P005F - OBD Trouble Code

<<See All OBD Codes

Did you mechanic just tell you to replace the exhaust, turbocharger and your boost control module? Do you know the reason why he told you this? The reason behind this is very simple – The appearance of P005F Trouble Code. There might be some issues which those car parts and that’s why the P005F code would have been triggering up again and again. So, he asked you to replace all these parts to correct this major issue.

Have a look at some detailed information regarding P005F. The parameters for this generic code are very different as it totally depends upon the vehicle manufacturer. This code would generally set up if there is some issue with the turbocharger bypass system. The issue which can arise is that the bypass system may not be releasing enough pressure or sometimes no pressure at all. Unusual voltage signals from the boost controller circuit would inform the PCM that there is some sort of trouble with the bypass system. Your car may enter into a limp mode when the code would set up so that it can protect the engine constituents from getting destructed.

What causes this problem with the Turbocharger/Supercharger Boost Control?

• Leakage in the exhaust
• Defects in the turbocharger/supercharger
• Some sort of internal issue with the ECM (Engine Control Module)
• Defects in the Boost control module
• Faults in the boost pressure/ turbocharger position sensor
• Boost pressure/ turbocharger position sensor harness may be opened or shorted
• Bad electrical connection with the boost pressure/ turbocharger position sensor circuit

1. Turbocharger - Did you just see P005F code flashing? Then you must get your Turbocharger checked.
2. Supercharger - Did you just see P005F code flashing? Then you must get your Supercharger checked as soon as possible.
3. Exhaust System - Can a car survive in the absence of Exhaust System? The answer to this is a big NO. Then why not get your Exhaust System checked to see if it needs some replacement or not.
4. Turbocharger Actuator Position Sensor - Some issues with the Turbocharger Actuator Position Sensor can also be the reason why OBD Code P005F is flashing. You can always visit us to purchase top notch Turbocharger Actuator Position Sensor online.
5. Turbocharger Bypass Valve - There can be some defects in the Turbocharger Bypass Valve due to which P005F code may come on again and again. Make sure to replace it or else you may have to face some major issues.
6. Boost Control Solenoid Kit - Everything is fine with turbocharger/supercharger and still P005F code triggering? Then you must get your boost control solenoid checked.
7. Vacuum Hose Kit - Facing some issues with Vacuum Hose? Find top notch Vacuum Hose Kit online from us.
8. Boost Pressure Sensor - Did you just see P005F code flashing? Then you must get your Boost Pressure Sensor checked.
9. Turbo Boost Controller - OBD Code P005F can appear because of faulty Turbo Boost Controller.
10. Powertrain Control Module - There can be some issues with the PCM due to which you may see P005F code appearing over and over again. Visit us to buy best quality PCM online.
11. Engine Control Module - Are there some faults in your Engine Control Module? Don’t waste time and get them replaced or else P005F code can turn up.

It is very important to know the symptoms of an issue as only then you would be able to solve the problem. So that’s why we have listed out some major symptoms of OBD Code P005F here.

Common Symptoms

• An illumination in the Check Engine Light
• Decrease in the engine power
• Whining or rattling noises may start coming from the turbocharger
• Hissing noise may be heard if there is a boost leak
• There can be excessive or lack of boost pressure in the
• A lot of smoke can start coming out from the exhaust system

We have listed out some ways which would help you to correct the occurrence of OBD Code P005F. They are mentioned here as follows:

• You should try to replace turbocharger bypass valve
• The damaged vacuum lines should be repaired or replaced if needed
• The boost pressure sensor should be replaced
• Sometimes the wiring/connectors may be extremely damaged, so the best option would be to replace them with brand new ones
• Replace the boost controller
• The Powertrain Control Module should be replaced as quickly as possible

Very dangerous amount of heat is generated from the induction systems and it can also burn our skin if we will not protect it properly. That’s why the boost control solenoid should be visually located initially. Now once it is located, the other step is to make sure that its mechanical functionality is up to the par. The reason behind this is that it mechanically controls your charger and boosts pressure. It would be a good sign if you can manually move the lever from the solenoid to the charger housing. It may or may not be possible to do this thing in some systems. Adjustable levers are possessed by the solenoids which are very helpful in finding the “sweet” spot. This thing may vary from on manufacturer to another, so you must do proper research first of all. The module can be directly mounted to the boost control as it all depends upon the particular setup. Just make sure that no signs of water intrusion are found. If there is any sign or corrosion, water or some sort of damage, then the assembly should be replaced with a brand new one. Pay full attention to the harnesses which are directly going to the boost control solenoid.
