View User's P0171 Toyota Yaris. Hello everybody, Toota have a problem with my Yaris Made in Japan. The code appears only on the highway. I have cleaned the MAF sensor, Replaced the lambda sensor after the cat Toyota said that the first one is ok.
I have checked for leaks but i have not disassemble the intake manifold. I have purchased a Delphi OBD reader and i have checked the values between my 2 yaris. At 80kmh the first O2 sensor oscillate between 0,8 and 0,2v - The second is around 0,7v.
I have checked my spark plugs which are pretty white, Yarid i'm assuming that the engine is really running lean. The first cylinder and coil is really dirty around the spark plug like if the spark plug was leaking? This car made a lot of highway 70 km at kmh and overheated once. The car has km on it.

Oftentimes, a P means that your Toyota is having trouble with a dirty or faulty mass airflow (MAF) sensor, or a vacuum leak downstream of the MAF sensor (perhaps in the PCV line or in the valve itself). Of course, this code can also signify a bad O2 sensor in bank 1.
