That tube is the vent. It should be installed to a small vent hose on the battery but I do not think this is causing the warnings. Sounds like there could be an issue with the electronic throttle. Disconnect just the negative battery terminal for about an hour. In that time check the two connections to the throttle. If all are clean and secure we will need to scan the vehicle to see if there are any stored fault codes. Also do a visual of the intake and air/vacuum lines. Let me know.
It was supposed to be installed on a small plastc tee that gts inserted into the vent on the battery. You may also see a two wire black connector that gets secured to the plastic battery box so we need to make sure that is not damaged.
Ok the wires do not hook up to anything however if they are shorted or crashed we can simply disconnect the battery and cut out the damaged part. As long as those wires are not exposed and touching each other or the body it should reset. We may need to clear the fault codes with a scan tool.
