P2808

DTC P2808 Pressure Control Solenoid "G" Performance or Stuck OFF (Shift Solenoid Valve SL4)

DESCRIPTION
The TCM uses the vehicle speed signal to determine the actual gear position (1st, 2nd, 3rd, 4th, 5th or 6th gear).
Then the TCM compares the actual gear with the shift schedule in the TCM memory to detect shift solenoid valves and valve body mechanical problems.





MONITOR DESCRIPTION
The TCM commands gear shifts by turning the shift solenoid valves on or off. According to the input shaft revolution, intermediate (counter) shaft revolution and output shaft revolution, the TCM detects the actual gear position (1st, 2nd, 3rd, 4th or 5th gear position). When the gear position commanded by the TCM and the actual gear position are not the same, the TCM illuminates the MIL and stores the DTC.
