Shift Solenoid B Stuck On
Your transmission's Shift Solenoid B is electrically stuck in the ON position, preventing it from turning off when needed. Think of it like a light switch that won't flip off—the solenoid stays energized and disrupts normal gear shifting.
The ECM monitors solenoid B's electrical resistance and response time during shift commands. It detects when the solenoid fails to de-energize after the command signal ends, indicating the valve is mechanically or electrically stuck open.
| Parameter | Normal Range | Fault Condition |
|---|---|---|
| Solenoid De-energize Time | 50-200ms response after signal removal | No de-energization detected or exceeds 500ms |
| Solenoid Coil Resistance | 5-15 ohms | Short circuit (<2 ohms) or open circuit (>20 ohms) |
Code P0761 is a moderate fault. You can generally drive to a workshop, but avoid long trips or high-load driving (motorway, uphill towing) until it is diagnosed. If the code keeps returning after clearing, or if you notice the symptoms listed above worsening, do not delay professional diagnosis. Many moderate codes have multiple possible root causes — a mechanic with live OBD data can identify the exact fault more efficiently than part-by-part trial and error.
Once the fault is repaired, P0761 can be cleared using any OBD-II scanner. Connect the scanner, navigate to "Clear Codes" or "Erase DTCs," and confirm. The check engine light turns off immediately.
The code will return if the root cause was not actually fixed. The ECM re-detects the fault within 1–3 drive cycles and sets the code again.
