#3817 of 4184 1999 Nissan Maxima O2 sensor and EGR valve
Mar 07, 2008 (12:04 pm)
I have a 99 Maxima with $205K miles on it. My service engine light has been on for as long as I can remember. I had Autozone check it and the machine pulled codes P0400(Blocked or failed EGR valve) and P0138 (O2 sensor defective). I also had it checked by my mechanic a couple weeks later and he said no code was present and cleared it for me. Of course, a day later the light is back on. My questions are:
Would autozone have a better reader and that's why codes were present?
Can a mechanic tell if the O2 sensor and EGR valve is defective before replacing it?
My car is running relatively good for the mileage and i would hate to spend $350 to $700 replacing these parts if its not going to make a difference.

Is your car eating gas? Stalling or running a bit rough? Do you get a rotten egg smell from under the car?

The last four times I've filled up I gotten between 23 - 26.5 miles a gallon, which is about average. The only thing I notice is when I decelerate and than hit the gas to pick up speed, the switching of gears is not that smooth.

The EGR valve can be tested with a simple vacuum tool; the 02 is harder to diagnose, but a good mechanic can do it with a sophisticated voltmeter (not a cheapie) and with the car running. He can also put a machine on to sniff the tailpipe to see if you are running richer than normal and therefore possibly damaging the catalytic.

Thanks for all your help. I really appreciate it. I went to AutoZone today and now the only code is the EGR valve. I guess the O2 sensor got better - lol.

My car needs coils and spark plugs at 90000 miles. Where can I buy genuine Nissan parts online and get the ones with the new part number at a low price?
#3823 of 4184 Car Pulls to the Right
Mar 15, 2008 (2:07 pm)
I have a 99 maxima SE and my car has been pulling to the right for some time. I just got a realignment (3rd one in less than two years) and the problem is not solved. Does anyone have any advice? I just bought new tires and the air pressure is right. Would bad struts cause the car to pull? My mechanic said they should be replaced soon.

Would anyone know what the ERT is to replace rear brake pads and rotors for a Maxima?

they should last you 40k+. Though it all depends on type of driving you have and the environment.
