Title: UA80E (AUTOMATIC TRANSMISSION / TRANSAXLE): AUTOMATIC TRANSAXLE SYSTEM: P28167F; Pressure Control Solenoid "H" Actuator Stuck Off; 2019 - 2020 MY Sienna [08/2018 -        ]

DTC

P28167F

Pressure Control Solenoid "H" Actuator Stuck Off

DESCRIPTION

Based on signals from the transmission revolution sensors (NT and NC), the actual gear is detected.

The ECM compares the actual gear with the shift schedule in the ECM memory to detect mechanical malfunctions of the shift solenoid valves, transmission valve body assembly and automatic transaxle assembly (clutch, brake, gear, etc.).

Actual gear when shift solenoid valve SL5 (without fail-safe control) malfunction occurs:

SL5 stuck ON malfunction:

  1. Engine coolant temperature is 40°C (104°F) or higher, ATF temperature is -10°C (14°F) or higher, and the vehicle is being driven with the shift lever in D (no malfunctions are detected in the shift solenoid valves SL1, SL2, SL3, SL4, SL5, SL6, SLT, SLU and SL, transmission revolution sensors (NT and NC), coolant temperature sensor, oil temperature sensor, knock sensor, electronic throttle or CAN2)
  2. When the ECM commands the transaxle to shift to 1st gear, the engine overruns (neutral status).
  3. Malfunction status continues for 0.5 seconds or more
  4. 2-trip detection logic

SL5 stuck OFF malfunction:

  1. Engine coolant temperature is 40°C (104°F) or higher, ATF temperature is -10°C (14°F) or higher, and the vehicle is being driven with the shift lever in D (no malfunctions are detected in the shift solenoid valves SL1, SL2, SL3, SL4, SL5, SL6, SLT, SLU and SL, transmission revolution sensors (NT and NC), coolant temperature sensor, oil temperature sensor, knock sensor, electronic throttle or CAN2)

MONITOR DESCRIPTION

The ECM commands gear shifts by turning the shift solenoid valves on and off. According to the input shaft revolution (speed) and output shaft revolution (speed), the ECM detects the actual gear (1st, 2nd, 3rd, 4th, 5th, 6th, 7th or 8th gear). When the gear commanded by the ECM and the actual gear are not the same, the ECM illuminates the MIL and stores a DTC.
