What is the code that is causing your car to fail the test?
The reason for that concern is because the computer cannot finish testing. You may have a sensor that is bad but not bad enough to set a code stopping the computer from testing all the sensors.
The most common sensor I run into is the fuel tank pressure sensor is bad and not allowing the fuel leak check.
Does your state have a waiver?
Also make sure the tank is between 1/4 and 3/4 tanks full not full throttle or the test starts over. Also drive a steady speed on the freeway for 5 miles without stopping and drive 5 miles around 40mph at steady speed no stopping to pass the test.
