3 days ago my check engine light came on, so I took it to a shop and had them scan for codes. Came up with the old loose gas cap code. The cap was neither loose nor old (I actually had just had it replaced a few months ago), but I replaced it anyways. The light stayed on, and the mechanic told me they‘re no longer allowed to reset the check engine light for that specific error code. New federal law, apparently. I thought that was pretty weird, but anyhow, the light went off this morning on my way to work. I don‘t know what this indicates, as I‘ve always had the system reset by the mechanic once it‘s fixed. Does it go off by itself over time if the problem has efficiently been fixed?
he's a mechanic and could not fix a wheel sensor and 02 sensor come on guy awaken it particularly is a rip-off believe me run away conceal do not bypass flow he has time to e mail you yet can not fix deliver him a shovel to get rid of the pile of bull **** he's making an attempt to dish out grant him $2000 under he needs or finished value if mounted guess he says no
if the problem is fixed, then the light and code will go away after a while. I never heard of a federal law saying they cant reset the light. i'd see what another mechanic says next time
Nothing to worry about. What happens when a code is given and repaired with the emissions system is that the engine is required to operate for a specific number of drive cycles. This may mean a number of starts and stops and or a certain number of miles that must be traveled before the light will reset itself and the problem will have been solved. You can call the vehicle dealer and ask the parts department or service department how that works on your particular vehicle.
