When is the p2149 fuel injector Group B code active?
When is the p2149 fuel injector Group B code active?
The P2149 Fuel Injector Group B 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.
What causes a p2146 fuel injector supply voltage code?
Causes for this P2146 fuel injector group supply voltage code may include: Defective or damaged fuel injector(s) Damaged wiring harness Internal wiring malfunction Internal ECM issue Connector problem
What is the code for fuel injector Group B?
Code P0204 says “Injector circuit malfunction cylinder 4″ and code P2149 says”Fuel injector grp B supply voltage circuit open” I’m thinking problem could be a faulty injector or inject… Need more help with a P2149 code?
How to tell if there is an open in p2149?
One test I like to do to determine quickly if there is an open within a particular wire which would help with code P2149 is to do a “continuity test”. Setting your multimeter to RESISTANCE (a.k.a.: ohm, impedance, etc.), touch one end to one tip of the circuit and the other end at the other tip.

What is the fuel injector trouble code p2146?
Code P2146 is a major failure in the fuel injector voltage supply circuit and will cause the engine to run very rough and misfire.
What is the p2149 code on a Dodge 3500?
I have an 05 Dodge 3500 with 5.9 Cummins. I’m getting a code P2149 fuel injector group B supply voltage circuit/open. Anyone have any ideas for me? Truck still runs good until you put the hammer… Put the hammer down…Duh 5 people found this helpful. P2149 is for bank 2 injectors being shorted high or low.
What is the diagnostic code for fuel injector group a?
P2146 is a diagnostic trouble code (DTC) for “Fuel Injector Group “A” Supply Voltage Circuit/Open”. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation.
What is the Mil code for a fuel injector?
Some examples of distinctions with injectors: Bank 1, 2, etc., paired injectors, individual injectors, etc. The ECM illuminates the MIL (Malfunction Indicator Lamp) with P2149 and/or related codes ( P2150, P2151) when it monitors a fault within the supply voltage to the fuel injectors and/or their circuits.
