I too have a check engine light that constantly comes on, and when you take it to the shop it says that nothing is wrong.

I have changed my mass air sensor and my knock sensor and my check engine light still comes on and reads that they need to be changed . They said that my computer is not reading them .

i will drive 25 to 65 miles and check engine light comes on.When the code is checked it comes up with different transmission codes the code that came up was P1780.the car starts and drives fine,starts in neutral and park fine.I can't get it inspected until this is resolved and i am not planning on replacing modules and sensor when it could be as simple as an update.a answer from an authority on the matter would be appreciated asap.thank you
bought the car, had to replace the crank shaft and cam shaft sensors, had some other minor work but over all the car has treated me well. I did notice about 30 miles from the garage, my check engine light came on. I bought the car used and there were visible dents and dings, including near the gas cap, I assumed it was a result of something silly like that. I have driven the car another 10,000 miles and other than an oil change and new tires, everything has been fine until recently. I smell exhaust fumes coming up through my vent, I'm assuming it would be a hole or crack in the front exhaust pipe, I'm wondering if this has been an issue for anyone else? im around 85000 miles.
