P0758 · blink 63 – S2 SOLENOID VALVE ELECTRICAL MALFUNCTION
- 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.
- Check-engine blink code
- 63
- Description
- S2 SOLENOID VALVE ELECTRICAL MALFUNCTION
- Detection / symptoms
- Detection: (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).
- Possible 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
- Workshop check order (RM821E): INSPECT TRANSMISSION WIRE(S1/S2) -> CHECK WIRE HARNESS AND CONNECTOR(Transmission wire − ECU) -> INSPECT SOLENOID ASSY, TRANSMISSION(S1/S2)
- Confidence
- high (official Toyota RM821E)
