Conditions For Setting DTC

Engine is running.
No Throttle Position (TP) sensor and Manifold Absolute Pressure (MAP) sensor DTCs are set.
No MAF frequency DTCs are set.
System voltage is between 11.5 and 16.0 volts.
The time since barometric pressure was update is 3 minutes.
Engine speed is between 650 and 4000 RPM.
Engine coolant temperature is above 86°F (30°C).
No change is A/C clutch or TCC status.
Throttle position is steady, changing less than 5 percent.
MAP value is steady, changing less than 5 kPa.
EGR flow rate is steady, changing less than 5 percent.
Idle air flow rate is steady, changing less than 5 percent.
The absolute value of the difference for actual MAF value and expected MAF value is more than high threshold, or less than low threshold value for 5 seconds
