Question about 1996 Cadillac Eldorado
After runnig my car through an emissions check for the state it threw a code complaining about bank 1 sensor 1. What could this be and where is sensor 1 located if yu are standing in front of the car?
Tightened the gas cap. Emisions testing left it slightly loose setting off the sensor warnings. Even if it doesn't "look" like it is ose take it off and put it back on tight. If the warnings are still flashing then it prob is the sensor. Caddy's are very touchy about their gas caps!
