Over 2 years ago the SERVICE ENGINE SOON light went on. Took it the mechanic got a new 02 sensor. Light was still on, he didn't know what it was. I didn't do anything about it for two years. Car runs excellent. Went for a recall earlier this year Nissan said that it is the oxygen sensor. Didn't get it fixed. Went for inspection in May. Failed. Reason p0420. Went back to NISSAN, they said they couldn't fix it cause they are not authorized by the state to do emission work once the car failed inspection. I later went to 3 mechanics, this is what they told me. It needs a new cat converter. It needs an 02 sensor. It need a new computer. Question number one: Is the computer in a car called ECU? Is that what they mean when they talk about ECU? the computer of the car? Does anyone know anything about this. Has anyone had the same problem?
Thank you.
