Buick Regal Fault Codes

About the Regal

The Regal first made its debut as a sub-brand of the Buick Century in 1973. It was later converted to the Regal nameplate just three years later.

During its time on the market, a total of six generations hit the North American and Chinese markets. However, the North American variant was discontinued in 2020. Upon its discontinuation, Buick’s lineup became entirely made up of SUV offerings.

During its later years, the Regal went up against the Acura LTX, Ford Fusion, and Nissan Maxima, to name a few competitors.

Unfortunately for owners, the most common issues for the model are fairly serious ones. In fact, the top three fault codes are all related to the camshafts and their components.

Fault code P0014 is the most commonly reported of these. This code indicates that the exhaust camshaft is over-advanced and the onboard computer cannot fix it by itself.

This code can be caused by a number of things besides an actual timing issue. Some relatively simple fixes can be replacing the exhaust camshaft position sensor or replacing the engine oil with the correct type.

However, the next most common code can also help pinpoint the issue. Fault code P0013 indicates that the exhaust camshaft actuator solenoid is malfunctioning.

If both of these codes are logged together, replacing the solenoid can be the fix for both. This issue is actually covered by a special warranty for 2014 models fitted with the 2.0L turbocharged engine because it is a known issue for that engine.

Over to the intake camshaft, fault code P0010 is also a commonly reported problem. This code is the same as the previous one but for the intake camshaft.

Again, it is important to check both the intake camshaft solenoid and its circuit for any issues.
