DTC P06DB-00: (PCM, VIN M) DETECTION CONDITION AND POSSIBLE CAUSE
| DTC P06DB-00: |
Engine oil solenoid valve circuit low input |
| DETECTION CONDITION |
- If the PCM detects that the engine oil solenoid valve control voltage at the PCM terminal 1CK is specified value or less for 2 s with the following condition met, the PCM determines that the engine oil solenoid valve circuit voltage is low.
MONITORING CONDITIONS
- Battery voltage: 8 V or more
- 0.5 s have elapsed after the ignition was switched ON (engine off or on)
- Engine oil solenoid valve control duty value: 94% or less Diagnostic support note
- This is a continuous monitor (CCM).
- The check engine light illuminates if the PCM detects the above malfunction condition during the first drive cycle.
- FREEZE FRAME DATA/Snapshot data is available.
- DTC is not stored in the PCM memory.
|
| FAIL-SAFE FUNCTION |
- Restricts the upper limit of the engine speed.
- Restricts engine load.
|
| POSSIBLE CAUSE |
- Engine oil solenoid valve connector or terminals malfunction
- Short to ground or open circuit in engine oil solenoid valve power supply circuit
- Short to ground in wiring harness between ENGINE4 15 A fuse and engine oil solenoid valve terminal A
- ENGINE4 15 A fuse malfunction
- Open circuit in wiring harness between main relay terminal C and engine oil solenoid valve terminal A
- PCM connector or terminals malfunction
- Short to ground in wiring harness between engine oil solenoid valve terminal B and PCM terminal 1CK
- Open circuit in wiring harness between engine oil solenoid valve terminal B and PCM terminal 1CK
- Engine oil solenoid valve malfunction
- PCM malfunction
