DTC P0775-7F: Pressure Control Solenoid "B" Actuator Stuck Off [11/2016 - ]: 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 solenoid valves, transmission valve body assembly and automatic transaxle assembly (clutch, brake, gear, etc.).

HINT:

ACTUAL GEAR WHEN SOLENOID (SL2) VALVE MALFUNCTION OCCURS (WITHOUT FAIL-SAFE CONTROL):

ECM commanded gear	1st	2nd	3rd	4th	5th	6th	7th	8th
Actual gear during SL2 stuck ON malfunction	5th	5th	3rd to 5th	4th to 5th	5th	6th	7th	8th
Actual gear during SL2 stuck OFF malfunction	1st	2nd	3rd	4th	N*	N*	N*	N*

Pressure Control Solenoid "B" Actuator Stuck Off

1. Diagnosis Condition, 2. Malfunction Status, 3. Malfunction Time, 4. Other
SL2 stuck ON malfunction:

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 solenoid (SL1, SL2, SL3, SL4, SL5 and SL6) valves, transmission revolution sensors (NT and NC), coolant temperature sensor, oil temperature sensor, knock sensor, electronic throttle or CAN2)
When the ECM commands the transaxle to shift to 1st, 2nd, 3rd or 4th gear, the actual gear changes to 5th gear.
Malfunction status continues for 0.8 seconds or more
2-trip detection logic

SL2 stuck OFF malfunction:

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 solenoid (SL1, SL2, SL3, SL4, SL5 and SL6) valves, transmission revolution sensors (NT and NC), coolant temperature sensor, oil temperature sensor, knock sensor, electronic throttle or CAN2)
When the ECM commands the transaxle to shift to 5th, 6th, 7th or 8th gear, the engine overruns (neutral status).
Malfunction status continues for 0.5 seconds or more
