Chevrolet Corvette Fault Codes

About the Corvette

The iconic Corvette first made its debut back in 1953. In its 70-plus years on the market, there have been a total of eight generations of the 2-door sports car.

The model has been steeped in speed and racing heritage. This has led to a number of very high-performance variants created for racing over the years. These models were given the designation of CX-R, where the X stands for the generation.

There have also been a number of Z variants that are performance models for the road.

Competition for the Corvette has typically come from the likes of the Porsche 718, Toyota Supra, and BMW Z4.

When it comes to sports cars, fault codes can be serious problems. The most common of these is P0101, which indicates that there is an issue with the MAF sensor.

In most cases, this is the result of a faulty MAF sensor. However, it is also possible that the sensor itself has just become too dirty to function properly. Either way, checking the sensor should be the first step in fixing this code.

Another code that is less serious but just as common is P0449. This code indicates that the vent solenoid in the EVAP system is not working properly.

This is often caused by a defective solenoid. However, some owners have reported that the fuse for this valve can be blown. This is typically fuse #13.

Another common code is P0300, which is a very serious one given the powerful engines fitted in Corvettes. This code is logged when multiple random misfires have been detected.

With any luck, this can be fixed with new spark plugs and ignition coil packs. However, it can be a very painful process to find the cause of this dreaded code.
