This code is for an open circuit for injector #1, this is the front injector on the drivers side. This can be caused by an open to the injector or the injector itself or the pcm. The first thing to do would be to check the connections for the left bank injectors, of they look ok, you will need to perform tests that require a scan tool that can perform injector electrical tests and activate certain pcm controlled pids.
I was mistaken, this will be the passenger side front injector, sorry about that.
Would you be able to give me a diagram showing the injector on the engine
Let me see if I can send you a picture.
The #1 injector is figure #4 in this picture.
Did you get the pictures ?
