MAF: Mass Air Flow
Sensor Drift: Gradual change in sensor readings over time

Mass or Volume Air Flow Too High due to Sensor Drift (Bank 2)
The car's computer thinks too much air is going into the engine on one side because a sensor is not working right.
The Mass Air Flow (MAF) sensor measures the amount of air entering the engine. If it reads too high, it can cause the engine to run poorly.
The P3267 code indicates that the MAF sensor on Bank 2 is reporting an unusually high air flow rate. This could be due to sensor drift, where the sensor readings gradually become inaccurate over time.
• Use an OBD-II scanner to confirm the code.
• Inspect the MAF sensor and wiring for damage.
• Check for air leaks in the intake system.
• Replace the faulty MAF sensor.
• Repair or replace damaged wiring.
• Fix any air leaks in the intake system.
• OBD-II scanner
• Multimeter
• Basic hand tools

Moderate
• Toyota Camry
• Honda Accord
• Ford F-150
• Regularly clean the MAF sensor.
• Ensure air filters are replaced on schedule.
• Inspect intake system for leaks periodically.
Sensor Issue
• Do not ignore the Check Engine Light.
• Consult a professional mechanic if unsure.
• Regular maintenance can prevent this issue.
Check with your vehicle's manufacturer for specific warranty coverage on emissions-related components.
This code has been more common in vehicles with aging MAF sensors or those exposed to harsh environmental conditions.
Moderate – It affects engine performance and fuel efficiency but is not an immediate threat.
Driving with a faulty sensor can lead to increased emissions, which may not comply with local environmental regulations.
• Engine at normal operating temperature
• Vehicle at idle
The MAF sensor is typically located between the air filter box and the throttle body.
Q: Can I drive with a P3267 code?
A: It's possible, but not recommended as it can affect engine performance and fuel efficiency.
Q: How often should the MAF sensor be cleaned?
A: It's a good practice to clean the MAF sensor every 15,000 to 30,000 miles or as part of routine maintenance.
