    I was driving and all of a sudden the triangle of death came on and my car beeped and engine light came on..I was in the parking lot and pulled over.

    I checked the oil, it was low filled it up then coolant was in decent level too. Added a little more.

    Scared to drive to work.
    Last year engine light came on and it said about a control valve but the engine light went away.

    Saw YouTube videos but people are using different names,.water pump, etc etc makes me nervous which part to take off and install new one..

    I have no experience with cars but if this is doable, can have my boyfriend help me out.

    So that would be P1121 shown in the printouts. It is a fairly common problem. A search just using P1121 will net you a plethora of posts from which to choose.

    If you no longer see an 'edit title' option to change your thread title to P1121, you can use the Report button and ask a mod to do it.
