DTC P0076: Notes
DTC P0076 DETECTION & CONDITION POSSIBLE CAUSES
| DTC P0076 |
VDI solenoid valve control circuit low |
| DETECTION CONDITION |
- The PCM monitors the VDI solenoid valve control voltage when the PCM turns the VDI solenoid valve off. If the control voltage is low, the PCM determines that the VDI solenoid valve control circuit voltage is low.
Diagnostic support note
- This is a continuous monitor (Other).
- The MIL does not illuminate.
- PENDING CODE is available if the PCM detects the above malfunction condition during the first drive cycle.
- FREEZE FRAME DATA is available.
- The DTC is stored in the PCM memory.

| POSSIBLE CAUSE |
- VDI solenoid valve malfunction
- Connector or terminal malfunction
- Open circuit in wiring harness between main relay terminal C and VDI solenoid valve terminal A
- Snort to ground in wiring harness between main relay terminal C and VDI solenoid valve terminal A
- Open circuit in wiring harness between VDI solenoid valve terminal B and PCM terminal 1W
- Short to ground in wiring harness between VDI solenoid valve terminal B and PCM terminal 1W
- PCM malfunction
