It is an injector malfunction on cylinder #1 and #2. Below average fuel pressure, clogged fuel filter, defective fuel reg., injector and wiring, water in fuel, spark plugs and wires, could cause your problem.

What does code P0202 on a 2006 Chevy Cobalt? It says "injector ckt open cylinder 2" but I have no idea what that means! ????

Well you either have a defective injector connector or wiring to it or the injector coil is an open circuit. Swap the injector to a different cylinder and see if that cylinder triggers a code or the code is still for cylinder #2, if triggers a new code the injector is defective, if the same code comes back after being cleared then you have either a bad injector connector or the wires from the PCM are open somewhere. You really need a full function scanner to make this job much easier.

How to fix 2007 chevy cobalt with error code p0202

DTC P0202:Fuel Injector #2 Control Circuit .You could have an open in the wiring or in the fuel injector coil windings ! Check for voltage at the pink wire . The other wire comes from the PCM , a transistor inside the pcm turns the injector on an off by grounding the circuit . You can test this by hooking up a test light to battery positive an the other pointy end touch to a T pin probed into that terminal at the PCM . With engine cranking the test light should flash . You should also ohm check injector coil ! the resistance of each fuel injector should be 11-14 ohms.

#1 cyl. miss with a/c on

Code 202 is for an open circuit for the number two fuel injector.
You should have power on one side of the injector an a ground signal from the PCM on the other.
Code 301 is for a miss on cylinder one which could be several things including the plug, coil, wire, or injector.

Code's 202 and 302

Both fault codes walk together, the first generated the second...

DTC P0202 - Cylinder 2 Injector Circuit Malfunction
P0202 means that the PCM detected a fault in the injector or the wiring to the injector. It monitors the injector and when the injector is activated, the PCM expects to see the voltage pulled "low" or close to zero. When the injector is switched off, the PCM expects to see a voltage that is close to battery voltage or "high". If it doesn't see the expected voltage the PCM will set this code. The PCM also monitors resitance in the circuit. If the resistance is excessively low or high it will set this code.

The symptoms for this code will likely be a misfire and a rough running engine. Poor acceleration. The MIL will also be illuminated.

The causes of a P0202 engine light code could be any of the following:
Bad injector. This is usually the cause of this code but doesn't rule out the possibility of one of the other causes
Open in the wiring to the injector
Short in the wiring to the injector

DTC P0302 Code - Cylinder #2 Misfire
A P0302 code means that the the car's computer has detected that one of the engine's cylinders is not firing properly. In this case it's cylinder #2.

Symptoms may include:
the engine may be harder to start
the engine may stumble / stumble, and/or hesitate
other symptoms may also be present

A code P0302 may mean that one or more of the following has happened:
Faulty spark plug or wire
Faulty coil (pack)
Faulty oxygen sensor(s)
Faulty fuel injector
Burned exhaust valve
Faulty catalytic converter(s)
Running out of fuel
Poor compression
Defective computer

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.

2002 durango code P0202 troubleshooting

You problem is with your number 2 cylinder's - injector circuit. Take it to a shop and have them check the wiring. Unless you can check the wiring yourself. The fuel injectors are tricky and really on the interior of the upper engine compartment. If you're good with cars, go for the dissassembly, otherwise it will take a few bucks to have them check the fuel injector. Wish i had better news.
