P0776
DTC P0776 Pressure Control Solenoid "B" Performance (Shift Solenoid Valve SL2)DESCRIPTION
The ECM uses signals from the output shaft speed sensor and input speed sensor to detect the actual gear position (1st, 2nd, 3rd, 4th or 5th gear).
P0776:
Then the ECM compares the actual gear with the shift schedule in the ECM memory to detect mechanical problems of the shift solenoid valves, valve body or automatic transaxle (clutch, brake or gear, etc.).
MONITOR DESCRIPTION
This DTC indicates a stuck ON malfunction or stuck OFF malfunction of the shift solenoid valve SL2.
The ECM commands gear shifts by turning the shift solenoid valves ON/OFF. When the gear position commanded by the ECM and the actual gear position are not the same, the ECM illuminates the MIL and stores the DTC.

TYPICAL ENABLING CONDITIONS
TYPICAL MALFUNCTION THRESHOLDS
Either of these conditions are met:
OFF malfunction or ON malfunction
2 detections are necessary per driving cycle:
1st detection; temporary flag ON
2nd detection; pending fault code ON
HINT: Performing the intelligent tester's ACTIVE TEST allows relay, VSV, actuator and other items to be operated without removing any parts. Performing the ACTIVE TEST early in troubleshooting is one way to save time.
The DATA LIST can be displayed during the ACTIVE TEST.
1. Warm up the engine.
2. Turn the ignition switch OFF.
3. Connect the intelligent tester to the DLC3.
4. Turn the ignition switch ON.
5. Turn the intelligent tester ON.
6. Enter these menus: DIAGNOSIS / ENHANCED OBD II / ACTIVE TEST.
7. Follow the instructions on the tester and read the ACTIVE TEST.
HINT: While driving, the shift position can be forcibly changed with the intelligent tester. Comparing the shift position commanded by the ACTIVE TEST with the actual shift position enables you to confirm the problem.
HINT:
- This test can be conducted when the vehicle speed is 50 km/h (31 mph) or less.
- The shift position commanded by the ECM is shown in the DATA LIST (shift status) display on the intelligent tester.
