As such they lack a mechanical carburetor and instead split the function of the carburetor into three parts, namely the Air Flow Meter in the air cleaner box, the throttle body and the fuel injector. The air flow meter uses a flapper vane and temperature sensor to detect the amount and ...
5/8/2019· A bad mass airflow sensor can leave your Toyota Tacoma’s engine running rough, or even inoperable. A MAF sensor measures the density of the air entering the intake manifold. It passes this information onto your Tacoma’s ECU. The ECU uses this information along with other sensor data to control the amount of fuel that enters the combustion chamber. If you do determine that you need a …
15/10/2019· Only show this user. If you have changed over to an aftemarket "high flow" filter that is oiled, that likely is the problem. You should be able to clean the sensor and be good to go. I fouled mine then went back to the "correct" stock filter, cleaned the sensor and haven''t had a CEL return.
27/7/2014· SOURCE: have p0130 and p0133 codes 98 toyota tacoma. check the mass air flow sensor there maybe dirt on the filiment inside the sensor causing false readings. cleaning or replacing it may make the codes go away. Posted on Nov 18, 2009
22/10/2018· 03/31/2021 10/22/2018. The symptoms of a bad mass air flow sensor include low engine power, poor fuel economy, an engine that won’t start, a check engine light on the dash and a gas smell from the exhaust fumes.

P0171: This means that the oxygen sensor has detected a lean airfuel ratio. This can be caused due to a vaccuum leak or a problem in the HO2S circuit or the HO2S (Heated Oxygen Sensor) itself. (Bank one Sensor one). This is commonly located along the exhaust pipe. It could also be a bad Mass Air Flow sensor or a bad Engine Coolant Temperature ...

3/7/2019· If it''s a V6, then you have 4 O2 sensors. 2 on bank 1 and 2 on bank 2. If the O2 sensors on bank 1 read that it''s running lean then it will pop the code for Bank 1 and vise versa. Banks are just sides of the engine. Cylinders 1,3,5 (bank 1) are on one side while 2,4,6 (bank 2) are on the other. Russianman92, Jul 3, 2019.
