Detecting Condition |
Possible Cause |
| DTC Strategy |
Case 1 |
- Sensor signal cycle check
|
- Poor connector connection
- Sensor contamination by foreign matter (water etc.)
- Blockage or damage to intake system
- Faulty MAFS
|
| Case 2, 3 |
- Sensor diagnostic error signal check
|
| Enable Condition |
Case 1 |
- Engine running condition
- Battery voltage between 11 and 16V
- Time after engine start is more than 0.5s
- Time after Ignition "ON" is more than 0.8s
|
| Case 2 |
- Battery voltage between 11 and 16V
- At engine start-up, engine speed between 928 and 1312 RPM (depends on coolant temperature)
- Pressure rate (intake manifold pressure/barometric pressure) is less than 0.8
|
| Case 3 |
- Battery voltage between 11 and 16V
- At engine start-up, engine speed between 928 and 1312 RPM (depends on coolant temperature)
- Pressure rate (intake manifold pressure/barometric pressure) is more than 0.8
|
| Threshold Value |
Case 1 |
- Sensor signal cycle is short: Sensor signal cycle is less than 85μs and calculated air volume is more than 655kg/h
- Sensor signal cycle is long: Sensor signal cycle is more than 555μs and calculated air volume is less than 7kg/h
|
| Case 2 |
- Air intake area correction value is lower than -90% to -40%, and higher than 40% to 90% (depends on barometric pressure and throttle position)
|
| Case 3 |
- Air intake area correction value is lower than -30% to -20%, and higher than 20% to 30% (depends on barometric pressure)
