What does mass or volume air flow circuit low input mean

Diagnostic trouble code (DTC) P0102 isn't in every vehicle's code library, but whenever it appears it means “Mass Air Flow (MAF) Circuit Low.” The code is set when the ECM/PCM perceives a problem with the mass airflow (MAF) sensor's performance. The MAF sensor is mounted between the air filter and the throttle body.

What causes mass or volume airflow circuit?

The mass airflow (MAF) sensor is a device that is mounted on the air intake. Its job is to measure the density and, therefore, the volume of filtered air that is drawn into the engine. When the PCM perceives the sensor or its circuit is malfunctioning, OBD-II code P0101 is triggered.

Can you drive a car with a bad mass air flow sensor?

Yes, you can drive within such a sensor situation, but you can ride a car or truck for a specific duration. ... The bad mass airflow sensor problems can cause different drivability issues. The drivers can easily experience the lack of power in the engine, no-engine start, poor acceleration, and more during the drive.

Can I drive with code P0101?

The P0101 code will not prevent the car from driving but it is advisable to check it out as soon as possible. ... Sustained driving can cause internal problems in the engine. If the engine warning light came on immediately at start up, the OBD- II system can be reset and the vehicle will operate normally.

Can a dirty air filter cause P0102?

The primary reason for a P0102 code is restricted airflow.

This situation is caused by a dirty or clogged air filter. Upon stepping on the gas, the engine needs to ingest a lot of air.

Can you drive with code P0102?

Code P0102 does not pose any serious danger to the driver or the vehicle and there are no drivability issues that may occur. However as the case with all Check Engine Light codes, it should be fixed as soon as possible to prevent any further damage to your vehicle.

What is a low circuit?

OBD Code P0642 - Sensor Reference Voltage "A" Circuit Low

This code means that the powertrain control module (PCM) has detected a low reference voltage signal for a particular sensor that has been given the designation "A".

Can a mass air flow sensor cause transmission problems?

The Mass Airflow Sensor measures airflow into the engine intake assembly and is used to determine engine load. If it fails it can cause automatic transmission problems such as late harsh shifts, early soft shifts, or can result in no shifting at all.

What problems can a bad mass air flow sensor cause?

Mass Air flow Sensor (MAF). As a result, a bad mass air flow sensor causes various driveability problems, including a no-start, stalling, lack of power and poor acceleration. In addition, a faulty mass air flow sensor might cause the Check Engine or Service Engine Soon light to come on.

How much does it cost to replace a mass air flow sensor?

The Average Mass Air Flow Sensor Replacement Cost Ranges from $240 to $330 Depending on if You Go to the Mechanic or DIY. Cost to DIY: $3 to $240, depending on whether you clean the MAF first or replace it. Urgency: Perform this service within a month to avoid vehicle damage.

How important is the mass airflow sensor?

Your Mass Air Flow Sensor (MAF Sensor) is a piece of technology within your engine which tells your car's computer how much air is entering the engine. This is important as it allows your engine to regulate its performance and change the intake of air to keep your engine running in its best condition.
