What exactly is it? Please report this advertisement. The Mass Air Flow (MAF) sensor detects the amount of air that is introduced into the engine. P0104 is set when there is uneven or irregular voltage output to the ECM, PCM, or ECU depending on the kind of vehicle (see your owner’s handbook for further information on your vehicle’s specific model).

How do you fix a mass air flow sensor code?
How to Correct the Code P0101 Error
- Step 1: Repair any damage to the wiring. Identify any broken wiring or connectors that were discovered during the diagnostic procedure and make any required repairs.
- Repair or replace the damaged intake ducting in Step 2.
- The next step is to thoroughly clean the MAF sensor.
- Vacuum Leaks Should Be Repaired in Step 4.
- MAF Sensor should be replaced in Step 5.
What can cause a mass airflow sensor code?
Oil from an oil-soaked aftermarket air filter can contaminate the MAF sensor element in cars with an oil-soaked aftermarket air filter, resulting in the code P0101 or other MAF-related problems. It is possible that a filthy throttle body or vacuum leaks in the PCV system are to blame for the code P0101 in some Volvo vehicles (e.g. vacuum line to the oil separator).
What does diagnostic code P0104 mean?
P0104 is described as a Mass or Volume Air Flow Circuit Intermittent in the OBD-II code system. It is the Mass Airflow Sensor (MAF) that detects the amount of air entering the engine, and it is the Engine Control Module (ECM) that utilizes this information to decide the right amount of fuel to use and when to ignite the engine.
What are the signs of a failing mass air flow sensor?
- Symptoms of a Faulty Mass Air Flow Sensor The Check Engine Light is illuminated. A faulty MAF sensor can result in the illumination of the check engine light, which is one of the warning lights on the dashboard of a vehicle.
- Problems with acceleration.
- Idling in a haphazard manner.
- Unacceptably low fuel efficiency.
- Exhaust smoke that is dark in color.
- A squeezing or hesitating sensation.
- Starting out is difficult
Can a dirty air filter cause MAF code?
Symptoms of a clogged air filter It is true that the air filter, which is part of the engine’s air intake system, is the MAF sensor’s first line of defense, but an air filter that is blocked, of poor quality, or unclean can actually be the source of MAF sensor damage if any contamination gets past it.
Can you drive with a P0101 code?
Code P0101 does not pose any hazard to the driver and will not prohibit the vehicle from operating normally. It will, however, result in an increase in fuel consumption as well as harsh operation. Internal engine failure can occur as a result of prolonged driving.
How much does a MAF sensor cost?
Many mass air flow sensors will cost between $100 and $150, but others may cost as much as $400 or more — particularly in higher-end German models. Because most of these sensors are located on the air induction system, installation will not be prohibitively expensive, often ranging between $20 and $50.
How do I fix code P1101?
What fixes may be performed to resolve the P1101 error code?
- Replace or replace any broken, damaged, or loose wire, connections, or components that are found inside the MAF sensor harness, as necessary.
- If the air filter is clogged, it should be cleaned or replaced.
- Cleaning the MAF sensor with a specialist cleaner is recommended.
- Repair any leaks that may have occurred within the vacuum system.
How long does it take for mass air flow sensor to reset?
What is the average time it takes for the mass air flow sensor to reset? You will be able to reset the ECU after reconnecting the battery for ten minutes. It’s possible that the symptoms were caused by anything other than the damaged air flow sensor (which was the cause of the problem).
How do you clean a mass air flow sensor?
Spray 10-15 spurts of CRC MAF Sensor Cleaner onto the sensor’s surface in a circular motion. Spray all surfaces of the sensor and housing, including the connections, with the solution. Don’t forget to saturate the terminals with spray. Reinstall the sensor into the vehicle and wait a few minutes for the chemicals to drain before turning on the engine once more.
How do I know if my MAF sensor is dirty?
There are seven signs that your mass airflow sensor is dirty or failing.
- Exhaust pipe in black. One symptom that your vehicle’s MAF is failing is the presence of black exhaust from excessive fuel.
- Engine should be checked. A defective mass airflow sensor is one of the most common reasons for the check engine light to illuminate.
- Starts off slowly.
- Gasoline economy is poor.
- Idleness is a rough state of affairs.
- Having difficulty accelerating
Can a mass air flow sensor cause transmission problems?
The Mass Airflow Sensor detects the amount of air that enters the engine’s intake component, and it is used to assess the amount of power the engine is producing. This failure can result in automatic transmission issues such as late hard shifts, early soft shifts, and perhaps no shifting at all if the sensor is not replaced.
Why would a car run better with the mass air flow sensor unplugged?
After disconnecting it, the car appears to operate more smoothly than it did before the MAF sensor was removed. What is the reason behind this? If the automobile performs better when the MAF sensor is disconnected, this indicates that the sensor is producing false readings and has to be cleaned or replaced as a result of the malfunction.
