Check engine light? You'll need a code eraser to perform this function, and if there is an issue with the vehicle causing the light to come one, which seems to be the case, the issue will need to be corrected for the light to stay off.

The CEL (Check Engine Light) will not go out until you hook up a OBD II scanner to your vehicle and erase the code. If it comes back again after you erase it than either the original problem still exists or you have a new problem. You can go to your local AutoZone store and they can hook up a scanner and erase your code for free.

could just be back on because they didnt reset code after doing the work.

curious to know if you got this solved. Guessing downstream o2 sensor. did your vue idle high? act like it was getting too much gas? Let me know please.

If the light was flashing when it came on, then it means your engine is misfiring.

A solid light can mean anything from a loose/faulty gas cap to a transmission issue.

This light comes on when the computer detects a fault of some sort in its diagnostic tests. If it keeps detecting this issue, the light will remain on. If the light turns off, then it has detected that the issue may no longer be present.

In order to find out what the exact reason was for your light, You need to have your car computer scanned to retrieve the code that the computer would have stored when the light triggered. Most garages will do this free of charge. The code will tell you what may have caused the light to initially turn on.

there are over 200 system faults that turn the check engine light on, have the systems computer tested, there should be a trouble code present to ID the fault(s)

change the air flow meter.
