| DTC Strategy |
Case1 |
- Monitor the MAP sensor's signal
|
- Connecting condition
- Open or short to ground in power circuit
- Open or short to ground in signal circuit
- Faulty TPS
- Faulty MAPS
- Faulty PCM
|
| Case2 |
- The MAP reading is compared to expected MAP high and low limits based on engine speed & Throttle Position
|
| Case3 |
- This code detects a erratic signal change of the MAP
|
| Enable Conditions |
Case1 |
- No Disabling Fault Present
- Shutdown time > 20 minutes
- Engine running
|
| Case2 |
- Engine Coolant Temperature ≥ 60°C (Fully Warmed up state)
- 600 rpm < Engine Speed < 3000 rpm
|
| Case3 |
- Engine running
- l ΔAPS l < 5%
- Engine Speed > 800 rpm
|
| Threshold value |
Case1 |
- The difference between the signal at key-on and the signal at engine start < 0.5 kPa
|
| Case2 |
- Power Test
- Altitude compensated MAP < Calculated min. MAP data
- Altitude compensated MAP > Calculated max. MAP data
- Deceleration Test
- Altitude compensated MAP < Calculated MAP data
|
| Case3 |
- MAP_stable -MAP_current >10 %
|
| Diagnosis Time |
Case1 |
- For 3 seconds out of 5 seconds
|
| Case2 |
- Continuous (within 5 min.)
|
| Case3 |
|
| MIL On Condition |
