Question about 1999 Ford Explorer
KEY ON ENGINE OFF/CRANKING BULBS FAILED KEY ON ENGINE RUNNING BULB CHECK N/A MALFUNCTION INDICATOR LIGHT (MIL) STATUS COMMANDED ON: FAIL
So you are saying the bulb for the check engine light is burned out and needs to be replaced ??
And the trouble codes you listed are for lean fuel mixture which could point to a vac leak or low fuel pressure.

I can tell you for sure that all US models of the Ford Ranger came with a emission system that incorporated a MIL or check eng light, go to the dealer and have them run your VIN on the Ford on line information service, that will give you the engine Calibration of the emission system, you can then find out what emission system was used, export or US.

171 and 174 are engine running lean. Repair cost will depend on cause. Check for vacuum leaks. Start by checking for vacuum lines coming off the engine intake manifold. Make sure they are all attached at both ends and are not cracked, etc. These engines have a lot of intake manifold gasket issues. Spray carb cleaner or starter fluid at the gaskets with the engine running. If the engine revs at all, you have leaky gaskets. This is a bigger job to fix--a few hours labor.
153 and 1151 is an O2 sensor. About $150 bucks to fix that.
If you have more questions, please let me know.

The MIL illuminates during a bulb test and a system test.
A DTC will be stored if a MIL is requested by the diagnostic.
You could have a bad instrument cluster ! Here is part of diagnostic flow chart for your vehicle !
Did you perform the Diagnostic System Check-Engine Controls?
