P0279 - OBD Trouble Code

<<See All OBD Codes

OBD-II code decreased engine performance can be defined as cylinder 7 injector circuit low. There are special transistors in the engine control module which are known as “drivers” so that the fuel injectors can be turned on and off in the fuel injection system. If the powertrain control module would not be able to control the fuel injector, then it would set the P0279 fault code.

The error code P0279 will be stored by the powertrain control module when it would experience a low voltage situation that would involve a fuel injector for the number seven cylinder.

Generally, this code would mean that one of your vehicle fuel injectors is failing, which can happen because of a lot of reasons. There is a specific voltage spectrum for every vehicle make and model which is considered acceptable by the manufacturer’s standards which are predetermined.

This trouble code is generic, which would mean that it can apply to all the vehicles which are equipped with the OBD-II or the vehicles which are made since 1996 up to the present. The specifications on the definition, the troubleshooting steps as well as repairs can always vary from one vehicle make to another.

What causes this problem with the Cylinder 7 Injector Circuit Low?

• The wiring or connector that is associated with the fuel injector on the number 7 cylinder might be damaged
• The internal return spring inside the fuel injector on the number 7 cylinder might not perform properly
• Defects in the powertrain control module 

1. Fuel Injector - Do you remember when was the last time you got your car Fuel Injector checked up? A faulty Fuel Injector can cause a lot of issues like displaying P0279 code.
2. Fuel System - Poor Fuel System can cause a lot of difficulties, so why not get it replaced at time?
3. Engine Wiring Connector - Are there some faults in your Engine Wiring Connector? Don’t waste time and get them replaced or else P0279 code can turn up.
4. Powertrain Control Module - OBD Code P0279 can appear because of faulty Powertrain Control Module. Visit us and solve your problem.
5. Engine Control Module - Everything is fine with fuel injector and still P0279 code triggering? Then you must get your Engine Control Module checked.

It is essential to diagnose this fault code. Here are some steps which a mechanic should follow for diagnosing the problem that triggered a P0279 code to be stored:

• The first and the foremost step a mechanic would take would be to locate the fuel injector on the number 7 cylinder. You may have to remove the plastic engine cover so that you are able to gain access
• After that the mechanic would then test the fuel injector using the service information which has been given by the manufacturer
• Then it should be ensured by the mechanic that the wiring and connector associated with the fuel injector on the number 7 cylinder are in perfect working condition

Now if the cause of this fault code has not been located after the performance of these two sets:

• Then the car mechanic should use a high-tech scan tool to test the powertrain control module for some issues

Common Mistakes When Diagnosing The P0279 Code

• Failure in the fuel injection control module
• There can be some wiring issues
• Fuel injector might start failing
• Some failures in the powertrain control module
