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

I suggest you begin by servicing the engine including checking spark plugs, spark power and testing the injectors, fuel pressures, delivery volume, etc., with a thorough visual inspection of pipes, wires and connections.

Once done, erase the codes and go for a drive and see what codes come back. If any comes back it will be time to begin serious fault finding...

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
Testing Fuel Injectors Fast PCM Driver Testing II without scan tool Did you just replace the PCM - engine computer ? Didn't test anything !

I would try disconnecting battery again. Disconnect both cables and touch them together for a few seconds. This will reset all modules. Wierd that you had so many codes after just disconnecting battery. Sometimes very hard to tell if ecm is bad.

I will give you what the codes mean and you can then work out what to replace.
code p0171 refers to system too lean--bank 1===causes intake / exhaust leak---AIR system---MAF/VAF sensor---fuel pressure/pump---injector/s---HO2s
code p0201 refers to injector 1--circuit malfunction===causes--- wiring--injector ---ECM
code p0202 refers to injector 2 --circuit malfunction===causes --wiring---injector--ECM
code p0203efers to injector 3 --circuit malfunction===causes---wiring--- injector --ECM
code p0204 refers to injector 4 --circuit malfunction===causes ---wiring ---injector ---ECM
code po321 refers to crank shaft position (CKP) sensor/engine speed (RPM) sensor---range / performance problem===causes---air gap---metal particle contamination---insecure sensor /rotor --wiring---CKP/RPM sensor.

Hi, these are taken from the data sheets

P1523 - electronic throttle system (ETS) - throttle valve sticking - probable cause = mechanical fault, ECM

P0204 - injector 4 - circuit malfunction - probable cause = wiring, injector, ECM

P0206 - injector 6 - circuit malfunction - probable cause = wiring, injector, ECM

hope that helps

P0204 - Injector Circuit Malfunction Cylinder 4http://engine-codes.com/p0204.htmlForum CodePossible causes- Fuel Injector 4 harness is open or shorted
- Fuel injector 4 circuit poor electrical connection

- Faulty fuel injector
- Faulty Engine Control Module (ECM) Help with thisWhen is the code detected?The P0204 is set if the Engine Control Module (ECM) is detects a low or high voltage drop or resistance at the injector 4.

This one could be tricky but i have an idea or two. First thing to check is the connections at the fuel injectors. Unplug them all one at a time and insure they are free of rust and moisture. Next..trace the injector wires through the harness and check for melted wires. If all the connection are good and there is no melted wires find the ECM under the hood. Its located on the firewall on the passenger side. Unplug the big connector and check for rust and moisture. Your model may have 3 connectors so check them all as well. Next grab all the injectors while the engine is running. You should feel them clicking. The ones that don't click are the culprits. After unplugging the ECM you might want to remove the negative termanal from the battery for 2 minutes, This will flash the ECM trouble code memory. Start the engine and see if the problem persists. Good luck
