Description
The ecm uses signals from the output shaft speed sensor and input speed sensor to detect the actual gear position (1st, 2nd, 3rd or o/d gear).
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, 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.
Monitor strategy
Typical enabling conditions
Typical malfunction thresholds
Either of the following conditions is met: off malfunction or on malfunction
2 Detections are necessary per driving cycle: 1st detection: temporary flag on
2Nd detection: pending fault code on
Inspection procedure
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.
Hint:
While driving, the shift position can be forcibly changed with the tester.
Comparing the shift position commanded by the active test with the actual shift position enables you to confirm the problem (see page ax-31).
Hint:
Result
Hint:
If any other codes besides p0776 are output, perform troubleshooting for those dtcs first.
Standard resistance: 5.0 To 5.6 Ùat 20°c (68°f)
Ok: valve moves and makes operating noise.
Ok: there are no foreign objects on each valve.
Ok: the torque converter clutch operates normally.
Repair or replace automatic transaxle assembly
If your vehicle overheats
The following may indicate that your vehicle is overheating.
The high engine coolant temperature warning light Comes
on or a loss of engine power is experienced. (For example, the
vehicle speed does not increase.)
Steam comes out from under the hood.
