So I just got one of my O2 sensors replaced because the SES light came on. About a week after the O2 install, the SES light comes back on...

I wondering what's going on now. I just changed me oil prior to the O2 sensor change, but that light doesn't come on for maintenance problems. I am stock everything.

Would Nissan/Infiniti do free error code checks? I'm flat broke here lol

Any help would be appreciated!

 

I would first take it back to where the work was done...

If not, most chain auto stores will do a free diagnostics ( in the hopes to sell you something ).

Yeah I'm going to definitely bring it back to them. The problem is that they can't read the error codes so I do have to find an auto store with free diagnostics.

 

damm what garage doesnt have an OBDII scanner?

 

lol they're new. They just started their own shop but I've been going to them for awhile.

 

I'm not trying to high-jack your thread,
....... I have the same "service engine soon" .......
I have just changed my oil and filter, and also replaced
the spark plugs. The car has always run real strong, smooth idle, no mechanical issues. (battery cable removed during spark plug change)
soon after starting the car,
to check the oil. The service engine light came-on.
The car runs and pulls harder now then it did before. The old plugs were definitely worn and the gaps was worn to anywhere between 0.055" to 0.070".
new plugs were gapped to 0.044" per spec's.
any info would help ! Thanks...

The light just magically turned off yesterday.

Should I go for an emissions test?
