1990 Cadillac Deville V8 Front Wheel Drive Automatic

service engine light has come back on after replacing a deverter valve (mechanic said that was the problem) I drove the car home from the repair shop and before I could park it, the service engine came on again and stayed on. The mechanic said the code indicated a deverter valve replacement was needed. I don't know what to think and where to go from here. Any suggestions?

Hi:
Take the car to a nationally recognized parts store and have them scan them scan the computer. Let me know what they find. NOTE: Most stores will scan for free.
