This means your oxygen sensor is reading problems with your fuel/air mixture. May consider in replacing the oxygen sensor, the one before the catalytic converter.

Trouble code PO172


Code 172 means the fuel mix is too rich on bank one. If you have a 6 cyl engine there is only one bank of cylinders. The problem could be the O2 sensor or a leaking injector among other things.

Need to solve po172 error code


P0172 - System Too Rich (Bank 1)
Basically this means that an oxygen sensor in bank 1 detected a rich condition (too little oxygen in the exhaust). On V6/V8/V10 engines, Bank 1 is the side of the engine that has cylinder #1.

Note: This DTC is very similar to P0175, and in fact your vehicle may show both codes at the same time. You will more than likely not notice any drivability problems, although there may be symptoms such as a misfire.

A code P0172 may mean that one or more of the following has happened:
* The MAF (Mass Air Flow) Sensor is dirty or faulty. Note: The use of "oiled" air filters can cause the MAF to become dirty if the filter is over-oiled. There is also an issue with some vehicles where the MAF sensors leak the silicone potting material used to protect the circuitry.
* There could be a vacuum leak.
* There could be a fuel pressure or delivery problem

Hope this helps; remember to rating this free answer.

P0172 and P0128 Error Code 2003 Trailblazer 4WD


PO172 means that an oxygen sensor in bank 1 detected a rich condition (too little oxygen in the exhaust). I would replace the thermostat first. The computer could be injecting too much fuel because it thinks it never gets to operating temperature. That may keep the light off.

Check engine light on


P0101 : Mass air flow censor, Air intake is blocked or the sensor is nackered.
P0172: System too rich bank 1. There's too much fuel, probably to do with the air fuel mix. If you sort the air flow meter that'll sort the two.
