You still need to check the tube. Remove the glove box and you will find hard tube about 5/8" dia. that goes toward the center of the car. There will most likely be no connection between it and the sensor tube that is below the little square grill at the top center of the dash. Go to Home Depot and get some foam water pipe insulation tubing. Fit the tubing over these two tubes to connect them.

Have a great day,
