2001 I30 Question

[IrvW]

SES light came on. I took it to AutoZone and they said it was the O2 sensor, high voltage. They reset it and the light was off for about 300 miles, then it came on again. Later on I took a long trip and the low fuel light came on, as my tank got very low. I filled up the tank and and when I stared the car the SES light was off. Again it was off for about 300 miles, I think, and then it came back on again. One day I was driving and I noticed that the light was off once again. It stayed off for several days and then it came back on again. Does anyone know what's going on? I can buy the O2 sensor and replace it, but is the problem the O2 sensor or is the O2 sensor sending a message that something is wrong?? I am not sure what I should do????

Not sure if this helps but at 60k my 02 I35 did the same thing. replaced both o2 sensors and its all good now!

What is the exact code that the check engine light gave you? Sounds like you need to replace the sensor.

I have it checked today at Advance Auto.

Time to replace the O2 sensor. http://www.sparkplugs.com has them for a good price. This thread will show you the location (from the FAQ thread) zerothread?id=120838
