Drive with caution — fix soon.
This code means the control module detected a high voltage or open circuit condition in the shift/timing solenoid circuit. It's commonly caused by an open or broken wire, corroded or disconnected connectors, or a failed solenoid, and sometimes a control module fault. Repairs usually involve testing and repairing the wiring, cleaning connections, or replacing the solenoid.
$100 – $900
Varies by vehicle and root cause.
Often yes for the short term, particularly if the car still shifts properly. Since it's an electrical fault, though, it can lead to erratic shifting or limp mode, so it's best to have it diagnosed soon.
It's often relatively affordable. Repairing an open wire or corroded connector may cost little, while replacing the solenoid can run a few hundred dollars depending on labor and access.
It's usually moderate. The vehicle often still drives, but leaving an electrical fault unaddressed can cause shifting problems or limp mode, so it's worth repairing promptly.
It means the circuit voltage is higher than expected or the circuit is open, often from a broken wire or loose connector. Diagnosis usually starts by checking the wiring and connections before replacing the solenoid.
