P2440 Chevy Equinox: Everything You Need to Know

The Chevy Equinox is one of the small SUVs in the market, competing with well-known brands such as the Toyota RAV4 and Honda CR-V. Like other vehicles, this car is bound to face various technical problems. Did you know that the P2440 code is one of the common issues the vehicle can face? The following is everything you need to know about this car.

What Is the P2440 Chevy Equinox Code?

According to EngineCodes, the P2440 Chevy Equinox occurs when the secondary air injection system has an issue. The system helps in reducing the carbon emitted through exhaust gases. The secondary air injection system contains various components which facilitate its smooth running. Such components include vales, a vacuum hose, and an air pump. If either of these elements malfunction, the vehicle’s computer creates the P2440 code. The code means that one should have the secondary air injection system checked as soon as possible before it can cause further damage to your car.

Symptoms of P2440 Chevy Equinox Code

The symptoms of this code vary depending on its cause. However, a check engine signal is the first symptom common to all causes. The signal could also be caused by other issues affecting the engine’s performance. Therefore, paying attention to the specific issues causing the P2440 code is the best approach. The best strategy is to use the car code reader to retrieve all the stored errors.

Alternatively, a weak acceleration, engine stalling, or low idle indicate a faulty air pump or valve. In such a case, you should have a mechanic inspect the secondary air injection system to determine the exact cause of the P2440.

Causes of P2440 Chevy Equinox Code

A faulty secondary air injection system valve is the main cause of the P2440 P2440 Chevy Equinox code. The faulty valve could be due to poor electrical connection or a shorted or open valve. The valve is computer controlled and determines the amount of air injected into the vehicle’s exhaust system. If the valve malfunctions, it would not allow air injection as expected, and this could cause engine failure. As soon as the failure occurs, the computer logs a P2440 code.

A faulty vacuum hose could also cause the P2440 P2440 Chevy Equinox code. In this case, the vacuum hose could be disconnected or clogged. When this happens, air does not flow as expected, which could cause changes in the air-fuel ratio. The occurrence causes an engine malfunction, and the computer would log the P2440 Chevy equinox code.

The air pump is a crucial part of the secondary air injection system. Its malfunction affects the functioning of the entire system because it disrupts air injection into the engine. If the problem persists, the engine will make it difficult to accelerate the car. The faulty air pump would also cause stalling during a cold start. It would also affect the exhaust emissions. In turn, the check engine light would switch on, indicating an issue with the secondary air injection system.

How to Fix the P2440 Chevy Equinox Code

The initial step in fixing a P2440 code is through inspection to determine which of the above issues caused it. Once the issue has been determined, the necessary repair takes place to ensure the car is in good condition. If a faulty valve is responsible for the cause, the mechanic will make the correct electrical connections or other changes. This would ensure the switching on and off process doesn’t interrupt the secondary air injection system functioning.

A visual inspection of the vacuum hose would determine whether it is disconnected or clogged. Disconnection is the common vacuum hose problem causing a P2440 code. In this case, a simple connection would correct the issue. Clogging occurs when an individual has used the car for a long time without regular servicing. When this happens, the mechanic fixes the issue by cleaning the hose. A replacement is only necessary when the vacuum hose is too worn out to sustain its functions.

Diagnosing the air pump focuses on the engine’s functioning. If the engine had acceleration issues, this pump could have issues. A faulty air pump can be fixed by replacement, costing approximately $300. Once the air pump is fixed, air is injected into the engine as expected, thus facilitating smooth running. The air pump ensures sufficient pressure in the exhaust. Such pressure is needed for the smooth running of an engine.

Mechanics also look for bent, broken, corroded, or pushed-out connector pins and make the necessary repairs. Ignoring such minor repairs could result in more car problems in the future.

Cost to Fix P2440 Code

When your car displays the P2440 code, the first thing that comes to mind is taking it to a mechanic and the amount it would cost you. The cost of such repair is hard to determine because various issues cause it. Sometimes, you might need to replace the car parts or make simple repairs. Therefore, your auto repair expert will diagnose the specific problem and give you a quote. Many mechanics would charge you up to $450 depending on the required repairs. The task could take up to an hour.
