Cadillac Escalade Fault Codes

About the Escalade

The iconic Escalade model first made its debut in 1998 as a full-size luxury SUV. Since then, there has been a total of five generations to hit the markets. The latest of these was released in 2021.

The model represents the very first SUV to be sold under the General Motors brand and remains one of its best-selling vehicles to this day.

Because the model boasts a number of luxury features, it goes up against some high-quality competitors. The BMW X7, Mercedes-Benz GLS-Class, and Land Rover Range Rover are certainly among the most notable of these.

During its long time on the market, a number of common issues have been reported. The most common of these is P0420, which indicates that the catalytic converter in the first bank of the exhaust is not performing properly.

Owners have found that older models typically need to have their catalytic converters replaced if they have not been done in accordance with scheduled maintenance. In the case of a new converter, replacing the oxygen sensors can also be helpful for this issue.

Another issue that the model has faced often is P0171, which can be both fairly serious and hard to fix.

This code indicates that the engine is running lean. This can be the result of a wide number of things, but owners have noted that cleaning the MAF sensor and checking the fuel pressure are some of the best initial steps in fixing the issue.

Fault code P0011 is another common issue for the Escalade. This code indicates that the intake camshaft is over-advanced.

Owners have reported that a faulty camshaft position sensor can be the cause but there can be much more serious issues at hand. One of the more common ones is a defective camshaft actuator.
