Ok the codes po300 is telling you that you have a misfire on diferent cilinders, and the 201, 203, and 205 is telling you then the fuel injector number 1,3,and 5 have a problem, if you know where the injectors are, you can buy a little knoid light to see if the computer is pulsing the injectors with the car runing, but most likelly you are going to need to replace all the injectors, because when one goes bad it is recomended to replace all of them, they are between 35 to 95 dls each, but b4 repalcing any parts, make sure to have it chek to make sure if the injectors, or the circuits feeding the injectors is the problem. good luck and i will apreciate the ranking. and the misfire is caused by bad or inoperative injectors, bad spark plugs, or plug wires. but in this case seems to be injector problem.

First codes were 201 300 301 put in reman comp. codes were202 300 302 another reman comp code is 203. are the remans bad or other problem


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

How can I be sure if my PCM is bad???


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.

you may have bad fuel in the vehicle..I would put fresh fuel in the vehicle and add some octane booster to the fuel also with a bit of injector cleaner..then get all the codes removed..

Your vehicles computer should have the malfunction codes stored in it.

Some mechanics will check the codes for you. And some auto parts stores offer the service as well.

Trouble codes p0201 p0203 p0300 p0336


Start with the replacement of the Crankshaft position sensor to address the P0336.
The faulty crankshaft position sensor may be causing the P0201 which is a fuel injector failure to injector #1 and the P0203 which is a injector failure to the injector #3. The failure to the injector will cause the P0300 DTC code which is a code for multiple misfire.
The crankshaft sensor sends signals to the ECM which then would command the injector to pules open and close and the duration of time. If the ECM does not get the right readings, then it's not going to know when to command the injectors to activate.
Start with the Crankshaft sensor (CKP)and then check the injector wires and injectors it self after the (CKP) has been replaced if problem still persists. Good luck and keep me posted, be glad to help you get your car running 100% again soon.
