What can cause a MAF sensor to fail?
The sensor element could get contaminated or damaged. Sometimes, an improperly-installed or ripped air filter can cause the MAF sensor to fail sooner. Over-soaking a washable air filter with oil can also cause troubles with the air flow sensor.
How much does it cost to replace mass air flow sensor?
The mass air flow sensor must be cleaned and the air filter must be reinstalled correctly or replaced. If the air flow sensor is bad, it needs to be replaced. It’s a fairly simple job. The part costs from $89 to $380.
