Basically this means that an oxygen sensor in banks 1 and 2 detected a rich condition (too little oxygen in the exhaust).
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 include:
Make sure you are careful not to damage the MAF sensor, and make sure it's dry before reinstalling

Hey. How many miles on it. If over 100,000, it may need new O2 sensors but unlikely both would go out of spec at the same time. You will need to install a scan tool with data stream abilitys. The pressure regulator could be ruptured which will drastically richen up both banks. If no tool, locate the pressure regulator, usually on the right side at the end of fuel rail. Make sure the vacuum line is attached and pulls vacuum. Unhook the line. The motor should sound very different and then correct itself when hooking the line back up. If there is no vacuum at the line, check for a broken or cracked area. Never overlook the simple stuff. Also need to check coolant temp sensor accuracy. It can be in tolerance but still read incorrect coolant temp. There are numerous other items that will cause a rich condition but check these first. TJ.

There may be problem with the mass air flow sensor (very common with Volvo). This causes the fuel system to malfunction.
You may have noticed increased fuel consumption, loss of power and general 'lazyness'.
Better to take it to authorized Volvo service for a checkup/fix.
