This would be the opposite of a lean condition, which’ll throw P0171. The P0172 code on a Subaru Forester will often be thrown if the fuel injection system is not operating properly. Typically the code will be triggered by a rich condition in the engine. There aren’t usually any drivability issues associated with P0172.
What is the trouble code on a Subaru Forester?
A common trouble code with the Subaru Forester is P0172. This code number references a number that is given to you when you plug your car into a OBDII scanner. It’s not the most complicated OBDII trouble code to diagnose. It is also one of the most common.
Why is my p0171 system Lean code not working?
Change the plugs and oil about a month and a half ago and got a maf sensor error and get a P0171 system lean code after resetting the ECU. I’ve been troubleshooting since then but can’t seem to get the P0171 ironed out. The cel only pops at idle and the car runs great through the power band. Here’s what I’ve already done.

It’s not the most complicated OBDII trouble code to diagnose. It is also one of the most common. It means that the motor is running with a rich condition. P0172 is thrown when the oxygen sensors detect that the air fuel mixture is too rich.
What to do if your Subaru has a p0171 code?
If there are no intake leaks, the next step is to replace the air filter and clean the air flow meter. If the problem persists the front oxygen (O2) sensor may need to be replaced. The cost to diagnose the P0171 SUBARU code is 1.0 hour of labor.
What does the code p0171 stand for?
P0171 is an OBDII trouble code. The code technically stands for: The code is thrown when the oxygen sensors detect that there’s not enough oxygen in the exhaust system. This is commonly referred to as a “lean” condition.
What to do if your air filter is p0171?
Check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins. If the P0171 is combined with the P0174 code, it’s very likely that the problem is caused by an intake leak. If there are no intake leaks, the next step is to replace the air filter and clean the air flow meter.
What causes the p0171 code on a Subaru Forester?
Vacuum Leaks – With the Subaru Forester, one of the most common cause for the P0171 code to show is a vacuum leak. Take a look around and see if you can find the vacuum leak.

What causes a Subaru Forester O2 sensor to go bad?
Subaru Forester O2 Sensor Mass Air Flow Sensor – The mass air flow sensor calculates the volume of air entering the engine. If it has gone bad, the air fuel mixture will be off and the P0172 code will show. Bad Fuel Injectors – If you have one or more fuel injectors that have gone bad that can certainly cause the air/fuel mixture to go bad.
