Question about 2003 GMC Yukon
Where is the Knock Sensor located and how can I replace one.
You will have to remove the intake manifold to gain access to the knock sensors. There are two sensors in the valley under rubber plugs. The sensor in the rear has a tendency to fill up with water and cause trouble. You have to make a dam with RTV to stop the water from getting in there.
