    Time to kill and I can't seem to find the answer : I've got an intermittent "Check Engine" light. The Cat code says "290-7". Anybody know what it means?:biggrin_25524:

    Thanks Strider. Any idea what that means, why it's intermittent and how serious it is? Also, I'm not sure it's an ACERT engine. It's a 2006 C15.

    It's deff an ACERT and it could be caused by the sensor on-top of the head, pass side, near the front. I don't know what it is called, but mine kept throwing that code as well and changed that sensor and it went away.
