DTC P0202:00 (L3 WITH TC) DETECTION CONDITION & POSSIBLE CAUSES
| DTC P0202:00 |
Injector circuit/open cylinder No. 2 |
| DETECTION CONDITION |
- If the fuel injection verification signal is not input at 255 times
continuously even though the PCM drives the fuel injector No. 2, the PCM determines that there is an open circuit in the fuel injector No. 2 control circuit.
MONITORING CONDITIONS
- Engine speed: 4, 000 rpm or less
- Battery voltage: 10.03 V or more
- Fuel injection control: except during fuel cut
Diagnostic support note
- This is a continuous monitor (CCM).
- The MIL illuminates if the PCM detects the above malfunction condition during the first drive cycle.
- FREEZE FRAME DATA (Mode 2)/Snapshot data is available.
- The DTC is stored in the PCM memory.
