Hoping someone can help with my 2001 Chrysler Concorde. We've had issues for some time with the check engine light being on, though all seems to be running well. We've had it looked at more than once, they just can't seem to track it down.

Yesterday I noticed this broken plastic hose to the right side of the engine (photo taken standing at drivers side tire). Any idea what this is so I can do some more research?

 

That hose is for the " Cruise Control" and could cause codes. Get a piece of vacuum hose from the auto parts store that fits snug on the rubber ends rather then the tiny plastic hose. may be as big as 5/16 or 3/8.
Key Dance for codes turning engine light on
Key(not start just on) on/off on/off on odometer will display codes then "done"
