The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.
The information below is designed to assist with fuel level concerns. The information below are all APPROXIMATE values only.
Note: The fuel sensor values have changed beginning with the 2007 model year vehicles. Be sure to use the correct values based on the model year that is being worked on. Essentially the resistance values are inverted from previous model years.
