P0202 is something wrong with cylinder 2 injector circuit malfunction. I would start with checking the wires on the number 2 cylinder making sure the connector is clean and plugged in. Also check and see if the spark plug is wet if it is dry off plug and put back in because it was not firing.

You mean P0202 , an what engine does yours have ? 2.6 L ,3.3 L , 3.6 L or 5.7 L ?
DTC P0201, P0202, P0203, P0204, P0205, or P0206
The engine control module (ECM) enables the appropriate fuel injector on the intake stroke for each cylinder. Ignition voltage is supplied directly to the fuel injectors. The ECM controls each fuel injector by grounding the control circuit via a solid state device called a driver. The ECM monitors the status of each driver. If the ECM detects an incorrect voltage for the commanded state of the driver, a fuel injector control DTC sets.
Test your fuel injector for cylinder #3 ! Do you know how to do that ?
You probably changed computers for nothing ! Check out this video on testing fuel injector circuits an checking computer driver that controls the injectors , Oh , by the way P0300 P0301 an P0302 are misfire codes , P0300 is a random misfire an the other two are for cylinders 1&2

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
Bad PCM


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

Transit pump code p0216 how can i fix this


P0216 DTC - Injection Timing Control Circuit Malfunction and this means the diesel fuel injection pump has a timing failure. This could be that the injection pump timing needs adjusted OR the failure is internal to the injection pump and therefore non-adjustable.

NOTE: If your vehicle is a Dodge Ram with Cummins engine then be aware that fuel delivery problems frequently cause this code. Prolonged fuel delivery problems can cause injection pump failure!

Symptoms of a P0216 DTC may include:
Low power
Crank, but no start
Hard start
Displays an intermittent stumble or miss
Engine may start and then stall
Engine may appear to drive fine but surge at idle


The most frequent cause of this code is a bad injection pump due to poor fuel delivery. Fuel delivery problems could be:
A plugged diesel fuel filter
An in-tank blockage
Air in the fuel due to a cracked in-tank fuel ine above the fuel level
Bad transfer (lift) pump
Injection pump out of time


Possible Solutions: First, simply check if your injection pump timing is adjustable. If so, check the timing and adjust if necessary.

If you think that you may have a fuel delivery problem, then check the lift pump operation. On Dodge Ram with the Cummins engine, the lift pump should produce about 45 oz of diesel in 25 seconds of operation. This can be performed by disconnecting the fuel hose from the injection pump and pumping the fuel into an approved container. Bump the engine over but do not start it. Then the lift pump will operate for 25 seconds. If the fuel is aerated, then check/repair fuel line and recheck.

With the fuel hose connected the fuel pressure should be 10psi. If the fuel delivery tests fail, replace the diesel fuel filter and recheck.

If it still fails then verify there are no restrictions in the fuel tank

Then replace the lift (transfer) pump. IT SHOULD BE NOTED that if this code surfaced after a routine fuel filter replacement or if you have any of the above symptoms after routine fuel filter replacement, then suspect the fuel transfer pump. This occurs because even a weak transfer pump can still provide enough fuel for the engine to run. But when the fuel system\'s prime is lost due to fuel filter replacement, it may not restart again without fixing the fuel delivery problem.

If you found your injection pump to be bad, the lift pump should be checked for operation to protect the new injection pump. This is because weak or low output from lift pump are common cause of injection pump failure. There are some aftermarket kits that can be purchased to warn the operator when the fuel pressure/volume drops to level that could damage the injection pump.

Hope this helps (remember to rating this free answer and leave a testimonial comments).

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.

Missing error code P0201


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.
