The other day on the way to work my o2 light came on, concerned me at first but the truck continued to run fine but it used well over a 1/4 tank of gas for a 50 mile trip so I assume it has gone in to closed loop operation (limp home mode )so how do you check the o2 sensor and what are the spec's for it.
