Wacky Warning Light

courtesy of Bob, The Auto Answer Man

Dear Bob,
I have a 1995 Plymouth Voyager Van with about 85,000 miles on it. Lately the check engine light has been coming on. I have brought it to the garage and after they charge me $59.00 to run diagnostics, they say they could not find anything.

It seems to occur when I am doing hwy driving between 65 and 70 mph. If I don't go this fast, I will get run over!! But if I get to my destination, turn off the car for awhile, then drive again, it goes away (meaning it does not come back on). Any suggestions?

Any time the light comes on, a code is stored in the onboard computer. A code scanner is used to retrieve these codes and inform a technician where the fault is located. If they are not able to retrieve the codes, then either their equipment is faulty or the computer on your car is faulty. Next time the light comes on, do not shut the car off. Rather, take it directly to the dealer and have them retrieve the codes. Good Luck!
Drive Safely!
