What happens when the MAF sensor goes bad?
If the MAF sensor has gone bad, it’ll trigger the check engine light and provide an OBDII trouble code. This is great because it helps you narrow down the problem. The two most common trouble codes in relation to the MAF sensor are:
Can you replace a mass airflow sensor without investigating?
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. But you can learn how to troubleshoot a MAF sensor in a few steps following this simple guide. the most common problem affecting MAF sensors (and what to do about it),
Where is the connector for the MAF sensor?
Connect your meter’s red lead to the B+ terminal on the harness connector (the one leading to the computer). Consult your vehicle repair manual to identify wires, if necessary. Connect your meter’s black lead to the ground (-) pin on the sensor connector.
What does the MAF sensor on a Ford Ranger do?
A MAF sensor measures the density of the air entering the intake manifold. It passes this information onto your Ranger’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 new mass airflow sensor, they aren’t too expensive.
Is there a temperature sensor on the MAF?
The MAF also incorporates an internal intake air temperature sensor which measures the temperature of the intake air. The first indicator that you might have a problem with the MAF is the presence of a check engine light (CEL) on your dashboard.
Can a bad MAF sensor cause a bad transmission?
You may have a bad MAF sensor if you notice one or more of the following symptoms: On some vehicle models, the MAF sensor also informs the computer about air intake temperature and engine load (to control some automatic transmission functions). So a bad MAF sensor on these cars can cause an even wider range of symptoms.

What does the code p0101 on the MAF sensor mean?
If the signal from the MAF sensor is lower or higher than expected, the ECM detects a fault and stores the code P0101 in its memory. In many cars the MAF signal is used to determine the shift pattern of the automatic transmission. Often, if there is a problem with the MAF sensor, the automatic transmission may shift differently.
If the MAF sensor has gone bad, it’ll trigger the check engine light and provide an OBDII trouble code. This is great because it helps you narrow down the problem. The two most common trouble codes in relation to the MAF sensor are: There are other codes related to the mass air flow sensor as well, but these are the most common ones.
What is the error code for MAF high input?
Table of Contents. Error Code P0103 is defined as MAF (Mass Air Flow) sensor or VAF (Volume Air Flow) sensor high input. Basically, this means there’s a problem with the MAF sensor circuit, as it receives a voltage (air flow) significantly higher than expected.
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 is the code for mass airflow sensor?
P0102 is the general code for a problem with the Mass Airflow (MAF) Sensor having a low voltage output to the Engine Control Unit (ECU).
What is the error code for a MAF sensor?
Basically, this means there’s a problem with the MAF sensor circuit, as it receives a voltage (air flow) significantly higher than expected. This error code is often associated with P0100, P0101, P0102 and P0104.
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 is the code for mass air flow sensor?
This Code’s full read out is: P0101 – Mass Air Flow Sensor Circuit Range/Performance. The engine computer uses the MAF sensor signal to determine how much fuel needs to be injected to meet the proper air-fuel ratio.
Why does my car have a bad MAF code?
This code is most commonly caused by a dirty, obstructed, or faulty MAF sensor, but can also be caused by issues including: Damage to the intake boot; Vacuum leaks; Clogged or improperly installed engine air filter; Clogged-up cat converter or restricted exhaust
