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.

First you need to clear the codes. If these codes are from before you did the work. The ECM still thinks it's bad. Then if they come up again start with one and work your way through.

My 2002 a-6 3.0 suddenly started running rough-engine light is on and blinks at 45mph. runs doggedly

Check oil and coolant levels (at the radiator cap) first. Run fault codes to find which sensor triggered the engine light . The light is to tell you that the engine is in danger of failure so do not dismiss the light as not important.. Hot smells mean that the engine is very hot and you may not have any coolant in the system to activate the temp light or gauge.

It is an interference engine and you will have bent valves . That will be the cause of your rough engine and lack of power. To test have a compression test done first before pulling the head

All 3 on one side. codes p0202 p0204 p0206. is this the ECM?

check injector resistance and pattern on a scope. if you have the proper power and ground it could be dirty injectors or the possibility of bad injector drivers in the computer.

DTC P2146

The ECM supplies high voltage to each fuel injector on the ignition voltage circuits. The ECM energizes each fuel injector by grounding the command circuit between the FICM (fuel injector control module) and the fuel injector. The FICM monitors the status of the ignition voltage circuits and the fuel injector command circuits. When a fuel injector circuit condition is detected by the FICM, all of the fuel injectors will be disabled. If a circuit condition is detected on a fuel injector circuit for cylinders 1, 2, 3, or 4, DTCs P0201, P0202, P0203, P0204 will set, along with DTC P2146. So something is wrong with your injectors or their wiring.

2007 dodge 3500, 5.9 cummins,engine light on, fault code p2146, running rough

It's a code that signify's you have a voltage circuit problem with one or more fuel injectors. When a problem is found with the fuel injector circuit it affects fuel delivery on all the injectors and that is why it is running rough.

Good Luck

Check engine light on did check and said injector cercuit open cylinder #2 car is running rough how do you fix it?

Code P0202??
Most of these problems occur because of electrical: wiring or ground problems. Before throwing money out and chasing the problem:
Check the wiring harness for Cylinder #2 Fuel Injector. Especially check the Ground wire connection on the intake manifold.
Is the Battery fully charged? The sensors and control unit runs off the battery. If the battery is not fully charged the engine will run rough.

Check these first and get back with me if it does not work.

95 Jeep Cherokee 0 compression in #2 cylinder.

If you have a 0 reading from cylinder 2 that means there is no compression from it and you need an enfine rebuild.It seems that there had been damage to the engine.Have it hooked up to a computer and check diagnostic code.Overheating of an engine can be very costly and damaging, rememeber that always.

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.
