Hi my name is ***** ***** I'd like to assist you. Can I please get the engine serial number?

Expert:  Geoff replied 1 year ago.

There are several causes for this code, including a bad injection control valve stator and a failed injection control valve. Inspecting these components involves several resistance checks. If you would like, I can upload a copy of the steps and resistance values you need. Would this information be helpful?
