About the Cobalt
The Chevrolet Cobalt first made its debut in 2004 under General Motors. The compact model was later discontinued and succeeded by the Chevrolet Cruze in 2020.
Chevrolet only released two generations since its initial debut. The second and latest of these came in 2011. There was a one-year gap between these generations due to General Motors discontinuing the model for 2010.
It was also sold as the Pontiac G5 in the United States. This represented a rebadged version of the Cobalt. The Chevrolet Cruze is often considered to be the new and improved version of the Cobalt. It is also very similar to the Chevrolet Equinox.
One of the most common issues that the model suffered from is P0455, which indicates that there is a gross leak in the evaporative emissions control (EVAP) system.
This code is almost always caused by a loose or defective gas cap. However, it is also possible that the vehicle requires a smoke test to pinpoint the leak.
Another common problem is P0102. This code indicates that there is a low voltage signal from the mass airflow (MAF) sensor.
This code is typically caused by a faulty MAF sensor. However, it is also commonly caused by a faulty or dead battery. Owners may have to replace one or both of these parts. Checking the battery is a good first step.
Fault code P0010 is another code that owners have commonly reported. This code indicates that there is a fault with the intake camshaft position actuator circuit.
This can be caused by a faulty actuator or even camshaft position sensor. In some cases, neglecting to change engine oil frequently enough can cause the actuator to get stuck. Checking the oil should be one of the first steps for this issue.
