P0753 (blink 62) on Toyota Corolla E120: S1 SOLENOIN VALVE ELECTRICAL MALFUNCTIN

Short answer: P0753 means “S1 SOLENOIN VALVE ELECTRICAL MALFUNCTIN”. The car’s computer has found a fault in the ECT A245E/A246E system and turns on the Malfunction indicator lamp (Check Engine). First check: 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.

Code: P0753 · blink 62

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

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.
