Have a Car Question? Ask a Mechanic Online.
I had the car in to two different autoparts stores this last Sunday. Used their scanners to hook into the computer port to check the codes while the car was running and the Check TOD light was flashing. No codes came up or were detected at either place.
If I take it in to a mechanic and have the sensors removed and tested, it'll cost me a couple of hundred dollars just for the diagnosis. If it is indeed failing sensors or a bad connection, is that something I can take care of myself? I know where the sensors are, don't know what it'll take to remove and replace them though. Can you advise on where I might find new replacement sensors and what the cost for a replacement part might be? If I chose to keep driving the vehicle as is, what is the risk?
