P0267 - OBD Trouble Code

<<See All OBD Codes

The fault code P0267 is an OBD diagnostic code which would indicate that the engine control module has detected the cylinder number 3 injector circuit having a high resistance open circuit or shorted windings. This trouble code can be defined as cylinder 3 injector circuit low.

This fault code would be triggered up when the engine control would detect a low voltage in the fuel injector 3 Circuit. In case of normal conditions, the fuel injectors would be turned ON and OFF by the engine control module in the fuel injection system. 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. This can happen because of a lot of reasons and the mechanic should diagnose the specific cause for this code.

What causes this problem with the Cylinder 3 Injector Circuit Low?

• The fuel injector on the number 3 cylinder might have a broken or weak internal return spring which could cause decrease in the reference voltage level
• The wiring or connector which is associated with the number 3 cylinder could be having or causing a connection issue and connection issues may also cause voltage levels to decrease or become inaccurate
• The powertrain control module can have some issues

Here are some steps which you should follow in order to diagnose this fault code:

• Diagnose this trouble code by first locating the number 3 cylinder fuel injector
• Now once the fuel injector on the number 3 cylinder has been located, the mechanic would test the fuel injector using the manufacturer’s suggested procedure. This test will reveal if the internal spring has failed due to the reference voltage that is produced by the fuel injector during this test
• Then the wiring and connector that are associated with the fuel injector on the number 3 cylinder should be carefully checked for damages

After these tests have been performed and the problem has still not been located, then there is surely some issues with the powertrain control module and would be tested by the mechanic. Once a determination has been made by the mechanic, he would share this information with the owner of the vehicle.

Common Mistakes When Diagnosing The P0267 Code

• There can be some defects in the fuel injector
• Faulty or corroded Fuel Injector, wiring, or connections
• Issue of clogged fuel injector
• There can be dirt in the fuel injector
