| DTC Strategy |
Case 1, 2 |
- Signal Plausibility Monitoring
|
- Poor Connector Connection
- Misadjust crankshaft and camshaft pulley position
|
| Enable Condition |
Case 1 |
- Knock detection function active
- Air mass higher than 0.5g/rev (250mg/tdc)
|
| Case 2 |
- Engine RPM is higher than 2656 RPM
- Engine coolant temperature is higher than 65°C
|
| Threshold Value |
Case 1 |
- Difference between the processed knock sensor signal and its mean does not exceed a threshold (0.08V) and the integral of the processed knock sensor signal does not reach the threshold (3V) for cylinders 2 and 3
|
| Case 2 |
- If the mean processed knock sensor signal of any one cylinder leaves the valid range (lower than 0.1V)
|
