oil sensor could be bad. i would have it replaced because it will mess with the computer . also check to see if wire going to oil sensor is ok, could just be loose wire.
Thanks for your answer. I have unplugged the sensor and verified the wire and plug are in good shape. I will now change the sensor. I was wondering if there was another sensor that fed the message center. Thanks again.
