What is a fuel injector Group b Supply Voltage circuit open?
This OBD-II code is defined as a Fuel Injector Group “B” Supply Voltage Circuit/Open, it is set by the Powertrain Control Module of the vehicle. When the PCM module notices that one or both of the fuel injectors in a group aren’t functioning as needed it will set this code.
What does code P2149 mean?
Fuel Injector Group
OBD-II Code P2149 is defined as a Fuel Injector Group “B” Supply Voltage Circuit/Open. The engine computer (PCM) controls the signal to the fuel injectors in groups of two. If the PCM detects one or both of the fuel injectors in that group are not functioning properly, the PCM will set code P2149.
How do I fix error code P2146?
What repairs can fix the P2146 code?
- Replacing the ECM for bad injector drivers.
- Repairing an open or short in the injector wiring or connector.
- Replacing a shorted injector.
- Replacing the injector harness.
What is Injector Group A?
The group letter “A” in this code is used to distinguish what exact circuit the fault is referring to. 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 fuel injector group a supply voltage circuit open?
The P2146 is defined as Fuel Injector Group “A” Supply Voltage Circuit/Open. Your vehicle’s Powertrain Control Module controls the signals that go to the fuel injectors. These go in groups of two, if it detects that any of the two fuel injectors in that specific group is not working properly it will set the P2146 code.
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 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.
When is the fuel injector group a code active?
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?
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.
