What is the problem with the Subaru air flow sensor?

Problems with Subaru Air Flow Sensor
The Subaru mass air flow sensor (MAF sensor) can experience various issues that affect the performance of the vehicle. Some common problems associated with Subaru air flow sensors include:
1. Performance Issues: A faulty mass air flow sensor can have a devastating effect on the engine, leading to performance issues.
2. Symptoms of a Defective MAF Sensor: Common symptoms of a defective MAF sensor on a Subaru include:
– Check engine light staying on
– Rough or shaky engine operation
– Engine misfire detected
– Poor fuel economy
– Cruise control light coming on
– Engine hesitating under load or at idle
– Engine struggling to start
– Rough idle
– Triggering of fault codes such as P0101, P0171, P0174, or P0102.
3. Error Codes: Error codes related to the mass or volume air flow circuit high input, such as PO103, can indicate issues with the air flow sensor.
4. Effect on Transmission: A problem with the air flow sensor could also alter the shifting pattern of the automatic transmission.
5. Cleaning and Maintenance: Regular cleaning of the mass airflow sensor is recommended to prevent issues. Cleaning it when changing or cleaning the air filter can help maintain its proper functioning.
6. Replacement Cost: The cost of replacing a faulty mass air flow sensor can vary, with some garages quoting around $500 for the replacement part and labor.
In summary, the Subaru mass air flow sensor is a crucial component that, when faulty, can lead to a range of performance issues and trigger various error codes. Regular maintenance and prompt replacement when necessary are essential for optimal vehicle performance.

How much does it cost to fix a faulty air flow sensor?

The average cost for a Mass Airflow Sensor Replacement is between $239 and $346. Labor costs are estimated between $37 and $46 while parts are priced between $202 and $300.

How do you clean a Subaru mass air flow sensor?

So you want to wear some gloves. And you don’t want to touch. The spray nozzle to the wires. Themselves. You know just kind of get everything. Good. Let it dry in between sprays a little. Bit.

What happens when air flow sensor goes bad?

A bad MAF sensor can cause your vehicle to experience poor drivability issues such as engine stalling, jerking or hesitation during acceleration. This could happen while speeding up on the highway on-ramp or cruising down a city street. These issues can create dangerous situations causing accidents and injury.

Will car run with mass air flow sensor unplugged?

When you unplug the MAF, the computer goes to a default value stored in your memory. Your fuel economy will probably suffer a little bit, but no big issues. You’re OK for a week or two, but replace the MAF with a proper TDI unit. Long term effects is that the car does not operate to it’s full potential.

Is it better to clean a mass air flow sensor or replace it?

Although cleaning a contaminated MAF may seem to bring the performance back, it rarely brings it to 100 percent operation and accuracy. There are many instances where the internal circuitry is damaged or shorted. In these cases, the sensor needs to be replaced.

Can I drive my car with a bad air flow sensor?

Although in some cases, you may technically be able to continue driving with a bad MAF sensor, you should address the issue as soon as possible. A faulty MAF can damage other parts of your vehicle, such as the catalytic converter. What’s more, some cars won’t even run when the MAF fails.

What are the problems related with the mass air flow sensor?

The engine won’t receive the proper airflow if you have a faulty mass airflow sensor. This, in turn, can lead to your car running roughly or the engine misfiring. That happens because the imbalance means that your powertrain control module can’t determine how much fuel your engine needs to run.

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

The average cost for a Mass Airflow Sensor Replacement is between $239 and $346. Labor costs are estimated between $37 and $46 while parts are priced between $202 and $300.

How often do mass air flow sensors fail?

A mass air flow typically last between 80,000 miles to 150,000 miles. Proper maintenance of the mass air flow and cleaning it will help prolong its life. However, there are a few vehicle symptoms that will tell you when it is time to replace the air flow sensor. The first symptom is hard starting.

Can you clean a mass air flow sensor without removing it?

Removing the sensor is recommended for best results, but it’s not necessary. Apply 10 to 15 short bursts of CRC MAF cleaner to the hot wire or hot plate. Keep the end of the straw 100 to 120 mm away from the hot wire while spraying.
