    Check Engine Light P0172 P0175

    Well.. I just recieved touble codes from my 2003 P71

    P0172 P0175

    It seems my system is too rich in bank No.1 and No.2

    Wtf does this mean?

    It means that the front oxygen sensors are reading too rich (basically not the right ammount of oxygen in the exhaust).

    here:

    Bank 1 = DTC P0172 (rich)
    Bank 2 = DTC P0175 (rich)
    Check intake air system for leaks, obstructions and damage.
    Check air cleaner element, air cleaner housing for blockage.
    Verify integrity of the PCV system.
    Check fuel delivery system and filter for restriction.
    Check for vacuum leaks

    Basically the diagnosis is looking at the evaporative emmisions system as well as the o2 sensors as possible causes.

    I'm not going to be able to tell you exactly what it is because I do not have your vehicle with me to be able to go through the tests that the shop manual is outlining.

    It could be as simple as a clogged air filter or clogged fuel filter. When were these last serviced? It could be a vacuum leak (although those typically show the lean variant of those codes).

    Basically what you need to do, since you obviously do not have access to the proper diagnostic equipment or materials is take it too a dealer. They will charge you 1 hour of labor for diagnosing what is the root concern, and then they will tell you what's wrong, with a quote for labor and parts.

    Sorry I cant give you a "bam, it's this".
