• Check Engine Light on
• Poor fuel economy
• Rough idling
• Faulty MAF sensor
• Dirty or clogged air filter
• Air leaks in the intake system
MAF Sensor: Mass Air Flow Sensor, a device that measures the amount of air entering the engine.
ECM: Engine Control Module, the computer that controls engine functions.

Mass or Volume Air Flow Circuit Range/Performance Problem (Bank 2)
This code means that the car's computer is having trouble measuring how much air is going into the engine on one side of the engine. It's like if you were trying to bake a cake but couldn't figure out how much flour you were putting in.
The P1116 code indicates a problem with the mass air flow sensor circuit on Bank 2 of the engine, which is responsible for measuring the amount of air entering the engine to ensure proper air-fuel mixture.
The Mass Air Flow (MAF) sensor measures the amount of air entering the engine. The engine control module (ECM) uses this information to calculate the proper amount of fuel to inject. A P1116 code is set when the ECM detects a range or performance issue with the MAF sensor circuit on Bank 2, meaning the sensor's signal is outside the expected range.
• Use an OBD-II scanner to verify the code.
• Inspect the MAF sensor and its wiring for damage.
• Check for air leaks in the intake system.
• Clean or replace the MAF sensor.
• Replace the air filter if it's dirty.
• Repair any air leaks in the intake system.
• OBD-II scanner
• Multimeter
• Screwdriver set

Moderate
• Toyota Camry
• Honda Accord
• Ford F-150
• Regularly replace the air filter.
• Keep the MAF sensor clean.
• Perform regular maintenance checks.
Sensor Issue
• Address this issue promptly to avoid further engine problems.
• Consider consulting a professional mechanic if unsure about repairs.
Check with your vehicle manufacturer for warranty coverage on emission-related components.
This code has been commonly associated with MAF sensor issues in various vehicle models, often due to sensor contamination or wiring issues.
Moderate – It should be addressed soon to prevent potential engine performance issues.
Driving with a malfunctioning MAF sensor can lead to increased emissions and may not comply with local emissions regulations.
• Engine at operating temperature
• Vehicle at idle
The MAF sensor is typically located between the air filter box and the throttle body in the engine bay.
Q: What happens if I ignore this code?
A: Ignoring this code can lead to poor engine performance and increased fuel consumption.
Q: Can I drive my car with this code?
A: While the car may still be drivable, it's best to address the issue to avoid further damage.
