| DTC Strategy |
- Pumping current circuit (VIP) open
|
- Poor connector connection
- Open to virtual ground circuit (Vg)
- Upstream HO2S
|
| Enable Conditions |
- Battery voltage is between 9 and 16V
- The upstream HO2S heating duration longer than 70s (after the heating point ends)
|
| Threshold Value |
- Virtual ground (Vg) circuit resistance is higher than 4644Ω or the voltage between Vip and virtual ground (Vg) is higher than 1.2V and the voltage between reference voltage circuit (Vn) and Vg is less than 1.2V
