When to use check engine light code p0101?
The mass air flow (MAF) sensor measures the amount of air entering the engine. Check engine light code P0101 is set when the measurement of air entering the engine by the mass air flow sensor is outside of the manufacturer’s specified range.

What causes a mass air flow sensor to malfunction?
Possible Causes. Mass Air Flow Sensor (G70) faulty. Air Leak(s) after Mass Air Flow Sensor (G70) Excessive restrictions in the Intake/Exhaust System Dirty air filter, clogged snow screen, clogged CAT. Ground Spots corroded or Paint Residue. Wiring and/or Connections from/to Mass Air Flow Sensor (G70) faulty.
Is it worth replacing a mass airflow sensor?
You might be thinking of installing a new mass airflow (MAF) sensor to see if it’ll fix your engine driveability problems. But it’s not a good diagnostic approach to just replace the sensor without investigating. You can spend $100 or more on a quality airflow sensor and yet solve nothing.
What does faulty mass air flow sensor ( G70 ) mean?

What are error codes for mass air flow sensor?
For doing so you only need to connect your code reader and turn the ignition key on (engine off), a state usually known as KOEO. Common error codes include P0299 (if turbocharger is fitted), P0300, P0101, P0102 and P0171.
Can a bad mass air flow sensor trigger a check engine light?
Bad mass air flow sensor with no check engine light? Sometimes a mass airflow sensor can start to fail and even trigger engine error codes such as P0101 and P0102, without triggering a check engine light. There must be a problem with the mass airflow sensor circuit for the check engine light to illuminate.
What are the symptoms of a bad air flow sensor?
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. A bad mass air flow sensor is often the likely culprit if your car isn’t running as it should.
What causes the DTC p0101 MAF sensor to fail?
Depending on year, make, and model, DTC P0101 may have a number of causes. Here are some of the most common. Toyota / Lexus – The hot-wire MAF sensor is notoriously susceptible to oil contamination and aftermarket air filter contamination.
What is the error code on the MAF sensor?
I checked the error code using OBD2, and the code was P0101. I bought MAF sensor cleaner and a new air filter (the old air filter was very dirty). After cleaning the MAF sensor, I replaced a new air filer.
What’s the problem with my Altima MAF sensor?
P0101 – MAF Sensor Problem.. Hi. Everyone. MIL lamp for my 2013 altima 2.5S illuminated. I checked the error code using OBD2, and the code was P0101. I bought MAF sensor cleaner and a new air filter (the old air filter was very dirty). After cleaning the MAF sensor, I replaced a new air filer.
When to set the p0101 mass air flow code?
The P0101 code is set when the Powertrain Control Module (PCM) detects that the Mass Air Flow (MAF) sensor frequency is below a predetermined value. The Mass Air Flow (MAF) sensor measures the amount of air ingested by the engine.
What to do if your car has a p0101 code?
Check for damaged components and look for broken, bent, pushed out, or corroded terminals. Before replacing the mass air flow sensor, try replacing the air filter and cleaning the air flow sensor with low compress air or mass air flow sensor cleaner. Reset code and drive vehicle.

What should I use to clean my MAF sensor?
Use mass air flow sensor cleaner (DO NOT SUBSTITUTE FOR ANY OTHER KIND OF CLEANER) to clean out the MAF sensor. Do this by spraying each side of the MAF sensor for 3-5 seconds, waiting 10 seconds, and then spraying it again for 3-5 seconds.
What can a bad MAF sensor do to a Saab?
A bad mass airflow sensor can leave your Saab 9-3’s engine running rough, or even inoperable. A MAF sensor measures the density of the air entering the intake manifold.
Why does my Saab 9-3 idle erratically?
Idle Issues – Your 9-3 may run rich or lean when idling, or it may also idle erratically. A rich condition is when there is not enough air relative to the fuel in the air/fuel mixture. The exhaust color is usually darker when running rich.
