Probable Causes to Investigate
Our diagnostic process examines these possibilities:
- MAF sensor contamination (40% likelihood) - Commercial conditions
- Intake system leak (28% likelihood) - Vacuum leak
- Air filter issues (17% likelihood) - Maintenance interval
- MAF sensor failure (10% likelihood) - Electronic issue
- ECU calibration (5% likelihood) - Software update
Diagnostic Procedure
Begin with visual inspection of the air intake path. Commercial vans need regular inspection. Verify air filter condition. Monitor MAF readings with a scan tool.
Cost Analysis
- MAF sensor cleaning: $15-$35 (DIY)
- Air filter replacement: $30-$60
- Intake repair: $80-$230
- MAF sensor replacement: $140-$360
Commercial Vehicle Service
