PO204,205 are injector circuit malfunction,PO174 is a system lean code, PO175 is system rich code, PO138 is heated oxygen sensor bank1 sensor 2 circuit high voltage, PO158 is heated oxygen sensor bank2 sensor 2 circuit high voltage. This is a repair for your mechanic. When they fix the injector and o2 circuits the rich lean codes will also be repaired. Continued driving will ruin your catalytic converter. Good luck

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.

easy one.. when ever you have codes and want to know what they are..visit.. www.bestdirectorysolutions.com on the home page.. left side, scroll down and click on trouble codes... good luck sir

PO172 Bank 1 system too rich.PO175 Bank 2 system too rich. The tps may be bad. or the MAP sensor. They both control the fuel system.

(1) Check your air filter for needing replacement. (2) could be a defective positive crankcase ventilation (PCV) system. or (3) The Ox2 sensor is bad.

P0175 : That means your car is running rich in Bank2.

Could be your 02 sensor or your MAF sensor.

These codes mean system too rich, meaning too much fuel while running, I would check the vacuum lines and then clean the Mass Air Flow sensor (MAF), it should be located in line with the air intake tube from the air filter. Be careful not to damage the sensors internal components (use electrical cleaner or brake cleaner), and make sure it is dry before re-installation. Hope this helps, let me know.

Changed the air filter lately? Possibly defective O2 sensors, but I doubt it. If air filter and intake are clear, I'd check barometric pressure sensor and mass air flow sensors. Get a Haynes or Chilton's for $25 at Pep Boys for instructions on testing these componenets

po-120 is--tps/pedal position sensor A curcuit malfunction. po172 is---system to rich (bank 1). po120 means that the tps is out of adjustment or it is bad. for po172 after you repair tps, it may be ok, if not change front oxygen sensor,
