What does the P2008 code mean?

The P2008 code relates to the intake manifold runner control circuit. The intake manifold is responsible for directing the air and fuel mixture into the engine, and the runner control circuit is responsible for controlling the flow of air into the engine. When the engine control module (ECM) detects an issue with the runner control circuit, it will trigger the check engine light and display the P2008 code.

Drivers should take the P2008 code seriously, as it can lead to a range of issues with their vehicle’s performance. These issues can include reduced power, decreased fuel efficiency, and even engine damage in severe cases.

What causes the P2008 code?

There are several possible reasons behind this code and that’s what makes it difficult for drivers to figure out what’s behind it. We decided to give it a shot by taking you on a tour of the most common reasons that trigger this code:

Problems with the intake manifold runner control solenoid valve

The intake manifold runner control solenoid valve is an important component of the variable valve timing (VVT) system. It’s responsible for controlling the flow of oil to the actuator that controls the length of the intake manifold runners. If the solenoid valve fails or becomes damaged, it can cause a variety of issues with the VVT system which may cause the code P2008.

Damaged or faulty wiring in the runner control circuit

If there is an issue with the wiring in the runner control circuit, it can cause problems with the VVT system and trigger the P2008 code. There are several ways that damaged or faulty wiring can lead to this code, including short circuits, open circuits, or even corrosion and damage.

Blocked intake manifold

A blockage in the intake manifold can cause a restriction in the flow of air to the engine, which can lead to a variety of issues with engine performance. In some cases, this blockage can also trigger the P2008 code.

Which car models does the P2008 code affect the most?

The code P2008 can appear in any car with the intake manifold runner control circuit, but there are some vehicles that received a far greater number of driver complaints regarding this issue than others. We’ve done some digging and these are the models that are most likely to be plagued by the code:

• Mazda CX7: The Mazda CX-7 is known to have issues with the intake manifold runner control circuit which could trigger the code P2008.
• Volkswagen Jetta: Another model that is prone to issues with the VVT system and the P2008 code is the Volkswagen Jetta. This code can be caused by a malfunctioning intake manifold runner control solenoid valve.
• Lincoln MKZ: This model is more prone to the P2008 code due to issues with the intake manifold runner control solenoid valve.

How to diagnose the P2008 code

Diagnosing the P2008 code requires specialized tools and equipment, as well as a good understanding of automotive systems. Still, you can apply some methods even without professional help, so here’s a complete overview of the main ways of diagnosing this code:

Use an OBD2 scanner

The first step in diagnosing any check engine light is to use an OBD-II scanner to pull the diagnostic trouble codes (DTCs) stored in your car’s computer. This will tell you that the P2008 code is present, but it won’t tell you what’s causing it.

Testing the solenoid valve

The intake manifold runner control solenoid valve is a common culprit of the P2008 code. Testing this component can involve using a multimeter to check for proper resistance, as well as checking for proper vacuum and oil pressure.

Inspecting the intake manifold

The intake manifold is responsible for delivering air to the engine cylinders. Inspecting this component can involve checking for blockages, debris, or damage that could be affecting engine performance.

How to fix the P2008 code

The cost of fixing the P2008 code will depend on the specific issue and the make and model of the vehicle. Even so, some methods of fixing the code are pretty much the same regardless of the vehicle type you drive, so here’s what you can do:

Replacing the intake manifold runner control solenoid valve

If the solenoid valve is found to be faulty or damaged, it can be replaced with a new one. This involves removing the old solenoid valve, installing a new one, and testing the system for proper operation.

Repairing or replacing damaged wiring

If there is an issue with the wiring in the runner control circuit, it can be repaired or replaced as needed. This might involve soldering or crimping new connections, or replacing damaged wiring altogether.

Replacing the intake manifold

In some cases, the intake manifold may need to be replaced if it is found to be damaged or worn. This involves removing the old intake manifold and installing a new one.

Checking and repairing the vacuum lines

Vacuum lines are responsible for delivering vacuum pressure to the VVT system. Checking for leaks or blockages and repairing any damage can help restore the proper operation of the VVT system and eliminate the P2008 code.

How to prevent the P2008 code

If you wish to prevent the code P2008 from happening again once it’s fixed in your car, there are several things you can do. Most of these include just the regular maintenance tasks, while others could be more challenging, so here’s our list of preventive measures:

• Regularly replace the air filter
• Have the intake manifold checked during every other service
• Properly maintain the air intake system after clearing the code

Doing this should give you a break from the code P2008 in the long run and it’s also good for the combustion ratio to check up on the air intake system every once in a while.

Our take

Ultimately, it all comes down to taking matters into professional hands to deal with the code P2008, but that doesn’t mean you can’t do anything yourself. We hope to have demonstrated that during this guide on solving the code, so feel free to rely on tips from our experienced automotive experts to fix and clean the code.
