Cadillac Repair Questions? Ask a Mechanic for Answers ASAP
What is the sensor for?What light are you talking about?
There is no such thing as a "sensor light". Please explain exactly what problem you're having and what you are trying to do. Thanks.
The common problem is the torque converter clutch solenoid which is a big job, usually just living with the light is best option if vehicle runs good. Otherwise it is about a 8 hour job to replace the solenoid and a $200 part. You can press/hold the INFO OFF/ON and INFO UP buttons to check codes. Let me know what codes your getting and I can verify problem. Thanks.
In that case you will need to fix problem for it to pass smog. Let me know what diagnostic code your getting and I'll verify repair that needs to be made. Let me know, thanks.
