you'll notice on your valve cover gasket there is two connectors.. the one up front is your 1-3 the one in the rear is your 4-6... you can remove your valve cover and check the connections from the injector connectors to the
connectors on the valve cover.. check for an open.. however you could also have a fault internally in 1 of your injectors in that bank as well.. hope this info helped..

The check engine suddenly came on. Displaying p2146 code and p0202 code. Engine running rough and lacks power. It has done this approximately 6 times in the last 18 months. Recovers after a while. ...


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.

I have a dtc code of 2146 and can't find out what it is


Are you sure it isn't P2146? If it is P2146 it is Injector-group A, supply Voltage-open circuit. Possible causes-Wiring, engine control (EC) relay, injector.

P2146 and p0202 codes are posting


P0202 = Injector Circuit Malfunction - Cylinder 2
P2146 = Fuel Injector Group A Supply Voltage Circ/Open

Looks like either bad injector cylinder #2 or maybe an injector wire disconnected or shorted out.
