| DTC Strategy |
|
- Poor Connector Connection
- Power circuit is open/short to ground
- Signal circuit is open/short to ground
- MAPS
- TPS
- ECM
|
| Case 1 |
Enable Condition |
- Engine speed is higher than 608RPM to 960RPM when engine "ON"
- Pressure ratio (Intake manifold pressure/Barometric pressure) is below 0.8
- Battery voltage higher than 11V and lower than 16V
|
| Threshold Value |
- Calibration value of air intake area model is lower than -90% to -40% or higher than 40% to 99.5%
|
| Diagnostic Time |
|
| MIL ON Condition |
|
| Case 2 |
Enable Condition |
- Engine speed is higher than 608RPM to 960RPM when engine "ON"
- Pressure ratio (Intake manifold pressure/Barometric pressure) is below 0.8
- Battery voltage higher than 11V and lower than 16V
|
| Threshold Value |
- The atmospheric pressure correction value for the amount of air model is lower than -14.5% to -20% higher than 14% to 20% (The reference value is a function of the atmospheric pressure)
|
| Diagnostic Time |
|
| MIL ON Condition |
|
| Case 3 |
Enable Condition |
- Time of engine "OFF" is over 2.6s
- Engine speed is below 32RPM
- The measured value from baro sensor is higher than 400 hPa and lower than 1150 hPa
- MAPS voltage is higher than 0.2V and lower than 4.8V
- TPS voltage is higher than 0.2V and lower than 4.8V
|
| Threshold Value |
- Intake air pressure (MAP) is out of the reference range when engine "OFF"
|
| Diagnostic Time |
|
| MIL ON Condition |
|
| Case 4 |
Enable Conditions |
- Engine speed is higher than 608RPM to 960RPM
|
| Threshold Value |
- Intake air pressure (MAP) is out of the reference range when engine "ON"
|
| Diagnostic Time |
|
| MIL ON Condition |
