Drive with caution — fix soon.
This code means the control module detected a low voltage or low signal in the shift/timing solenoid circuit. It's typically caused by damaged or shorted wiring, corroded connectors, or a failing solenoid, and sometimes a control module fault. Repairs usually involve inspecting and repairing the circuit, cleaning connectors, or replacing the solenoid.

Varies by vehicle and root cause.
Often yes in the short term, especially if the car still shifts normally. But because it's an electrical fault, it can cause erratic shifting or limp mode, so get it diagnosed soon rather than letting it linger.
It's frequently on the lower side. Repairing wiring or cleaning connectors may cost relatively little, while replacing the solenoid can run a few hundred dollars depending on access and labor.
It's usually moderate. The car often drives, but an unaddressed circuit fault can lead to shifting problems or limp mode, so it's worth fixing before it gets worse.
It means the voltage or signal in the solenoid circuit is lower than expected, often due to a short to ground or wiring damage. The fix usually involves checking the wiring and connectors before replacing parts.
