pull the carpet up by the firewall on the passenger side to expose the ecu. There is a little light on the ecu, it will blink. Long blinks = 10 and short blinks = 1. So, if there is 4 long blinks followed by 1 short blink that is 41. Check what code 41 means in a manual or online.
I payed $60 for an o2 sensor for my eg.
Does your car idle kinda rough? Notice less gas mileage?

a dead o2 sensor doesn't cause the engine light to come on on older cars
