The extra load on the engine may have triggered a sensor. I had this happen to me with my vehicle. I towed my boat to the lake and burned up the catalytic converter, CEL came on. Have the code(s) read to determine what sensor(s) are triggering the light to come on.

    I have a 2004 Tahoe, the check engine came on and I was told it may be the bearing. Could that be? If so, does something else need to be repaired in addition/conjunction to the bearing? Thank you :)
