Question about Dodge Ram 2500
The error code p2146 says fuel injector group A supply voltage circuit/open problem.The p2146 error code is related to the wiring in the valve cover that going to the injectors.It is part of the gasket and comes as an assembly.The wiring/gasket assembly for the valve cover is the most common cause for this problem but you disconnect the injectors and check ,if the code comes up again then injectors are also faulty.
you will need to remove and install valve cover to test each injector.
For this one at a time, disconnect both wires from each injector and insulate the terminal ends so the circuit will not short to ground connections.
And for the error code P0202 the code says :-- Injector Circuit Malfunction - Cylinder 2. Its #2 injector circuit malfuction.Looks like either bad injector cylinder #2 or maybe an injector wire disconnected or shorted out.
---------- Check and possibly clean the connector on the injector and the connector itself.
It might just be loose.And that is causing this errors. ------- Keep updated with any more query.Thanks.
