I have a 2000 prelude and just this morning the engine light and ATTS light came on at the same time. I dont feel a difference in the car. I just got my oil changed a couple days ago and there was a nail in one of my tires that they fixed. could this be related? I know i have to get a diagnostics to find out exactly whats wrong...honda dealership said that costs $130. Should i take it to the dealership or will anywhere do? The place i got the oil change is just a regular shop, they said they charge about 70 bucks for diagnostics? Can someone give me some advice? Im broke and i really cant spend so much trying to figure out whats wrong them more to fix it!!!

Thanks!!!

 

CEL will always trip the ATTS light in an SH, the ATTS ecu and engine ECU are connected. Usaully an autoparts store will scan you for free.
