you have 2 separate issues. one is a parasitic draw on the battery from an electrical component. not passing smog is an emissions related concern involving egr, oxygen sensors, catalytic converters, evaporative systems, and engine overall performance.
Try disconnecting your battery for 2 minuets then reconnecting the battery . This probably will turn the light off.. then see how long it takes to come back on.. I had Mitsubishi that we never could find out what turned the light on.. The dealer even checked it and could not find the problem (did not even charge us) .. When we would turn off it would stay off for a couple of days.. so to smog it we would turn it off, smog it and worry about it in 2 years..Car ran great, always passed smog eaisly and got over 30mpg and went 200,000 miles..
Just because the car seems to run well, does not mean the emissions are within spec. For example, you could be running a little rich and the car will start and run great, but the exhaust is not within code.
What you can do is take it to a "smog shop", that is a repair shop with the proper equipment to diagnose the problem. If the testing is simply the reading of the on board computer codes, then most any place can read those, but you need an experinced mech to know what to do about it. May need an exhaust gas analyzer to physically sample and analyse the gasses. For the actual test, as long as the computer says all is fine, usually, you're good to go.
If the computer looses power any saved run data will be lost and must be re-accumulated to pass the smog test. A few hours to a day is usually enough run time to accumulate enough data.
Its most likely the smog pump or air pump same thing, alot of people used to disconnect it or when the belt breaks or it siezed up they would not replace it until it had to be smogged.It has to be hooked up and working to pass smog.
No any codes will let you fail..Rangers are bad about the valve sticking..But first look on th driverside very back on the intake..Youll see a valve with two vacuum lines The one that goes on the bottom of the valve makes a 90 bend and is bad about breaking..If the lines are good then work the valve by hand and see if it will move
Luckily they aren't as exensive as you think. Look at places like Autozone, they even have re-built ones. The actual bearing can't be replaced, need to replace the whole thing. Let me take that back, it can be done, but is very difficult, and involves cutting welds and re-welding. I've only seen one person actually replace the bearing itself.
NOX is produced when cylinder temperatures exceed 2500 deg. The systems in place to reduce NOX are EGR and the catalytic converter.
If the number is only slightly higher than avg then I would suggest the EGR, make sure that any vacuum lines are attached and that the diaphragm moves freely, be sure not to damage the rubber inside the EGR.
Retake smog test, if numbers still out of range replace the cat.
