What are some of the common causes of the code?
Causes for this code may include:
- Defective ECT sensor
- Severe vacuum leak
- Open or shorted circuits or connectors
- Bad CKP or CMP sensor

I'd say keep driving the car, watch for any malfunctions or return of the error code/CEL. if none show up you're _probably_ okay.
