04 intrepid p0202 injector open circute check all options do I need new pcm

P0202
Trouble Code: P0202 (4.7L V8 VIN N Auto)
INJECTOR #2 CONTROL CIRCUIT the coil inside the injector 2 is bad. the PC fails so see the inductive EMF kick back from the coil. (oem injectors only)
the wires to injector 2 are bad
the PCM is bad.
the SM states (*and is correct)

• INTERMITTENT CONDITION
• ASD RELAY OUTPUT CIRCUIT
• FUEL INJECTOR bad.. or wrong one used, non OEM fail easy.
• FUEL INJECTOR DRIVER CIRCUIT OPEN
• FUEL INJECTOR DRIVER CIRCUIT SHORTED TO GROUND
• PCM

the PCM is tuned to use only OEM injectors,.
THE PCM is very smart in this regard, it works kinda like RADAr
THE PCM SENDS A PULSE TO THE INJECTOR AND IT SIGNAL BOUNCES BACK, IF this signal is weak the injector is dead or wrong one there. use OEM injectors if SAVVY to this magic,

or swap say injector 1 and 2,
if injector 1 fails now not 2 then the injector in 1 is bad, or wrong kind.
easy no ? swaps

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.

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.

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

P0202 Cylinder 2 Injector Circuit Malfunction


The above link explains what code P0202 indicates. The problem could a bad injector or wiring to it or the plug connected to the injector, First thing is check the wire connector at the injector.

did you google these codes?

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.

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

202 Injector problem #cylinder 302 misfire #2 cylinder bad fuel injector, wiring going to it. Your PCM could be bad I don't think so Check coil on # 2 firing. Check # 2 plug make sure gap didn't close when you put it in. Bad injector or Coil or plug

The ground wire from the injector to the pcm is open. The injectors share the same power wire but the pcm grounds each one individually to fire.
