DTC P2807-12: Pressure Control Solenoid "G" Circuit Short to Battery [12/2019 - 10/2022]: Description
Changing gears is performed by the ECM turning the solenoid (SL1, SL2, SL3, SL4, SL5 and SL6) valves on and off.
If an open or short occurs in any of the solenoid valve circuits, the ECM controls the remaining normal solenoid valves to allow the vehicle to be driven. If all of the solenoid valves are malfunctioning, only the mechanical fluid pressure circuit will function and some manual operation will be possible. If an open or short occurs in a solenoid valve circuit, the ECM cuts power to the malfunctioning solenoid valve.
HINT:
The following table shows normal operation of the solenoid (SL4) valve when the shift lever is in D.
SOLENOID VALVE OPERATION:
| Gear | 1st | 2nd | 3rd | 4th | 5th | 6th | 7th | 8th |
|---|---|---|---|---|---|---|---|---|
| Solenoid (SL4) Valve | OFF | OFF | OFF | ON | OFF | ON | OFF | OFF |
| DTC No. | Detection Item | DTC Detection Condition | Trouble Area | MIL | Memory | Note |
|---|---|---|---|---|---|---|
| P2807-12 | Pressure Control Solenoid "G" Circuit Short to Battery | While the vehicle is being driven so that gear changes occur, a short to +B is detected in the solenoid (SL4) valve circuit for 1 second (1-trip detection logic). |
