Shift Solenoid C Electrical
The transmission's Shift Solenoid C has an electrical problem—either a broken wire, bad connection, or failed solenoid. Think of it like a light switch that won't work; the transmission can't engage the right gear.
The ECM sends a control signal to Shift Solenoid C and monitors the circuit for proper voltage and resistance. It detects opens, shorts, or excessive resistance in the solenoid coil or wiring that prevent normal operation.
| Parameter | Normal Range | Fault Condition |
|---|---|---|
| Solenoid coil resistance | 4–14 ohms (varies by design) | Out of range or infinite (open circuit) |
| Control circuit voltage | 12V when commanded ON | 0V or unstable voltage |
Code P0767 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, P0767 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.
