P0758 on Toyota
Shift Solenoid "B" Electrical
P0758 on Toyota vehicles indicates shift solenoid "b" electrical. Au7o has documented this code across 2 Toyota models — most commonly on Corolla, RAV4. This powertrain code indicates an electrical fault in the transmission's shift solenoid 'B' circuit. Shift solenoids are electrically controlled valves that route transmission fluid to engage the correct gears (solenoid B is commonly associated with the 2-3 shift). The transmission computer detected the solenoid circuit electrical value (voltage/current) outside the expected range. This can cause harsh or missed shifts, slipping, or the transmission entering limp mode, and should be addressed to avoid further transmission damage. Typical repair costs on Toyota range from $600 to $1,500, depending on the specific model and root cause.
Common Causes of P0758
- •Faulty shift solenoid B
- •Damaged, shorted, or open solenoid wiring/connector
- •Low or contaminated transmission fluid
- •Clogged or worn valve body passages
- •Internal transmission electrical (harness) fault
- •Faulty transmission control module (less common)
P0758 on Toyota by Model
Toyota Corolla(1 issue)
- ECM/PCM Failure Causing Harsh Shifting, No-Start, and MIL Illumination2000-2004
Early-2000s Corolla models are well documented for engine control module failure caused by defective internal circuitry and capacitor/board degradation. Owners report harsh or erratic automatic transmission shifting, stalling, no-start conditions, and check-engine lights because the ECM also controls transmission logic on these cars. Toyota issued a warranty enhancement and service campaign for many affected vehicles, making this one of the best-documented Corolla problems of the period.
Toyota RAV4(1 issue)
- ECM Failure Causing Harsh Shifting, No-Start, or Stalling2001-2003
Early third-party and owner reports, along with Toyota service information, document engine control module failures on 2001-2003 RAV4 models. Failed ECMs can corrupt transmission and engine control signals, leading to harsh or erratic shifting, illuminated warning lights, intermittent no-start, stalling, and poor drivability. This issue is distinct from normal transmission hesitation because the root cause is the ECM hardware itself.

What does P0758 mean on Toyota?▼
P0758 stands for "Shift Solenoid "B" Electrical." This powertrain code indicates an electrical fault in the transmission's shift solenoid 'B' circuit. Shift solenoids are electrically controlled valves that route transmission fluid to engage the correct gears (solenoid B is commonly associated with the 2-3 shift). The transmission computer detected the solenoid circuit electrical value (voltage/current) outside the expected range. This can cause harsh or missed shifts, slipping, or the transmission entering limp mode, and should be addressed to avoid further transmission damage. On Toyota specifically, this code is documented across 2 models.
