P0067 trouble code definition

Air Assisted Injector Control Circuit High

What the P0067 code means

The P0067 code means that the powertrain control module (PCM) is detecting a higher voltage from the air assisted injector system circuit than was specified by the manufacturer. A range of acceptable voltage for this system is programmed into the powertrain control module and once the voltage goes outside of this threshold, the Check Engine Light will be illuminated.

What causes the P0067 code?

One cause of the P0067 code could be that one of the wires in the air assisted injector circuit has a short to ground allowing excess voltage into the circuit. It is also possible that the portion of the powertrain control module that controls the air assisted injector system may have failed, which would require replacement of the powertrain control module.

What are the symptoms of the P0067 code?

Symptoms of the P0067 code could include damage to multiple parts of the air assisted injector system. If the voltage this system is receiving is beyond specification, the air assisted injector valve may be damaged, the wiring in the circuit for this system could burn up due to the excess voltage, the injectors could be damaged, or the powertrain control module could be damaged depending on where the source of the problem is located. The engine may not run differently immediately, however, once other system damage has occurred, the engine may stall during deceleration.

How does a mechanic diagnose the P0067 code?

A mechanic would start the diagnosis of this issue by first checking the wiring in the system for shorts to other circuits or any damage to the circuit that may exist. It may also be necessary to use a high quality scan tool to test the vehicle’s powertrain control module for faults related to the air assisted injector system. This would only be the first step in the diagnosis of this issue.

Since this issue could potentially damage other parts of the system due to the excess voltage, the air assisted injector valve and the injectors themselves would also need to be tested for proper functionality. Once the source of the problem is found as well as checked for all other faults, the repair process can begin to get the vehicle’s condition corrected and avoid further damage.

Common mistakes when diagnosing the P0067 code

A common mistake when diagnosing the P0067 code could be replacing the powertrain control module without properly testing it. This would be considered jumping the gun and could potentially be a waste of money as a powertrain control module is usually very costly. It is very important to test every part of a system that you are diagnosing to verify whether all parts are functional or faulty before replacing any parts.

How serious is the P0067 code?

The P0067 may not seem as such, but it is in fact very serious. Once this code has been set in the powertrain control module for an extended period of time, certain parts such as wiring, injectors, the air assisted injector valve, or the powertrain control module could be damaged due the the voltage of the system being above the specification set by the manufacturer. If your Check Engine Light comes on and this code is set in the system, it is advised to have an engine diagnostic performed as soon as possible in order to avoid damage to your injection system and unnecessary expenses.

What repairs can fix the P0067 code?

Repairs that can fix the P0067 code would include:

Additional comments regarding the P0067 code?

If your vehicle has this code set in the powertrain control module, have your engine inspected and diagnosed as soon as possible because this code can cause damage to multiple parts of your fuel system, and in extreme cases, may prevent your vehicle from running. It is also possible that this code can cause other codes to be set in the system depending on how long this code has been set.

Rigoberto came on time & quickly diagnosed the problem- rats chewed thru wiring near the battery. He wasn’t able to fix it himself bc of parts, but gave me recommendations on where to go & how to not have the dealership sell me services that are not needed.
