Means that you should use a scan tool to reset the ECM or replace the ECM
check for correct voltage at the ecm
check for bad ground points
check for wiring harness and water in connections

    you never mentioned accident but yes
    anything that can spike the ECM will cause problems
    even accidently connecting jumper leads incorrectly can cause problems

Is there fusies goijg to you o2 sensor if so could that make my 2002 chev truck lack power got alot of codes po157 po101 po161 po 135 and po300 any help

yes check fuses for contact problems this is the one in the engine compartment also replace fuel filter check battery for being weak check fuel pressure and check for vacuum leaks also for code po101 replace air filter. the codes may say low voltage but what it really means is the time it takes for the o2 sensor to heat and switch lean can mean low voltage if it were high voltage we would check for a short circuit

I have a 1997 1500 with a 5.0 Im getting codes po143 po172 po175 and po300. Im not sure what the cause could be.

Code 300 is for a random miss.
172 and 175 are for the same problem - 172 is for a rich fuel mixture bank one and 175 is for the fuel mixture too rich on bank two.
Code 143 is for a rich mixture for sensor number 3.
All of the codes could be connected to a leaking injector or other fuel problem. Very seldom are all of the O2 sensors faulty at the same time.

On a 2004 dodge 1500 ram with a 5.7 are both downstream o2 sensors the same

Hi I am looking to find out if anyone else agrees that the metal part of the o2 sensers are the same only the plastic connector is different. So if you buy the up stream senser that is cheaper than the down stream one and splice your old connector to the new metal senser you have a fix.

I have a few error codes for my 2004 dodge ram hemi 1500 4x4. they are po172, po300, and po304.

The p0172 is due to an O2 sensor in the exhaust seeing too much oxygen, the po300 is a missfire present and p0304 is cylinder #4 missfire, check plug and wire to #4 and repair, this should also take care of the p0172, if a cylinder is missing it is just pump air into the exhaust thus causing the code p0172.

My 2004 Dodge Ram 1500 Hemi 5.7L V8 is running two codes PO175 fuel system rich 2/1 and PO131 O2 Sensor circuit 1/1 low does this mean I need new o2 sensors or what?

faulty O2 sensors will throw a lot of things out of whack so start there, allow diagnostic reboot, drive and check codes again...

The p0300 What does that mean? Basically this means that the the car's computer has detected that not all of the engien's cylinders are firing properly.
A P0300 OBD DTC code indicates a random or multiple misfire. If the last digit is a number other than zero, it corresponds to the cylinder number that is misfiring. A P0302 code, for example, would tell you cylinder number two is misfiring. Unfortunately, a P0300 doesn't tell you specifically which cylinder(s) is/are mis-
The p0430 What does that mean? Basically this means that the O2
downstream of the catalytic converter on bank 2 is detecting that the converter is not working as efficiently as it should be (according to specs). It is part of the vehicle emissions
