What is OBD-II Code P0067 – Air Assisted Injector Control Circuit High

When it comes to modern cars, it’s no longer an option to ignore the on-board diagnostics (OBD) system. This system monitors and reports on faults in your vehicle, and it uses standardized codes to do so.

One of these codes that you may come across is OBD-II Code P0067 – Air Assisted Injector Control Circuit High. This code can be a little confusing, but it’s actually quite simple to understand once you break it down.

In this article, we’ll explore what OBD-II Code P0067 means, what’s causing it, and how to fix the issue. We’ll also provide some additional information on OBD-II codes and how to work with them.

What is OBD-II Code P0067?

OBD-II Code P0067 is displayed when there is an issue with the air assisted injector control circuit. This code is related to the fuel system in your vehicle, specifically the fuel injectors.

The air assisted control system is used to help the fuel injectors deliver fuel to the engine more efficiently. When there is an issue with this system, it can cause problems with your car’s fuel delivery, which can affect its performance and fuel economy.

What Causes OBD-II Code P0067?

There are several potential causes for OBD-II Code P0067, including:

1. Faulty air assisted injector relay or fuse: The air assisted injector control circuit relies on a relay or fuse to operate. If either of these components are damaged or faulty, it can cause this code to appear.

2. Damaged wiring or connectors: The wiring and connectors in your car can become damaged over time, which can cause issues with the air assisted injector control circuit. This can happen due to wear and tear, exposure to the elements, or other factors.

3. Failed air assisted injector control module: The air assisted injector control module is responsible for controlling the air assisted injector system. If this component fails, it can cause the code to appear.

How to Fix OBD-II Code P0067

If you receive OBD-II Code P0067, the first step you should take is to check the air assisted injector relay or fuse. If either of these components are faulty, you may be able to replace them yourself or have a mechanic do it for you.

If the problem isn’t with the relay or fuse, you’ll need to check the wiring and connectors. Look for any signs of damage or wear, and replace any damaged components as necessary.

If neither of these steps resolve the issue, it’s likely that the air assisted injector control module has failed. In this case, you’ll need to replace the module in order to resolve the problem.

Overall, the best course of action when you receive an OBD-II code is to consult with a mechanic. They will have the knowledge and expertise to diagnose and repair the issue.

Additional Information on OBD-II Codes

OBD-II codes are part of a standardized system that is used in modern cars. These codes are designed to make it easier for mechanics to diagnose faults in your vehicle, and they can be read using a OBD-II code reader.

There are hundreds of different OBD-II codes, each relating to a specific issue in your car. When you receive a code, it’s important to consult with a mechanic to identify the root cause of the problem.

Frequently Asked Questions

Q. Can I ignore an OBD-II code?
A. It’s never a good idea to ignore an OBD-II code. Even if your car appears to be running fine, there could be an underlying issue that needs to be addressed. Ignoring a code could lead to bigger problems down the road.

Q: Can I clear an OBD-II code myself?
A: You can clear an OBD-II code using a code reader or by disconnecting the battery. However, simply clearing the code won’t fix the underlying issue. It’s better to consult with a mechanic to identify and repair the problem.

Q: How do I prevent OBD-II codes from appearing?
A: Proper maintenance and regular inspections can help prevent OBD-II codes from appearing. It’s also a good idea to address any issues as soon as they arise, to prevent them from becoming bigger problems.

Q: What are some common OBD-II codes?
A: Some common OBD-II codes include P0171 (System Too Lean), P0300 (Random/Multiple Cylinder Misfire Detected), and P0420 (Catalyst Efficiency Below Threshold).

Q: How much does it cost to have an OBD-II code diagnosed?
A: The cost of diagnosing an OBD-II code can vary depending on the complexity of the issue and the hourly rate of your mechanic. In general, you can expect to pay anywhere from $50 to $200 for a diagnosis.
