DTC P2817 Pressure Control Solenoid "H" Performance or Stuck OFF (Shift Solenoid Valve SL5)

DESCRIPTION
Based on signals from the transmission revolution sensor (NT and NC), gear position is detected. If the detected gear position is different than the commanded gear position, the TCM detects related mechanical problems in the shift solenoid valve, valve body and automatic transmission.

HINT: Gear shift position when a problem occurs in shift solenoid valve SL5:





*: Neutral

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, 5th, 6th, 7th or 8th gear position). When the gear position commanded by the TCM and the actual gear position are not the same, the TCM illuminates the MIL.
