It's possible that one of the injectors is sticking open. Try running a good injector cleaner through with a tank of fuel. I had the same problem.. It was a leak in the heater core.. Put some alumaseal in the radiator.. I used 2 canisters of the stuff.. then reset the check engine light after a week.
The light is telling you that your brakes are not working properly, which could be dangerous. Your best bet is to get it to a mechanic who can analyze the problem.
There are 4 total oxygen sensors on a ford explorer. Two of them being before the catalytic (Pre-cat, closest to the front of the vehicle), and the other 2, after the catalytic (post-cat). You have to first figure out which bank the bad reading is coming from, then you have to determine if its post-cat, or pre-cat, most autoparts store will be able to tell you if your "CHECK ENGINE" light is on. ?ake sure when purchasing an oxygen sensor for your explorer, that it is HEATED, otherwise nothing will match up underneath. There are 2 sensors between the converters and the manifold. Also, between the catalytic and the muffler. Hope I could help!
There is really no voltage coming to the sensors. The sensors themselves are the ones that generate a small amount of current from the heat of the exhaust. You may want to go to a car parts store, and get a repair manual for your car. They cost about $16.00 Or, go to a Public Library.
you most likely have to change the front hubs with the speed sensors i have tried everything else
I'm not a mechanic / technician but by any chance have you not pulled out the engine oil dipstick . For some reason you are supposed to do that in order for the engine oil to drain
