issue, it might not allow for a proper voltage differential, leading to identical voltage readings. It's also possible that the control module is providing a constant voltage signal, rather than a pulsed or switched signal, which is typical for solenoid operation. Checking the circuit for continuity and inspecting the solenoid for faults would help diagnose the issue.
Usually the problem with this code is an open vent solenoid valve. 12 volts is provided to solenoid and the pcm grounds the solenoid. When the pcm checks the circuit it is looking for 12 volts on the wire at pcm. The pink wire should have 12 volts and the white wire should be the ground circuit from the pcm. Ohm your vent valve it will probably be open.

jump out the solenoid or relay. This will close the circuit for the high current.
If you're experiencing a transmission reverse gear lockout solenoid circuit problem on your Jeep Rubicon, start by checking the fuse associated with the solenoid circuit for any signs of damage or failure. Inspect the wiring and connectors for any corrosion or loose connections that could disrupt the electrical flow. If those components are in good condition, use a multimeter to test the solenoid itself for proper operation. If the solenoid is faulty, it will need to be replaced to restore proper function.
