SOURCE: p0313 p0455 p0171 p0174 what

P0313 - Misfire Detected with Low Fuel
P0174 -System too Lean (Bank 2).
P0171 -System too Lean (Bank 1).

P0171 and P0174 mean "system too lean" for banks 1& 2, respectively. This means that 2 O2 sensors are reporting too lean. Since it is unlikely that 2 sensors would go bad at the same time, it is more likely an intake problem. The P0300 code indicates multiple cylinder misfires and doesn't necessarily relate to O2 sensors.

With your engine running, try to slowly and slightly remove your oil cap. There should be a slight vac, but if it's a very strong vac. and the engine stumbles hard when you remove it then it probably needs a "Crank case vent valve." Other places to look for air leaks is the air boot that "Ys" off at the throttle body and Idle control valve (follow your MAF back to your Intake and you will see it). The small hose on the boot that goes to the Idle control valve cracks on some older cars and allows "false air" in, causing your lean mixture faults.

If none of these give you anything, look at your MAF signal as the engine is running (operating temperature WITH THE A/C OFF). IF the MAF reads something other than 11-13 kg (I think it's KG) then you probably have a faulty MAF.

An easy way to find an air leak is with a can of carb cleaner, or break cleaner run the engine, then go around spraying stuff, and listen for the idle to rise up. spray on the intake boot, and around the hoses and such going to the intake.

Failed emissions with 2001 BMW 325i. Codes given were P0313, P0171 System too lean Bank 1, and P0174 System too lean bank 2. What do these codes mean?


Those codes mean the fuel to air ratio is to lean, not enough fuel. This is caused by quite a few things, most common is a intake manifold vacuum leak or other source (like hoses and the brake booster) A problem with the MAF (mass air flow) sensor can cause this as well if it is reading the incoming air volume wrong.
