Why does the Check Engine light keep coming back on?
The fuel tank evaporative system vent solenoid could be the failure because they are prone to getting dirt and debris in the solenoid filter causing them to not vent the tank properly. The valve will operate electrically.
Why is my Shift Solenoid not working properly?
Diagnosis is key when it comes to transmission problems, as various issues can cause similar problems. Trouble with wiring or sensors could be at fault instead. A faulty shift solenoid should be replaced. In some cases, the solenoid is integrated into the valve body and isn’t serviceable.
Can a solenoid be replaced in a car?
In some cases, the solenoid is integrated into the valve body and isn’t serviceable. This means the entire valve body will need to be swapped out. Some high-end vehicles also have the TCM built into the valve body. Replacement of these units can be pricey.
How does a solenoid work in a transmission?
Inside the solenoid, there’s a plunger surrounded by a magnetic coil. When the TCM triggers this coil, the plunger moves, allowing pressurized hydraulic fluid to flow to certain parts of the transmission. This allows the transmission to shift into the desired gear. There are two or more shift solenoids inside your transmission.

What are the signs of a bad vent solenoid?
Common signs include the Check Engine Light coming on, pressure in the gas tank, and failing an emissions test. 1. Check Engine Light is on 2. Pressure in the gas tank 3. Failed emissions test
Is it safe to drive with check engine light on?
Sometimes, multiple sensors send signals, indicating clues that something bigger has gone awry. You can still drive with the light illuminated, assuming the car is running and driving fine, but you should get it checked out as soon as possible.
What to do if you have a bad Shift Solenoid?
If you notice any of the following symptoms of a faulty shift solenoid, get your car to a mechanic right away. Avoid any highway use and have it towed, if necessary. If you leave it unchecked, your transmission can get damaged, which will lead to a very costly repair bill.
