They are both thrown when the oxygen sensors detect that there is not enough oxygen in the exhaust. P0171 and P0174 occur when the air/fuel mixture on the vehicle gets too lean. It could be getting too much air (think vacuum leak, EGR problem, or mass airflow sensor) or it is not getting enough fuel (bad injectors, weak fuel pump, dirty fuel filter, bad fuel pressure regulator). There are a few reasons that a vehicle will get a lean condition.

Is there a way to check the mass air flow sensor readings at home? Of course, for example, here we used the free Torque app to measure the mass air flow sensor readings at different RPMs (in the photo). Read more: Vacuum leaks: common sources, symptoms, repairs. That's why mechanics use a known-good sensor to compare the readings. Vacuum leaks affect air flow sensor readings too. A clogged up air filter or plugged catalytic converter can also cause lower air flow sensor readings. Low mass air flow readings do not mean the sensor is bad. The air flow depends on the engine volume, so a V6 or V8 engine will have higher readings. Of course, different engines will have different readings. In some rare cases a bad sensor may show higher readings. A contaminated or bad air flow sensor will, in most cases, show lower air flow readings than a known good one. Often mass air flow sensor readings are measured at idle, 1,000 RPM, 2,000 RPM and 3,000 RPM. Mass Airflow Sensor (MAF) readings of a 2.4L 4-cylinder engine at different RPMs. They compare the readings to the specifications or to the readings of a known-good mass airflow sensor. Mechanics measure the amount of air flow (mass air flow sensor readings) at different RPMs. In modern cars, the only way to test the mass air flow sensor is with a scan tool. Trouble codes P0171 System Too Lean (Bank 1) and P0174 System Too Lean (Bank 2) are also often caused by a bad or contaminated mass air flow sensor. P0104 - "Mass Air Flow Circuit Intermittent" P0101 - Mass Air Flow Circuit Range/Performance P0100 - Mass Air Flow Circuit Malfunction The following trouble codes are usually associated with a mass air flow sensor: This trouble code can be retrieved with a scan tool. When the air flow sensor signal varies from the expected range, the PCM records a fault and stores the corresponding trouble code, illuminating the Check Engine light on the dash. In addition, a faulty mass air flow sensor might cause the Check Engine or Service Engine Soon light to come on.Ī problem with the air flow sensor could also alter the shifting pattern of the automatic transmission. As a result, a bad mass air flow sensor causes various driveability problems, including a no-start, stalling, lack of power and poor acceleration.
