What is P0067 fault code and what does it mean? What is the description for the Air Assisted Injector Control Circuit high fault? How can you fix the fault code P0067 What are the causes and symptoms of P0067 fault code
What is the P0067 fault code? What does it stand for?
This error code is triggered by the powertrain control module, (PCM), when it detects an improper or high signal coming from the air assisted injector or control circuit.
An internal combustion engine’s efficiency is directly affected by fuel atomization. A few vehicles use an air assisted injector system to send a precise amount of air into the injectors. Under certain driving conditions, a solenoid injects fuel into these injectors to increase fuel combustion and boost fuel atomization. This special injector is typically used to start cold engines. The engine will start more easily when it has cooled down. This is because it requires a richer fuel/air mixture to get started. Spraying the fuel evenly is possible by the atomization, which occurs when air goes to the injector.
The PCM will store the code P0067 if it detects a voltage signal from the air-assisted injection control circuit that exceeds the preset parameters. The PCM has preprogrammed the acceptable voltage range. The check engine light will turn on if the voltage exceeds the threshold. Other fault codes can also be stored depending on the severity of your problem. P0067 is closely related to the P0065 or P0066 codes.
What causes the P0067 Fault code?
P0067 may indicate a short circuit within one of the wires of the air-assisted injector circuit. The PCM that controls the air-assisted injection system could also have failed. In such cases, the PCM will need to be replaced.
- – A defective solenoid for an air-assisted injector
- – Circuit problems
- – Vacuum leakage from injector, clamps, or hoses
- – Defective fuse / relay
- – Defective PCM
What are the P0067 Malfunction Code Symptoms
- – Illumination at the check engine lights
- – Increased fuel consumption
- – When the engine is cold, it can be difficult to start
- – Engine misfire or stalling
How do I fix the P0067 fault code?
- – Replacing air-assisted injator solenoid
- – Replacing one or more fuel injections
- – Reparation or replacement of wiring that is related to the fuel injector system
- – Replacing your PCM
It is crucial to test parts in order to avoid costly replacements and high costs.
How serious is the P0067 Fault code?
This code can be categorized as moderately to severe. At normal operating temperatures, engine performance will not be affected. However, it will be difficult to start an engine that is cold. If the fault is left unattended, it can cause damage to parts like wiring, injectors, and system voltage. To avoid any further damage to your fuel system, it is important that the fault be fixed as soon as possible.
