What Does P2280 Mean?
The PCM has detected an air flow restriction or unmetered air leak between the air filter housing and the Mass Air Flow (MAF) sensor. This disrupts the air flow measurement and affects fuel delivery calculations.
Common Causes
35%
Clogged or severely restricted air filter
30%
Torn or disconnected air intake duct between filter and MAF
20%
Collapsed or damaged intake snorkel or housing
10%
Foreign object or debris blocking air flow path
5%
Cracked air filter housing allowing unmetered air
Diagnostic Steps
1
Step 1: Perform visual inspection of air filter for excessive dirt/restriction and proper fitment
2
Step 2: Inspect all intake ducting between air filter and MAF sensor for cracks, tears, or disconnections
3
Step 3: Check air filter housing for cracks, damage, or improper sealing
4
Step 4: Verify proper installation of air filter and housing assembly
5
Step 5: Clear codes, test drive, and verify repair
Estimated Repair Cost
$30 - $200
Parts + labor, varies by vehicle and location
The PCM has detected an air flow restriction or unmetered air leak between the air filter housing and the Mass Air Flow (MAF) sensor. This disrupts the air flow measurement and affects fuel delivery calculations.
The most common cause of P2280 (Air Flow Restriction/Air Leak Between Air Filter and MAF) is: Clogged or severely restricted air filter
Typical repair costs for P2280 range from $30 to $200, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Generally safe to drive but may experience reduced performance, rough idle, and poor fuel economy. Extended operation may damage MAF sensor.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P2280 to identify the root cause.
