P0758 (blink 63, U441E) on Toyota Corolla E120: S2 SOLENOID VALVE ELECTRICAL MALFUNCTION
Short answer: P0758 means “S2 SOLENOID VALVE ELECTRICAL MALFUNCTION”. The car’s computer has found a fault in the ECT U441E system. First check: workshop check order (RM821E): INSPECT TRANSMISSION WIRE(S1/S2) -> CHECK WIRE HARNESS AND CONNECTOR(Transmission wire − ECU) -> INSPECT SOLENOID ASSY, TRANSMISSION(S1/S2).
- Code
- P0758 · blink 63
- System
- ECT U441E
- Dashboard light
- CHECK ENGINE (MIL) does NOT light (DTC stored in memory only)
- Applies to
- 4-speed A/T U441E. Not a PK fitment (the PK EPC lists only A246E and U340E). Other-market fitment unverified.
- Confidence
- high (official Toyota RM821E)

Symptoms and when it is set
- (a) Solenoid resistance is 8 W or less (short circuit) when the solenoid is energized. (b) Solenoid resistance is 100 kW or more (open circuit) when the solenoid is not energized. (b) Fail safe function: If either of the solenoid valve circuits develops an open or short, the En noid valve ON and OFF to shift to the gear positions shown in the table ab turns the ST solenoid valve OFF at the same time. If both solenoids malfun not be performed electronically and must be done manually. Manual shifting as shown in the above table must be done (In the case of a ECU stops sending current to the short circuited solenoid).
Likely causes
- Transmission wire; Wire harness; S1/S2 solenoid valve; Engine ECU gine ECU turns the other sole- ove. The Engine ECU also ction, hydraulic control can- short circuit, the Engine
What to check, in order
- Workshop check order (RM821E): INSPECT TRANSMISSION WIRE(S1/S2) -> CHECK WIRE HARNESS AND CONNECTOR(Transmission wire − ECU) -> INSPECT SOLENOID ASSY, TRANSMISSION(S1/S2)

Clearing the code does not fix the fault. If it comes back, the problem is still there. For brakes, airbags and steering, see a trained mechanic.
