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

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

Possible Solutions

Inspect all vacuum and PCV hoses, replace if necessary
Cleanthe MAF sensor. Consult your service manual for it's location if you need help. I find it's best to take it off and spray it with electronics cleaner or brake cleaner. Make sure you are careful not to damage the MAF sensor, and make sure it's dry before reinstalling
Inspect fuel lines for cracks, leaks, or pinches
Check the fuel pressure at the fuel rail
Check the fuel injectors, they may be dirty. Use fuel injector cleaner or get them professionally cleaned/replaced.
Check for an exhaust leak before the first oxygen sensor (this is unlikely to cause the problem, but it is possible)

SOURCE: check engine light on,running rough code P0172

When I see all these codes i instantly think of two things. Vacuum leak especially intake manifold gaskets and Mass air flow sensors. Spray the engine with carb cleaner when its running and see if you get it to rev up,run rough or run different. Next unplug the MAF and drive the car, see if it runs normal.

SOURCE: 2003 VW Golf - O2 Sensor?

Honestly it is not very expensive to replace, but it is not extremely important. What it does is measure the oxygen/fuel level coming out of the engine. This tells the computer that the engine is either using the right air/fuel mixture or allows the computer to change the mixture slightly to allow the car to run properly. You could pull the sensor out and clean the terminal as it usually has alot of carbon build up due to its location, but this is normally a temporary fix. I hope this helps you with your problem.

Go after the Egr valve, if its sticking then there is a vacumn leak.

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.

Vacuum leak somewhere.
Possibly could be the O2 sensor (the one before the cat up front).
I'd search for a vacuum leak since you may have rattled something loose.
