I replaced my tires yesterday on my 2000 GMC Jimmy 4X4 (235/70/15) with 235/75/15, and my SES light went on within 5 minutes after I left the tire shop. Is the difference in tire size even a possibility for this light to come on?

 

Get the code read.

 

(2) codes came up when I scanned the Jimmy.
P0410
P0452

I had my oil changed last week, and the light went off. It is still illuminated before I start the engine.

 

Do an internet search on those codes to find out what they are.

 

No need for that. We have a section explaining DTCs.
