What to do if your injector code is p2149?
If the vehicle had only injector circuit codes for P0202 or P0207 (with bank shutdown P2146 or P2149), and the wiggle test induces a P0202 or P0207 to reset, use bulletin number 05-06-04-047B to repair the injector connectors and install the injector harness support kit.
What is the p2146 fuel injector group a circuit / open code?
The P2146 Fuel Injector Group A Circuit/Open code is active when the ECM detects a open or malfunction within the fuel injector’s supply voltage circuit. What is the severity of this DTC? Pretty severe I would say. In the field, we call a lack of fuel in the mixture being burnt, a “lean” condition.
Is the p2149 code a FICM problem?
I don’t know how true this is but its posted a lot. If the vehicle set a P2149 by itself and it did not also set a p0202,p0203,p0205,p0208 then it is an internal problem in the ficm. You did not mention that you actually checked this common LLY problem.
