Yes, all po codes are a default code, you need to reset the computer by removing the positive cabel for 10 mins.

Toyota Corolla Code P0171 Check Engine light


Code P0171 on Toyota Corolla Q: What could cause the code P0171 on 2002 Toyota Corolla? A: The code P0171 reads "System Too Lean (Bank 1)". This means that the air-fuel mixture coming in to the engine is too lean, or there is too much air and too little fuel. This could be caused by a number of reasons, such as bad airflow sensor, vacuum leaks, low fuel pressure, clogged fuel injectors, etc. To know exactly what caused the problem, your mechanic can do a few tests.
From my experience, the airflow sensor problems are fairly common; sometimes the sensor just gets dirty and gives false air flow readings causing lean condition. Again, your mechanic can test it.
If the airflow sensor is causing the lean condition, it will need to be replaced. If the sensor is just dirty, your mechanic may suggest to clean it (cleaning the airflow sensor is very delicate procedure) as a temporary solution - sometimes this could work.

P0171 code


A code P0171 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 may 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 downstream of the MAF sensor

Possible cracked vacuum or PCV line/connection

Faulty or stuck open PCV valve Failed or faulty oxygen sensor (bank 1, sensor 1)

Sticking/plugged or failed fuel injector Low fuel pressure (possible plugged/dirty fuel filter!)

Exhaust leak between engine and first oxygen sensor

2000 Toyota tacoma with code P0171.


You don't say if it is a 4 cyl or 6 cyl engine.
The code means the O2 sensor is telling the computer the engine fuel mixture is too lean and the computer can not make the injectors provide enough extra fuel to make the sensor go rich.
Reasons can be a faulty cooling thermostat, low fuel pressure, vac leaks, exhaust leaks, and other engine problems.
